  1. Any recommendation for ports, EQ, and Q settings? Primarily a movie and tv fan. (95% movie/tv to 5% music)
  2. Since I have a Pioneer receiver, I have the MCACC EQ. Is it worth doing? I have a SPL and could manually configure, but wasn't sure what you all thought.
Let me know your thoughts if you have some time. Thanks!
The HSU manual has recommended settings for your sub before running your Auto calibration routine... typically one port plugged, EQ 1 and Q control at .7 if I recall correctly....then when that is done, you can set your ports, EQ and Q-control for the type of bass sound you like...

Good deal! Can't wait to get the sub delivered and calibrated.

Hi I have a Hsu VTF-15 and VTF15MK2 subs hooked up to an Onkyo 828 receiver, and I have found out that my receiver needs an amp to fully power the second subwoofer.
Does anyone have an amp that they would recommend for the subs? Everytime I look for an amp, I see amps that are designed for cars, and I'm assuming I need a more specific type of amp for a home theater?

uhhhhh, you are confused about using 2 subs with your Onkyo... You do not need amps for HSU subs, they have their own! If you can't get one of the subs to activate, you may need to rerun your Audyssey setup again to identify that you have 2 subs hooked up...

Got my second vtf-15h and did the calibration last night with my denon 4311ci. Sub 1 was at -5.5 and 2 at -6.0. Should I rerun the calibration and try getting closer to 0 +/- 3.

No, go watch a movie at reference levels or levels that you enjoy and listen to them work.

Couldn't agree more! I've had a VTF3 MK3 Turbo for going on 8 years. It started out as a joy and has remained so to this day.

Do you have any issues with the turbo pipes staying snug in the back of the sub? I scooped up a turbo unit for my vtf3 last year. While I like it, I have run into this problem on occasion.

The Turbo unit has been just as solid as the sub. Have never had any trouble with the turbo tubes becoming loose. That said, I bought the Turbo new and have been very careful on the few occasions I disconnected it from the sub.

I'm building out my media room in about three months and I'm going to go with an HSU sub. The room is small (11x12x10) so I didn't want to buy a large sub and leave too much headroom on the table. I reached out to HSU and asked them for their opinion. Here's their response:

Quote:
I would say that you should be good going with the VTF-1 Mk2 or
VTF-2 Mk4 for that room. Your room isn't all that large, so the VTF-1
and VTF-2 should be able to pressurize that room quite nicely and give
you quite a bit of clean headroom. I would recommend going with one
of the VTF series because many times in smaller rooms, you tend to
get a lot of boosts/room gain in the deeper bass which would make
the sub sound a bit boomy, not tight, well defined. The variable tuning
can give you more control over the bass response and allow you tighten
up the sub and give you a more musical response. The main thing is
making sure you place that well within the room. I would say that you
should be fine placing it in the front of the room, in the corner, and you
may even want to consider opening the door to let the deeper bass
move through a bit more and give you a more even response. The
VTF-2 Mk4 would be a good choice because it does give you a bit more
extension than the VTF-1, playing flat to 18 Hz instead of 25 Hz, to cover
more modern movies that are starting to give you more material in the
sub 20 Hz range. If you're planning on really turning it up quite a bit, you
can also consider the ULS-15 Mk2 as it would play significantly louder
and cleaner, but the VTF-1 Mk2 and VTF-2 Mk4 should be able to give
you quite a bit of output at your listening position. There are some other
potential benefits in going with the ULS-15 Mk2 over the VTF-2 Mk4. The
sealed sub has less of a roll off in the deeper bass so if you do get a lot
of room gain in the deeper bass, it is possible that the ULS-15 Mk2 may
be able to provide you a bit further extension than the VTF-2 Mk4.
So, one, I thought this was helpful information to share with future buyers and two, I'd be curious as to everyone's opinion on the VTF-2 MK4 vs the ULS-15 MK2, is the extra cost worth it, or if I'm going to send the money would you just go with the VTF3-MK5?

If 11x12x10 is the entire space - and not just a designated HT section of a much larger area - then you would be fine with the VTF-2. It should have no problem providing all the output and depth you are likely to need. But the key word there is "need", because then there's the other side of the coin; "want".

The ULS-15 would have more impact and can extend even lower, so if you're after the utmost then you might want to consider that one instead. To a large extent it would be overkill but having a lot in reserve can come in handy should you choose to push the volume, or if you want to feel the really deep stuff.

So are you saying the ULS-15 would be better suited for a larger area? I ask because I went with the VTF-3 Mk 5 for my ~11'x13'x8.5' area that isn't closed off, but part of a larger ~6-8,000cu' area.

