Just picked up two more of these highly addictive modules. I am afflicted with midbass madness.

Now what?????

it's a disease and there is no cure. Acceptance is the path to recovery.

These MBM's are just so easy and fun they're like legos. Probably the best (and worst) part is the instant gratification benefit that comes with being within 20 minutes of HSU labs haha.

Now youa re being cruel...It is not fair. I am in Puerto RIco...NOOOO!!!!jajajjaj

[Pete_Hsu]

Ron, when you called and asked for two more, I was like "Are you serious???" :D

I am certainly envious, and am looking forward to the day when I can come to your house and listen to the system :)

Take it easy man...

WOW a Conquest + 4 MBM's...I just can't believe it!WOW

[Pete_Hsu]

Actually I think the plan is to add more true subs as well later this year :)

Do you have enough room left in your HT area to sit and enjoy your toys?

[Mia&Lana's dad]

I just finished experimenting between stacked MBM's flanking the mains or side by side in order to determine my final preference.

Pete, you were right - Four on the floor it is!

Would you explain to all of us what you mentioned to me at the shop for tech reference? I don't remember the exact terminology you described.

I still have some room to play....

[Pete_Hsu]

Holy cow Ron, amazing. Beautiful work :)

How does it sound with the center channel higher than the main speakers? I suspected that your MBM's would sound best when placed as they are due to less chance of floor bounce.

[cschang]

Wow!

Hey! Nice speakers! :D

How about stacking the MBMs and then placing the Sierras on them to get them to the same height as the center? Then again, I don't know how tall that Conquest really is.

[Mia&Lana's dad]

Since the TV is mounted up high, the center channel seems to be anchored better where it is now on top of the Conquest. Previously, I had the center on its own TP-24 stand and I prefer this much more. The center is isolated with auraled mopads on a 4 degree downward tilt. The left and right sierra's are tilted upward sitting on the mopads also 4 degrees. They seem to converge pretty well at my listening position, 14' back.

[Mia&Lana's dad]

The conquest is 36" tall and the MBM's are 19". The mopads add a couple inches and so the sierra sits really close to where they used to on the TP-24 stands since the MBM's are also on top of auralex gramma. The center is obviously horizontally positioned so the difference is really not bad at all. I think it would be very similar to centers placed on top of the TV at a typical eyelevel position.

[cschang]

ahhh....when seated, 36" is fine.....same with 19" I think.

I need to hear that setup!

oooohhh....I just had a thought. Replace that Conquest with two of the new Hsus when they come out.....hehehe!!!! :D

[Mia&Lana's dad]

Up front I can still stack. I have the side walls and rear available for even more woofage as needed!

I'll have you guys over as soon as we get the rest of our contents out of storage. Bring funkmonkey with you!

[bsoko]

Hmmmm, now you got me to thinking!

Bill

[Mia&Lana's dad]

Can you guys believe that my wife hasn't noticed the new pair? That's how seamless and transparent the MBM's integrate! I'm going to keep adding more if its always going to be this easy... buwahahah.

[cschang]

Out of curiosity....are the speakers set to small? If so, where are they crossed over?

[Mia&Lana's dad]

yes, small @ 150hz!

As I said on AVS:

I just finished re-running audyssey after repositioning the MBM's up front with the mains - still 3-way split sub/LFE. Conquest x/o @70hz, & MBM's internally bypassed (out setting on back of amp) running all the way up to whatever x/o selected at the pre-pro. I chose to set the Sierra's to 150hz all the way around. While I haven't measured the FR yet with REW, I am really pleased with the rearrangement and tremendously improved sound quality compared to where I had the MBM's previously nearfield. The switch has not compromised punch and slam whatsoever. In fact, to my ears, impact is now well defined, blending seamlessly with the Conquest and Sierra's. The front stage is now a unified field of sonic sweetness.

I am really impressed with the ability to x/o @150hz now. Although I tried to keep an open mind, I went in with some skepticism as I was very accustomed to the hollow, tinny, tunnel sound that was accompanied by sloppy, muddy voicing that found some of its way through the 18" Conquest driver when I would experiment with it this high in the past. I am a believer and curious to explore if there will be any improvement running the MBM's in stereo.

Thanks again for the help everyone!

[Mia&Lana's dad]

There's some music material (SACD/DVD-A) that I prefer listening in Direct mode, bypassing the x/o and Audyssey. The integra implementation also rolls off the high end unless you're in a THX mode when Audyssey is engaged. They've said that adding +2db treble on the tone control helps this. It seems to do okay for 2-channel when I want Audyssey engaged.

For the most part, these further enhancements are primarily targeted for effortless HT and the ability to go from 0-120 in a blink of an eye. I love turning on a dime, the system handles so smooth, quick, fast, deep - on and on til the break of dawn!

[cschang]

Thanks! Very interesting!

[cacihome]

One question,

THe volume knob on the 4 MBM's is set where? At 9 oclock?

[bsoko]

With a spl meter, what are your MBM's set at? Also, your main sub?

[Mia&Lana's dad]

yes, the mbm's are roughly at 9 o'clock, with very, very minute fine adjustments to bring them all back down when all the subs are powered on. As fellow mbm owners, you guys are very familiar with how sensitive the gain control is right? Anyhow, I calibrated the entire sub array to 75db @ 14' with RS analog SPL meter. I think I did pretty well considering Audyssey set main sub level to just -1db. whoohooo!

[Pete_Hsu]

LOL, that's so funny that your wife hasn't noticed the two extra MBM-12 :D

Leo and I are looking forward to stopping by later in the year...

Hi Ron,

From reading your thread over at AVSForum, you have your crossover in the Integra set to 150 Hz and then are using the crossover in the Conquest at 70 Hz. This works great, but I tend to ask, "What will make this better?"

There are some proponents of stereo subwoofers and I think Lexicon and Denon now have some bass management features on their top of the line Pre/Pro's that allow one to have independant left and right stereo bass channels. I looked up your DTC-9.8 and see that it has a digital output. I'm not sure if it combines all channels into a stereo PCM signal. If it does, you could send it to a Behringer DCX2496. This would provide full range L and R signals so that you could perform crossovers and send L and R signals to your MBM-12's.

Man, I would love to hear what the lightning scene from "War of the Worlds" sounds like with your system at reference level. :eek:

mojave, you're my subwoofer angel and guiding light! Actually, I never stop researching how to improve. Definitely crossed over the point of diminishing returns long ago. Active crossovers seem to be the next frontier, bypassing the Fmods passive inline filters you introduced me to. I first learned of the DCX2496 being implemented in Emerald Physics CS2 speakers as its crossover.

What camera and lens are you using?
I must buy myself a decent digital camera one day for I'm sick of my old Kodak. ..... (poor tradesman/poor tools)

Beautiful pics, the photography is very nicely done. And now I know where the king sits :D

[Mia&Lana's dad]

just picked up some new blu-rays today:

Twister (Tru-HD)
Master & Commander (DTS-MA)
Hitman (DTS-MA)
Chronicles of Narnia (uncompressed PCM)
Blackhawk Down (uncompressed PCM)

let's see how well these tracks sound whoohoooo!

[thsmith]

Hitman actually has a lot of great bass

[Mia&Lana's dad]

agreed, there are two scenes which I go back and play over and over but it sounded great throughout when the content demanded it unlike some nonstop tracks where your tolerance has already built up and no longer surprises you. That's why I think headroom is important so one can rectify that problem with a fingertip.
