Where do you set your crossover at, on your reciever?
 
Where do you set your crossover at?

I just wanted to see if any of you guys experimented with the crossover setting on your "Reciever" for your sub and where do you leave it at....

I normally leave mine on 80hz but noticed on some movies it seems to give slightly more and better bass at 100hz...I guess I will use the 100hz for movies and 80hz for music but wanted to see what everyone else was setting theres on...

Also list what sub you have...I have a VTF3-MKII

Thx,
Claude

Mine is an old Pioneer 509 VSX 5x100watts with DD/DTS decoder which can also accept 5.1 Analog Inputs for SACD/DVD-A playback. I have 3 different settings 100hz, 150hz and 200hz for the LFE frequency.

Pionner recommends setting it to 200hz for small speakers configuration in its manual (this seems to be contradictory to me) but I set it to 100hz. I wish the receiver could have variable frequency settings because I would like to be able to set it lower than 80hz and not at 100hz. But I have to live with what I have. It will be one of my requirement in future receiver purchase.

So far I have no complains!

Sub is VTF-2 Mk2.

Just out of curiosity, to whoever voted the frequency below 80hz, which brand name of receiver allows you to set it? Thanks!

My receiver (Panasonic SA-XR70) has crossover settings of 100Hz, 150Hz, and 200Hz. But I run my main speakers (set to "Large") through my STF-2 and set the sub's crossover to 70Hz. It sounds great this way.

Since I listen to two-channel stereo 90% of the time, I prefer this setup. If I did more HT, I would definitely use the receiver's 100Hz crossover.

cschang March 17th, 2005 7:04 AM

tafguy...my old HK 525 let you set the crossover as low as 40Hz, and so does my current Sherwood/Newcastle P-965 pre/pro.

Dudley March 17th, 2005 7:31 AM

I don't have one (I voted 80 Hz) but the new Yamahas, Onkyo and Denon all allow crossovers below 80. There are others as well, but I am not as familiar with them. Not sure about all the entry level models, but you don't have go very far up the line these days to get that feature.

Gotta love the trickle down effect - recievers keep getting better.

DNelms March 17th, 2005 8:06 AM

I am a mindless sheep
 
I have mine just set to 80hz.

I just set up my B&K at the THX standard with all speakers set to small, sub at 80.

I have a VTF-3R. (I love it!)

tafguy March 17th, 2005 9:20 AM

Thanks cschang and Dudley for receiver's info!.

And you're right, manufacturers of today's receiver are better to go to that direction of allowing consumers that nice feature for better fine-tuning. For 2.1 mode, I like to be able to lower that LFE cutoff frequency of 80hz further down, not that I'm against with THX specified norm which is perfect for a type of application like the Vents which has its center channel lowest frequency response down to 80hz but for other speakers which are bass capable eg. freq resp of 50hz, that high frequency like 80hz or above lead to directional perception. 100hz is average, 80hz is good and lower is excellent, at least in my own opinion.

Lwang March 17th, 2005 10:33 AM

I have set my to 51hz via Hsu's 500w amp. But the Meridian processor allows me to set it it from 30-120hz of freq in 1hz resolution.

Lwang, from your frequency cut off setting to 51hz, may I ask what kind of main speakers you have and what are their frequency response? I would guess they can reach lower than 50hz. That Meridian processor of yours allows you to do increment/decrement cutoff of 1hz is really nice.

tafguy

Lwang March 17th, 2005 7:34 PM

tafguy,

I have the Magnepan MG-3.6/R, with a freq resp of 34hz-40khz. Since they are dipole planar, which loads the room very differently than enclosure based woofers. That is why I am going as low as possible on the crossover freq in order to preserve the sound of the maggie bass.

I don't use the Meridian's crossover because it follows THX's crossover scheme of 2nd order HP and 4th order LP. The crossover in Hsu's amp is 4th order HP and LP.