I was afraid of that, which is why I asked. A subwoofer doesn't acknowledge anything other than physical barriers so it's going to try and fill that entire space, not just the section you designated for HT usage. No single unit of anything you're looking at will be able to accomplish that. To an extent you can mitigate the issue by having the sub pretty close to the seating area, but in the end it will still struggle when the source material gets demanding.

Sorry, I happen to be in a similar situation; it sounds like the OP's space will be enclosed.

In my space, the sub is corner-loaded, so it does a nice job in the space; I'm thinking of either getting a second, or moving to dual ULS-15s if they can extend lower together in the space.

I thought the mk5 can put out more than the ULS. Isn't the main difference between the two is the ULS is a sealed unit, so you get the performance difference that a sealed unit offers?

I suppose this is the case down to 20Hz (according to their graphs), however, I would imagine the space determines real-world performance. I'm just not sure how much of a difference a much larger space makes for the lower extension (even though we're tucked away in just a corner of this space)?

What I don't get is that HSU suggested the VTF series because "The variable tuning can give you more control over the bass response and allow you tighten up the sub and give you a more musical response," and then suggested the ULS as being the best option. Doesn't the ULS have less tuning options being sealed? What was HSU comparing the VTF to when they said variable tuning was better?

Another question, are there negatives to going with something like the VTF-15H MK2 in a small space like the OP's? I am thinking of starting my theater in an open space and then eventually moving to a smaller room.

I don't know the context of the discussion between the OP and HSU, so I can't speak to that, but in general the situation may not be as far off-base as it seems.

Except for the EQ settings, the ULS has few tuning options. The VTF, by contrast, has several more potential combinations; you can go from full-on output mode to ULS like sealed, with other configurations in between. That's probably what they meant by "control", the ability to configure it to taste. The recommendations they provided suggest the HSU rep may not have been aware of the true room dimensions though. If that's the case it would explain the confusion.

Other than aesthetics, which is different for everyone, there are no negatives to putting a large subwoofer in a smaller (enclosed) space. What you'll tend to find is the smaller room will 'boost' the subs output, so some type of EQ and/or room treatment becomes almost mandatory. A distinct advantage to that approach is you'll find a larger subwoofer won't struggle to provide sufficient output, so it can then use that 'excess' capacity to better handle dynamic swings in the source material. That's a huge bonus for those who favor accurate reproduction; having very audible variations between the most and least intense parts of a soundtrack becomes addicting. Once experienced, those subtle variations no longer seem inconsequential.

Except for the EQ settings, the ULS has few tuning options. The VTF, by contrast, has several more potential combinations; you can go from full-on output mode to ULS like sealed, with other configurations in between. That's probably what they meant by "control", the ability to configure it to taste. The recommendations they provided suggest the HSU rep may not have been aware of the true room dimensions though. If that's the case it would explain the confusion.




Other than aesthetics, which is different for everyone, there are no negatives to putting a large subwoofer in a smaller (enclosed) space. What you'll tend to find is the smaller room will 'boost' the subs output, so some type of EQ and/or room treatment becomes almost mandatory. A distinct advantage to that approach is you'll find a larger subwoofer won't struggle to provide sufficient output, so it can then use that 'excess' capacity to better handle dynamic swings in the source material. That's a huge bonus for those who favor accurate reproduction; having very audible variations between the most and least intense parts of a soundtrack becomes addicting. Once experienced, those subtle variations no longer seem inconsequential.
What do the room treatments control, volume or boominess? If it's volume, can't you just turn the subwoofer down? If it's boominess, then isn't that a negative impact?

The treatments help negate reflections and deleterious effects associated to how sound waves interact with the room itself. They're a passive system as opposed to EQ, which is active. Both have their own unique benefits and limitations.

I have just ordered a HSU VTF-15H MK2 to replace a Klipsch RW-12 I have been using in my dedicated HT (12x19 by 8,6 feet high soundproofed room).

According to REW, my Klipsch goes down to 28 Hz (-3) at the MLP, but the bass output is very uneven across the five seats (two rows) I have.

I hope the HSU will help with the bass (down to 20 Hz). I plan to use the Klipsch in the back of the room to help even the bass response from seat to seat.

I cannot wait to see what the HSU can do...

Looking to sell my VTF3-MK3 and need suggestions for shipping it. Anyone shipped one without the retail box? What did you do? Or shipped any other large subwoofer?

Got it. Going back to my original question though, aren't the treatments necessary in any size room, or is this something that is in greater need for the smaller closed room?

Pretty much every room. The really deep bass notes have a wavelength that is so long it would be darn near impossible to find a room where you weren't going to get some reflections. The smaller the room the more likely it will negatively influence the output.
