So I know it's been mentioned more than a few times on the various forums here, but I just got done sitting through it once again from the dead center listening position: Soul Coughing's El Oso.

Ho. Lee. Crap.

These guys have been one of my all time favorites for years, and years. Back in the day it was very quietly one of my favorite demo cd's in cars because it was a nice change from the synth bass for bass sake albums, etc.

I realize very much that they have an "organized noise" sound that not everyone will dig, but the cd is an onslaught of bass if you have a sub that can go low enough. Track 5, "Saint Louise is Listening" is one of my all time favorites. The transients go so low, hit so hard, it's like a someone is slapping you across the chest with a tree.

Anyway, the VTF-3 MK4 still amazes me. I sincerely haven't heard a sub go this low with this level of authority and quality in a house like ever.

Looks like the STF-1/2 have the high level input/outputs. The rest of the line-up only have high level inputs.

I had noticed that as well. Which leads me to the question of what are the amps with just high level inputs used for? Doesn't make sense to me.. Unless you run two pairs of speaker wire outputs from a receiver. One to the sub for each channel and one to the speaker for each channel.

Got a question, since the new subs came out recently with more tune options, is there any new ones that would blend in with my 2-3's? I am sure by end of summer I will be able to get the last 2 to fill up my HT!

If you set the Q to 0.7, one port open and EQ1 will be similar to the VTF-2 MK3 in max extension and two ports open EQ2 Q 0.7 will be similar to the VTF-2 MK3 in max output. The MK4s do have higher headroom in the mid bass (about 2 dB more).

I appreciate the help I have found on here.

Room size is approx. 2500 cubic feet. Living room,dining,and kitchen is one large area. Only opens to a hallway that leads to the bedrooms. Because of the window situation the mains,center and plasma have to sit in a corner. We are looking at buying a house where I can build a dedicated HT. For right now I am making do with what I have and can not wait to get everything running,



My equipment is:
Panasonic ST50
Panasonic BDT110 Bluray player
XBox 360
Wii
Denon 2112ci
Emp E55TI's for mains
Emp E56CI for center
Emp E5TI as surrounds
AND NOW A HSU VTF15H

The system will be 60% tv, 20% music and 20% movies

Can you post a drawing of your room? How large is the whole space? I assume 2,500 cu.ft. is just the listening area?

After adding the Q control, we ran out of real estate. Hence we got rid of the speaker outs. Not a problem though. Simply bi-wire from your main amp.

Dr Hsu,

What is the default Q setting of a VTF3.2? Also, is it right to say that one 15H equals 4x VTF-3.2 as far as output?

Previous models have the equivalent setting of Q=0.7. Difference in output varies by frequency. It probably have two to four times the acoustic output of the VTF-3 MK2.

Regarding Audyssey setup, after you put the sub in our suggested location, set the subwoofer to one port open, EQ1, Q=0.7, phase 0, crossover out, volume half way between min and 9 o'clock position. Run Audyssey. The sub has the flattest outdoor frequency response in this mode. Audyssey will then be just equalizing your room. After the EQ, check the sub out level on your receiver. If it's too low, like - 10 dB, you can turn down the volume on the sub further. You want to aim for between -5 and +5 dB on the sub out on your receiver.

After that, set the sub to two ports open, EQ2, Q=0.3 for starters. Tweak from there based on your personal preference. Enjoy!

Dr. HSU, what would be the advice for setting up Audyssey with a 15H and an MBM?

Thanks

Do you have REW or any other means to measure frequency response? If so, do the subwoofer crawling. Place the 15H with the woofer at ear level. Play the test tones and put the mic at the different possible locations for the 15H and the MBM. Do not change levels during this test. Plot all the response curves. The location where the curve is highest below 50 Hz is where you want to place the 15H. The location where the curve is highest above 50 Hz is where you want to place the MBM. Place the MBM and 15H in their respective locations. Set the 15H to crossover out, volume 1/3 up from min, one port open, EQ1, Q=0.7. Set MBM crossover to out. Set crossover on receiver to 80 Hz. Turn off the 15H and MBM. Play 100 Hz and adjust master volume on receiver to get 80 dB reading with meter at the listening position, ear level. Now turn on 15H and play a 50 Hz tone. Adjust subout volume on receiver to get 80 d reading. Turn off 15H and turn on MBM. Play 63 Hz. Adjust MBM's volume to get 80 dB at 63 Hz. Play 80 Hz tone. Flip phase switch on MBM to see which position gives a higher reading at 80 Hz. Leave the phase in this position. Next, turn on the 15H. Play 50 Hz tone. Flip phase on 15H to see which position gives higher 50 Hz. Keep phase in that position. Now you can run Audyssey. After running Audyssey, you can switch the 15H to two ports open, EQ2, Q=0.3.

THIS should be a sticky!

Should I assume that it works the same way with a VTF 3 mk 3? Minus the Q adjustment of course

Yes Dr, I have and use REW, the current location of the 15H and MBM is not the problem. When I attempted to setup my system using Audyssey, I got a serious dip at 50 Hz once Audyssey was done with everything. When I turned Audyssey off, the dip is gone so I know it is something Ausyssey is doing as opposed to my room.

This is a FR of my room with filters applied using a BFD and Audyssey turned off in my receiver.



I don't have a FR saved with Audyssey turned on. I will use your suggestions above and see if it does anything to resolve my Audyssey problem.

Thanks again for your help.

Wow, that is an incredibly good response! I would just not use Audyssey. I never liked the effects of using Audyssey (caveat - the Audyssey I tried was a long time ago).

I think he was referring to Anthem's Room Correction which supposedly can not only deal with spikes it is capable of dealing with dips I personally have not had a chance to play with it want to though.

Eric-T, what does ARC stand for in your comment? I assumed it was referring to Audyssey Room Correction since all the discussion was about Audyssey... My bad if I mis-interpreted it! I certainly have not tried Anthem Room Correction myself.

The term "ARC" is more than a little confusing, as it's also used for "Audio Return Channel".

I had YPAO on my last receiver and can only compare it to that. It was a HUGE leap forward in the SQ department and does a excellent job blending the sub into the setup.

I have to buy an Anthem receiver or processor to try it! Expensive!

Re: Audyssey and other auto RoomEQ(s).

I could spend countless hours randomly trying various speakers in my room, hoping that at least one random pair of speakers will have a complementary freq response for the environment. Then I could either a) spend hours/days/years randomly adding acoustic treatments to the room until I get it sounding "right" or b) spend hours/days/years with something like REW while adding acoustic treatments until I get it to measure "right" and sound "right" ... or I could:

Pick a pair of speakers that has a neutral anechoic response and an impedance/sensitivity profile that matches well with my amplifier/AVR, then spend 15-20 minutes or so letting "Audyssey" do it's thing ... pop the corn, pop the top, pop in a BD and enjoy the movie ...

Which is a long way of saying, I think it might be a mistake to dismiss MultiEQ-XT ... It's probably not anywhere near perfect, but it I think does a lot better job than most Joe6Packs (or even self-proclaimed "audiophiles"/enthusiasts will be able to do on their own.)

PS: My VTF 3.3 (foolishly didn't get the turbo when I had the chance) is still shaking the foundations. After watching "The Pacific" last year, I'm afraid of it.