Active Speaker March 23rd, 2005 1:29 PM

I use the 51 hz crossover point through the 500 watt amp. I set my receiver to no sub and large main speakers. I use the high pass between my amp and the Hsu amp. I've read several places that doing it this way (not using the LFE output) does not limit the bass in DD or DTS. In any case, for me that's the way it has to be set up.

tafguy April 12th, 2005 3:51 PM

The affordable new A/V Receiver TX-SR503 from Onkyo is worth to check out allowing different LFE signal cutoffs at 60, 80, 100, 120 or 150Hz. Driving the Vents can not be better at the price of $300.

lmm June 17th, 2005 6:45 PM

I've tried different setups for crossovers. Ascend 340s (rated down to 55hz) fronts, and Ascend 200s rears.

The latest setting was 60hz (using HK635). My center channel is sitting on a shelf in a cabinet, and I think there's some cabinet buzz/rattle at lower frequencies. I have an Auralex MoPAD on order to isolate the center speaker from the cabinet.

I imagine the base localizes a little better at 60Hz than at 100hz. I watched "House of Flying Daggers" last night, turned up loud, and when the horses are galloping across the room, the bass was tracking the sound pretty well!

95 Silver TA June 15th, 2006 1:10 PM

Since this is over a year old, I wanted to see what some of the newer responses were and for those lucky few with the HO could respond too :)

I have twin turbos. I have PMC IB1s for mains. They are a TL design with good response below 40hz (30hz is about the practical limit) and excellent, "tight" bass. Like most of the PMC line, they can play very loud and clean. I have the xover set at 40hz. I may try a slightly higher xover in conjunction with some relocation experiments, but with my current locations, the sub interactions are causing a big null at the seating position at 60hz, the IB1s seem to smooth this out considerably.

DNelms June 20th, 2006 5:17 PM

This may change when Dr Hsu introduces the MBM-12......

AdilM June 24th, 2006 10:28 PM

Maybe the crossover will change. It might not as well.

I have the VTF-3HO Turbo with Ascend CBM-170s (classics) and a classic CMT-340 center. I run 80Hz from my AVR-435.

I just wish the HK didn't have a high pass filter at 15hz with the auto-eq enabled....the response drops off really fast there and I think I'd get good in-room extension to 12hz without it. Oh well.

DrewB September 24th, 2006 6:15 PM

I have the Pioneer 1014 and my crossover has been on 50hz for a long while. Well, I went back to 80hz a few days ago. With 80hz it seems like I'm getting too much bass from too many scenes that shouldn't be that low or loud. Not sure if that makes sense. Anyway, I will be be trying 50hz again shortly.

cschang September 24th, 2006 6:50 PM

When you change the crossover, you may need to calibrate again. Also, you maybe getting added bass reinforcement due to the placement of your main speakers.

Are your mains set to small?

DrewB September 25th, 2006 6:48 AM

Curtis, I assume that you are addressing me. That's a really great point to re-calibrate...I did not think of that. Yes, my mains are set to small.

cschang September 25th, 2006 6:56 AM

Yup...all you buddy! :)

Also, in my room I play around between 60 and 80hz. I one point, due to where my mains were, at 60hz things sounded a little boomy. Just changing placement a few inches changed that.

skriefeal November 14th, 2006 8:51 PM

I voted for 80hz, but then realized that I actually have my Yamaha RX-V2400 set to a 60hz crossover with my VTF3-HO. Oops!

wuchi November 22nd, 2006 5:09 PM

depends on -3db point for mains, i'm at 60hz

those PMC's need a lotta juice but when supplied they will crank out the volume, by design they have very quick bass to 40hz, you have to crossover those at 40hz which I think is ideal anything above that would muddy the sound. that design is about ten yrs old, when you buy them?(excellent monitor)

  • 80 Hz crossover setting
  • B&K Ref 31 pre/pro
  • 2ea. VTF-3HO's w/turbos
The B&K will allow just about any crossover setting.
Things may change with the introduction of an MBM-12, though......we'll see.

I am waiting for my MBM also but my concern is how do I set the subwoofer speaker distance on the receiver since 1 will be nearfield and the other 14 feet away.

Oh I cross over at 80Hz. Do not want to get to far off topic.

