Fun getting a new toy, isn't it? Glad to hear you are enjoying the VTF-3 and Tron Legacy will certainly give it a workout. The new Wonder Woman is also a good bass flick to check out.

I have carpet over concrete. Kind of disappointed that I will lose out on some tactile feel.

In my situation are some sort of spikes beneficial to anchor the sub to the concrete?

Anyone pair these subs with buttkickers? Worth it?

Properly set up and integrated Buttkickers are most certainly worth it! They provide a wonderful low end tactile response ... been using them for several years now with my VTF-MK4 and an Energy S12.3. Highly recommended!

Well I've had this puppy (VTF-15H MK2) since February and I have to report that I am totally in love with this thing. My old cheap sub had a lot of punch at one frequency which made me doubt my Hsu at first. But the frequency range and power of this sub is pretty phenomenal.

I may end up with another one for Christmas. Maybe I'll "return" it and get the DualDrive! hahaha

About the only thing I can think of that would be an upgrade from this is the SVS PB16-Ultra....but for the price I seriously doubt that it would be better than 2 VTF-15H's, and it costs considerably more than 2 HSU's.

I'm not a super audiophile like most guys on here but I know enough about AV equipment and know WHEN to ask questions and the reason I purchased the Auralex Gramma is because I felt that the sound from the sub was somewhat muffled. When I added the Great Gramma, I felt that the bass now spread out evenly across the floor. Again this is just my opinion. And I've experienced it on both carpeted floors and most recently...hard-wood floors. The Outlaw did have spikes but it also came with mini-coasters to put the spikes on, but to have it on the Gramma gave it more height.

This is all just based on my feel from the ears, nothing scientific. Let's just say that it doesn't HURT to have it but if people are on a budget this is more a "luxury" item, than a necessity.

P.S. - The sub I have is the Outlaw LFM-1 EX. So I was on this forum as a comparison to see how the HSU subs are and a potential replacement along with Rythmik (sp?)

Hi - long time member at AVS, but new to HSU. I have a sweet new VTF-15 coming on Friday (replacing an old SVS PC-Ultra - circa 2005).

Any advice for how to get this sub downstairs? I have a hand truck and bungee cords - or should I rent an appliance dolly?

Any unpacking advice? I'm not a kid anymore - I'm 57 and kind of realize I need to start paying attention to things like this before I do something dumb and hurt my back?

I attended a SVS PB-16 "kickoff" demo at a local Philadephia retailer. SVS was present along with about 50 customers. I decided that night that I needed to upgrade from SVS. To my wife and me, the PB-16 sounded muddy and underwhelming. Of course it could've been the setup, but come on - this was a well advertised demo geared to selling product. We ended up leaving early and I've been looking for a sub ever since. The winner was the HSU VTF-15, which I'll have on Friday.

Being that I move subwoofers around all the time maybe I can provide some insight...

Any decent hand truck will suffice for what you need to do, provided the sub is secured properly. Bungee cords stretch and have play so they're generally not a good choice. Rope would be better, or a ratchet strap provided you don't over-tighten it. I would suggest you wrap the sub in something like a blanket or thick towel so as not to scratch the finish. Move down the steps slowly and methodically; speed is not your ally here. Plan first, move second. Invite a buddy over to help. Offer him a couple of cold ones - after you get the sub downstairs - and things will be much easier.

If you take yourself too seriously, expect me to do the exact opposite

Yeah, I'm on the wrong side of 50 by a few years and have to be a little more careful now too.

When I got mine, I put the box on a soft blanket and pulled it across the living room floor. Then I just slid the box down the carpeted steps to the basement. The box is HUGE so it was really easy to push against it while going down the stairs. I figured I'd have the wife there so that if it got away from me, she could pull my dead body out from under the box at the bottom of the stairs.

Well, it arrived today and I got it downstairs by myself. The advice about using rope to secure it to my hand truck was PERFECT. Thanks, @JimWilson !

First demo was my John Mayer Blu-Ray - "Vultures" is my go-to track, and it sounded great.

Next up, re-running Dirac

Glad it worked out for you. One of the larger/heavier subs I reviewed was the XTZ SUB 3X12. That was a lot of fun to repack by myself...

Just got my 4 ULS-15 MK2's. Deploying them to the 4 corners of my room.

They were packed very well, and no damage noted.

I'll be using a balanced miniDSP 2x4 and likely Andy's MSO software to calibrate them.

Good times.

Good times.
I am considering using 4 HSU subwoofers (their best, either sealed or vented....not sure yet which way to go) in my living room setup that we will have in our new house next year. I have been considering other options like 2 larger more powerful subs with 18 inch drivers, but then placement options becomes limited. I would hate to get 5000 dollars of subs in place to find out that those two spots lead to unfixable responses issues. So I am considering 4 subs at the corners of the listening area in the hopes of getting a better overall response. I would be placing the front 2 equidistant from MLP and the back 2 also equidistant from MLP. I would have a receiver with Audyssey and dual independent sub outs. So front 2 subs would run off one sub out and back 2 subs would run off second sub out.

I know it is hard to predict with great accuracy how smooth Audyssey could get the response with my proposed setup, but I have attached some pictures. The house is 2 floors and 3100 square feet. Any thoughts would be greatly appreciated.

