VTF 3.3 Max Output Mode

Greetings,

I am very close to placing an order for one. This will replace a Mirage Omni S12 subwoofer.
I need to know will the 3.3 in "maximum output" mode hit 18hz/20hz with authority? My Mirage S12 dramatically decreases in output lower than 25hz. At 20hz its really drops off to basically a whimper.
I am really hoping that the VTF 3.3 is a big enough upgrade over the S12

Thanks

I have dual 3.3s and they are in Max Output with turbos and I get down to 15hz flat thanks to some room gain!

With two 3.3's on MO you can get down to 20 or even 18 in a room without the Turbo. It all depends on how you have them setup and the room. I run mine with MO and no Turbo because I like the slam that you get. Turbo's tend to be softer then MO.

Curious as to what people are getting with only one 3.3. Some reviews I have seen say 21-22hz.

When I had just one 3.3 Pete Hsu would say that in MO you could still get to 18hz. Yes it depends on the room but, I am sure you will not be dissappointed. Lets see if Pete Hsu will come in here and answer your question. You will need to provide room dimensions.

The frequency response of the VTF-3 MK3 in max output mode when measured outside and away from reflective boundaries is +/- 1db from 20-200Hz. So one should get strong in-room extension down to 18Hz or even lower.

Sincerely,

I never have ran REW to see what mine do, but when I engaged the 15-25 hz lift (gives a boost of 3 to 4 db in that hz range) on the Anti Mode (sub EQ on LFE line) I could hear the boost kick in and then drop off. So I suspect that I was down looooooow!

Thanks Pete! Is that with it switched to 25hz instead of 18hz?
I would be placing this sub 5" away from the wall between my center channel speaker and right front main. The room is 16'x17'x8' open to a kitchen about the same size.
Pete, have you heard the Mirage S12? If so, how do you think it compares to the 3.3?

Thanks

My 33 without Turbo in MO in front left corner (snug) achieved 17.8hz, that is flat (75db). so to answer your question "will the 3.3 in "maximum output" mode hit 18hz/20hz with authority?" YES !

15x24x8-12 or 4200cf with 1800cf opening to rear right of LP

I found having the drive facing front wall and ports facing side wall worked best for me.

Gov, that frequency response is with the bass extension switch on the sub amp set to '25 Hz - 2 port open' mode.

Here is a review of the S12 where it was compared to the older VTF-3 MK2: http://www.hometheatersound.com/equi...e_omni_s12.htm

The VTF-3 MK3 has flatter frequency response than VTF-3 MK2, and has almost double the port cross-sectional area too.

Sincerely,

Question for Pete or anyone.....I would be placing the 3.3 about 10" away from my CRT RPTV (right side of it) and about 4" away from the wall where the ports are. I have my Mirage there now and I get no magnetic interferrance. Do you think the 3.3 would be problematic in that placement?

I placed my order this morning! Can't wait to get it!
Should I buy a "Y" adapter for LFE in on the sub? I plan on using my receivers crossover, not the sub

Thanks

Gov, you won't need a y-splitter, just run a single-ended rca cable from the Sub Pre-Out on the receiver to either the left or right rca input on the subwoofer.

Thanks so much for the order, hope you like it!!!

Received my sub today and in perfect condition! This thing is HUGE!!!!!! My wife had a very shocked look when we took it out of the box But, I love the smooth seamless look of it. From my limited time with it I can tell you that it is better than the Mirage omni-S12, but that is no suprise to most of you. I have not really opened it up yet, but from what I hear it sounds fantastic! I played a bit of WOTW at about -15MV and was blow away!
Oh, I am running it in MO at about 9:30 on the output dial on the back of the sub and -2.5db on the receiver SW trim.

I tested my new 3.3 in ME mode today and really gained a lot under 25hz in my room. I played the first song on the test CD included in the purchase and "Oh my god" did it sound awesome! That 16hz pipe organ was crazy! In MO mode it was less spectacular. It seems like above 25hz I am only losing about 2 db in ME vs MO. This is all uncorrected on the Rat Shack SPL meter. Does this sound about right in most rooms?
I wonder if I should leave it in ME all the time.

Yes and yes (if you want deeper bass).

Gov,

I've been running my 2.3 in max extension mode almost from day one. I tried it in 2-port, max output mode but found that I really like the deeper bass from the 1-port, max extension mode. I plan on adding an MBM-12 soon to help fill in any mid bass that is lost by running in max extension mode.

Hey Gov...same response from me here and at AVS - ME all the way for me. I felt a more 'broader' bass in MO, but not the deep bass like I do in ME.

Thanks guys! I actually like both modes very much! I did a lot of messing around and basically, in my room, 22hz and up MO really kicks in. In ME bwteen 16hz and 22hz it really rocks!
I think I will end up keeping it in MO most of the time because I don't ever listen to a pipe organ (except on the HSU CD ) and that I have a rather large room to fill with HT.
Its nice to switch modes if I want to and it takes less than 30 seconds to do it! I am very happy with this sub! It does everything right!