NO, good question.

jimijim January 17th, 2007 7:35 PM

I set mine at 60.At 80 or even at 40 I seem to loose alot of mid bass (punch) i`m running Polk rti 12`s which do a pretty good job with the mid bass.Although I do believe in the future I will get an MBM.First, I think I will add another VTF-3 HO.

AudiblConoiseur January 18th, 2007 7:11 AM

Would like to know how you did that
 
How did you set up a poll option? I want to do this with receivers. Please let me know or send me a PM so I can call you and find out. Thanks!

xcjago February 1st, 2007 7:00 PM

I have my Ascend 170se crossed over at 80hz to my VTF-3 HO. I also used 80hz for my 340se.

Some people don't realize that just because your speakers can play down to 50hz, doesn't mean that's where you should cross them over. A good subwoofer like the HSU will be able to play 60hz at higher volumes with much lower distortion than any bookshelf speakers, even the 340se.

p.s. I just added my BFD EQ to my VTF-3 HO and it is sounding much better. I was able to reduce a peak around 40hz as well as boost the 70-80hz bass giving me more of that mid bass punch.

You cannot do it from your receiver. If you want to set a different distance setting for the MBM you would have to purchase some sort of audio delay device.

Mains rated to 28Hz
 
If my mains are rated to 28Hz, should I keep my receiver at 80 or move it lower?

xcjago April 4th, 2007 12:12 PM

Looks like your mains are fairly capable. I would try 60hz and see which one you like better.

Thanks,

Yep give 60Hz a try. One way to judge a good spot for your crossover is to set the crossover one octave higher than the extension of the speakers. For 28Hz that would be 56Hz so 60Hz should be great. Setting the crossover at least one octave above the speakers extension leaves room for rolloff since we know crossovers slope and drop off gradually and not just all at once. My mains go down to 30Hz and I run a 60Hz crossover and the sub and mains blend better than at 80Hz in my system. Give it a try the main thing is not to set it too low, because that could damage your speakers during big action movies like WOTW, so I wouldn't go lower than 60Hz.

aht3 April 5th, 2007 4:33 AM

Thanks for the replies. My receiver goes from 80 to 50 so I am going to leave it at 80. Thanks again.

Interesting comment. How could you damage your speakers by setting the crossover too low? Does not the receiver drive the mains and the subwoofer amp drive the subwoofer? My concern stems from setting my mains to "large" even with the subwoofer (due to midbass problems). It would seem I run a risk based upon your comment. If you could expand upon your comment I would appreciate it. Thanks.

I think you are confusing amp power with frequency response and crossover points. You are correct the receiver's amps do drive the 5,6,or 7 main speakers while the sub's amp powers the sub. This is amp power, but where talking about damage do to sending frequencies to your speakers that they are not capable of handling. By properly setting the crossover you send only the frequencies to a speaker that it can handle and let the sub handle the lower frequencies that the other speakers can't.

If you set your receiver to "LARGE" then your speakers will get the full DD or DTS signal recorded for those channels, lets say front L&R channels also known as your main speakers. If a movie like War of the Worlds for instance has bass recodred as low as 20Hz in the front L&R channels(I'm not talking LFE just regular bass) then you front L&R speakers will get a 20Hz signal. Now if you front L&R speakers only extend down to 40Hz then your risking your speakers. At very low volumes this won't be a problem, but at any normal movie volume you're in for trouble.

Now let's take the same situation as above and apply it to setting your speakers to "SMALL" and running the crossover at 30Hz. When you set your speakers to LARGE they get the full signal recodred in a channel, but when you set them to SMALL they only receive the signal "above" the crossover everything below the crossover goes to the sub. So if you set them to small and set th ecrossover to 30Hz, but the speakers only extend to 40Hz then you are allowing at the minimum 10Hz more extension than your speakers can handle and this is bad.

Now for the kicker. Even if you set the crossover to 30Hz the crossver has a slope and doesn't just stop the frequency at 30Hz like a brick wall. It acually allows the signal to reduce in volume starting at 30Hz and depending on the slope it will gradually drop off the volume over a number of Hz. This is why you should set your crossover 1 octave above the speakers lower extention. Some people just set the crossover 20Hz higher than the speakers extension and that gives enough room for the slope and eliminate damaging the speakers.