The 4 corners of "the listening area" and the 4 corners of a rectangular room are 2 very different things. Identical subs in the 4 corners of rectangular rooms has a bit of research to look at that shows a reasonable chance that the outcome can be very amenable to room EQ.

Your situation is impossible to say. I would say that the positions you've indicated may very well need to be modified to get the best response. I would recommend optimizing the combined sub response prior to using room EQ. The goal is to minimize all nulls at the listening positions, and to have the peaks the same at all listening positions. This optimizes the response for global room EQ solutions like Audyssey. I recommend the following software to do this, but it requires a miniDSP.

I think you're going to enjoy the ULS. I reviewed the MK2 a few years back and was quite impressed at what you got for the money.

Yes, long time no talk. Doing well, ty.

The sealed 15's are a bit small in displacement for my tastes, but I do think that corner loading 4 of them will give me the clean reference level output into the high teens(maybe even low teens) that I'm looking for. I am looking to get the best response across all my listening positions, so I went from 2 dual 18" JTR's to these 4 15's. I just couldn't get those monster JTR's where they needed to be to optimize the response the way I wanted it, and adding two more was just out of the question in my room.

My goal was to get the smallest subs I possibly could to achieve that goal. I would rather have a little less output, but a much better FR.

I've got a balanced miniDSP 2x4 and I'm going to use the MSO software to optimize them before I EQ them with Anthem's ARC room correction.

I'm a bit excited about it since I'm expecting stellar results from that combo.

Fancy running into a JBL M2 guy here . But I went with a quad set of ULS-15 Mk 2s for similar reasons. I had thought about swapping my old ULS-15 Mk I pair for something in the Seaton line, but considering that I live in a condo, and that I really didn't need to rock the house six floors down at 10 Hz or lower for my movie tastes, I ultimately decided that four 15" subs were a better option than two Seaton Submersives, or waiting for Mark Seaton to produce four of his "half Submersives" in time. I ultimately wound up spending the savings on a better PJ (JVC RS600 on closeout).


It ultimately worked for me...with 1/4 & 3/4 front and rear wall placement, I was able to get smooth, non-distorted output with non-destructive ringing from about 15 Hz to about 90 Hz, where my mains took over. I had tried corner placement, but I had to fudge it as one corner of my room had a door and I consequently didn't get good results. In my current placement, I have consistent enough output for all three seating positions (three seats in a sofa's single row) that room EQ was really more icing on the cake to bring down a few remaining peaks in that range.


Even if you corner load and use EQ1 mode, I'm not sure that you'll wind up with useful low teens output unless you really get lucky. However, from personal experience I think you can realistically hit 16 Hz with clean output and low distortion, especially if you're not looking to actually listen at 85 db reference levels and 105 db peaks.

I would add having bass decay down -20 db from your response, at least at 450 ms, to the list as well. You would want an Omnimic or better yet, REW, to measure that.

Good choice, as long as your seating positions aren't too closely together. MSO doesn't work well if you just want to optimize one seat and have to do tightly bunched measuring positions (a minimum of three, as per Andy, and I think you'd want a minimum of 1' apart from what I've read on the MSO thread).

I hope you can. The HSU subs are underrated compared to flashier brands on AVS IMO, but there's a few serious AVSers I know that have them and use them productively (although most of the ones I'm familiar with are still using the Mk 1s as they've been happy for a few years). It's all about the multiples.

I just couldn't get those monster JTR's where they needed to be to optimize the response the way I wanted it, and adding two more was just out of the question in my room.

Fancy running into a JBL M2 guy here . But I went with a quad set of ULS-15 Mk 2s for similar reasons. I had thought about swapping my old ULS-15 Mk I pair for something in the Seaton line, but considering that I live in a condo, and that I really didn't need to rock the house six floors down at 10 Hz or lower for my movie tastes, I ultimately decided that four 15" subs were a better option than two Seaton Submersives, or waiting for Mark Seaton to produce four of his "half Submersives" in time. I ultimately wound up spending the savings on a better PJ (JVC RS600 on closeout).


It ultimately worked for me...with 1/4 & 3/4 front and rear wall placement, I was able to get smooth, non-distorted output with non-destructive ringing from about 15 Hz to about 90 Hz, where my mains took over. I had tried corner placement, but I had to fudge it as one corner of my room had a door and I consequently didn't get good results. In my current placement, I have consistent enough output for all three seating positions (three seats in a sofa's single row) that room EQ was really more icing on the cake to bring down a few remaining peaks in that range.


Even if you corner load and use EQ1 mode, I'm not sure that you'll wind up with useful low teens output unless you really get lucky. However, from personal experience I think you can realistically hit 16 Hz with clean output and low distortion, especially if you're not looking to actually listen at 85 db reference levels and 105 db peaks.

Based on prior experience with corner loaded subs in this room, I do think I'll get low teen numbers. Reference in high teens without a doubt.

The difference between mid wall and corners is pretty dramatic from a subjective perspective in my experience (and measured, but subjective seems more).

As to the M2's and being in an HSU sub club, I've always been about getting the greatest value in audio, it just so happens that the M2's represent that to me. JTR too, I just wish Jeff made more WAF options .