It's your call, but there is no reason not to try 50.

I suspect 60 was recommended because it's more commonly available than 50. While 2X the mains' cutoff is often suggested, 1.5X is also frequently mentioned. In your case, that would be 42Hz. Others like to add 20Hz, would would be 48Hz for you.

I'd suggest you give 50 a try and let your own ears decide. With the gear you have, there is no chance you'd damage your main speakers, at least not at any rational listening level. :cool:

lradden April 5th, 2007 8:47 AM

I like the one octave rule, but with your speakers I'd agree with MacFan and try 50Hz. The one octave rule came about because lots of manufacturers exagerrate their frequency response and it just gives an added buffer if they exagerrated a lot.

Great thread. Just purchased a VTF2 mk3 to go with my axiom m22ti. Where would you recommend setting the crossover with these? I'm using a HK 430 with crossover options at 60, 80, 100 and 120. Attached is diagram for the M22s. Thanks in advance.:)

cschang April 16th, 2007 1:15 PM

60Hz-22kHz +/-3dB looks about right to me. If you use about 87dB as your mid-point, -3dB would be 84dB, and +3db would be 90dB.

The interpretation of "+-3dB" is what is in question....some companies use it as a 6dB window, others use it as a 3dB window.

lradden April 16th, 2007 1:45 PM

Curtis going by the -3DB being 84dB as you stated then a 80 Hz crossover should work.

It just seems odd that the speaker drops 26dB from 88 to 62. I know the response states 60Hz - 22kHz, but isn't that a large enough drop off not to rate the speaker 60Hz - 22kHz?

I know I'm digressing, but I'm just curious.

Are you sure you are reading that right? I see a 8-10dB drop from 88hz to 62hz.

MNSACD April 17th, 2007 6:26 PM

Any recommendations for me? I use Polk LSI 15 front speakers, and Polk LSIC Center. I have my receiver (Sony STRDA4ES with Emotiva LPA-1 Amp connected to pre-outs) crossover at 60Hz. I have the HSU VTF3-MK2. I think it sounds good but sometimes wonder if the middle is a little week. Thanks!

MNSACD

lradden April 17th, 2007 6:45 PM

Looks like your Polks have extension down to 32Hz just like my Monitor Audio Silver S10 speakers. I've run my S10 at 60Hz for a long time and felt the middle was a bit thin. Then I started running them at 80Hz and the middle improved. I find that the sub integrats better at 60Hz and is less localized and at 80Hz I can tell where it's at more especially with music. I find that for me a flat calibration is weak and I run my sub 4dB hot and that adds the extra ooomph in the middle. Really since your speakers extend to 32Hz you can try both and see which sounds best to you. I know the dilema here you go and buy speakers with nice extension and you don't want to set the crossover at 80Hz and waste all that extra extension. Try running at 60Hz with the sub 3 or 4dB hot and see if that adds the extra punch in the middle you're looking for. It works for me.

cecilsaurus April 18th, 2007 11:59 AM

Thanks for the response guys. Iradden, I had to look twice at the axis as well:D.

Thx,

My pre/pro is adjustable from 120hz - 40 hz in 20db increments...I like 60 hz x-ver setting. My mains are set to large as they go into the 20's themselves with the woofers being biamped, center set to small which gets crossed over at the 60hz, and surrounds set to large as they are 8in in ceiling rated to mid 40's hz. So only the center is being cut off at/about 60hz...the rest are producing full range as designed. The idea to set spkrs to small vs large is really about the burden on your amp's and/or how well the mains blend w/ the sub keeping in mind that subs work best down low. I cringe at the suggestion of setting all my speakers to small and send all predetermined freq's to sub by the x-over setting chosen. Why waste that upper bass, lower mid bass punch when it is the mains providing that punch. Bottom line is try what sounds best in your setup. My multi ch amp is only driving the mids- up. I think many people x-over the mains to sub too high and it sounds full but boomy rather than deep/tight/quick.

So only the center is being cut off at/about 60hz...the rest are producing full range as designed. The idea to set spkrs to small vs large is really about the burden on your amp's and/or how well the mains blend w/ the sub keeping in mind that subs work best down low. I cringe at the suggestion of setting all my speakers to small and send all predetermined freq's to sub by the x-over setting chosen. Why waste that upper bass, lower mid bass punch when it is the mains providing that punch. Bottom line is try what sounds best in your setup. My multi ch amp is only driving the mids- up. I think many people x-over the mains to sub too high and it sounds full but boomy rather than deep/tight/quick.


I run all of my speakers at "Large" with my LFE at 80 hz and the reciever sub setting as just "Yes" and not "Plus" (double bass, LFE and main bass through the subs). I will use the plus though if I feel that the bass is lacking on the LFE.

I'm good with 60 hz,but it took trial and error to find the sweet spot!:D

60HZ, ALL SPEAKERS LARGE RUNNING lfe+MAINS

CK01 January 5th, 2009 11:45 AM

I'm struggling with the Hz setting on my Onkyo TX-SR606 and I hope someone can help me out.

I have Mirage nanosats for my front speakers with a frequency at 100 Hz-20 kHz (+/- 3db). My subwoofer is the HSU STF-2 with a volume position at 12 o'clock. I have placed the subwoofer nearfield under my end table near the wall (for WAF).

I have my speakers at the "small" setting and the automatic Audyssey settings selected the following Hz for the rest of the speakers:

FL: 120 Hz
CC: 150 Hz
FR: 120 Hz
BR: 120 Hz
BC: 120 Hz
BL: 120 Hz

My question is what setting should I have for my subwoofer? The Mirage Nanosat manual recommends setting it at 120 Hz, but I am getting some sound localization at that setting. Is it ok to set at 80 Hz for the sub and have the 20 Hz gap?

Thanks!

CK, what is the highest crossover frequency you are able to use for the subwoofer before it starts to become too localizeable for your tastes?

One thing you can do is, keep everything as is on the receiver, and then set crossover switch on the subwoofer to 'In', with crossover knob all the way to the right (90Hz), to see if things sound better that way.

CK01 January 6th, 2009 7:03 AM

I'm at 100 Hz right now and it seems to be working fine in most situations, but I'm not totally convinced. At 120 Hz it was very noticeable.

I'm going to try your suggestion tonight and reply back. Thanks for the quick response Pete.

Pete,

Does it matter if the receiver is set at 80 mhz when my HO is set at 60 mhz (which one will take precedence)? At the HO, i have set it to "in".

crossover confusion
 
When I set up my system, I used my receiver's set-up program and it came up with some strange settings. It had my sub as a 10 inch, and it also had most of my speakers set to large, and the distances set all wrong. I went through the setup program manually after that and changed everything to what I thought would sound right, with the help of the manual. I of course bypassed my sub's crossover, and changed all the speakers settings to small and set the crossover to 80hz. It now sounds pretty darn good. When I compare the settings between the manual settings that I put in and the receivers settings using the microphone and set up program, they sound pretty close. I was shocked. Go figure.

Tony, if the subwoofer crossover frequency on the receiver is set to 80Hz, then that is the frequency where the MBM will be crossed over to the main L/R speakers. Setting the subwoofer crossover frequency on the HO subwoofer to 60Hz is fine, because that will roll off frequencies above 60Hz from the HO.

At least they sounded comparable! Sometimes the manual settings will end up sounding much better than the auto settings :)

I currently run mine at 80Hz because no matter how many settings i tried and my Integra DTR-10.5 will allow down to 40Hz and the Paradigms V3 100's start to sign off at that point its just the VTF-15H handles all the frequencies 80Hz down with ease and more authority. Which in turn helps the dynamic headroom of the AVR handling frequencies 80Hz and up.

80 hz crossover with 4 Submersives subs.

Below 80 HZ

I use 60 hz on a Marantz SR 5005 , I have Kef LS 50 & recently acquired VTF-15H MK2

What is the best crossover?
 
I've changed it from 60-100hz and can't tell a difference unless I go lower and you then you don't notice much coming out of the sub.
What material is best to try to hear a difference in the crossover movies, music?
What do you look for while listening?
