If the size doesn't bother you, I would go for the VTF3 mk5. The ULS is a great sub, but it is more expensive and it does not offer as much output. It's for situations where there is a real WAF and you don't need extreme loudness levels.

The dashed line is a beam, held up by the pillar (black square), and my rear surrounds are ceiling mounted directly in front of the door to the unfinished space. All windows have the blackout honeycomb type shades. Only the bottom few stairs are open to the staircase, so not totally walled off. 8.5' ceiling.

My sub placement options are numbered in order of preference, with my current sub at the #1 position. I believe I can squeeze the mk5hp in the same spot, or will the ULS-15 give me what I'm looking for (for now)? Like I said, I will most likely add in a second of whatever I go with in the future. Any insight would be greatly appreciated!
If you can put an mk5hp in spot by the couch you'd have chest thumping bass. It'd be unreal. Spots by the tv would still be excellent.

I'll see if I can draw up a sketch of our layout to illustrate my placement options.

The ULS-15 will extend a little deeper and is pretty linear. You will need 2+ for large rooms.

For music listening only, I think the ULS-15 would be nearly as good and about the same price, yet smaller. If you plan on watching movies and want solid output without compression, again, it would take FOUR ULS-15's to match the output of ONE VTF15.2 at 20Hz. I know what I would go with.

Thanks everyone, I'm going to try the VTF-3 MK5 HP for now; unfortunately, the VTF15.2 is just too beastly for this space, no matter the placement. I suspect I'll be blown away by the difference, even though I was able to get my rw10d dialed in to the "t" for this space. I'll be sure to post back my impressions

I just ordered a VTF-3 Mk5 HP last week and from what I can see, I'm gonna like it. I also was going to order the pb-2000 but after looking at everything I said, lets just get the best we can and I did. No looking back now. You made a good decision on it.

Newb question, how can the VTF15.2 output have so much more output at 20Hz, when the chart for it shows 89-93 dBSPL at 20 Hz and the ULS15 shows 90-94 sBSPL at the same frequency?

The chart isn't showing maximum output sweeps, it is only showing the basic response. If you want to know how loud these subs get, you should be looking at the CEA 2010 measurements. At 20 Hz, the VTF15h mk2 has an almost 10 dB advantage over the ULS-15. This is slightly more than 3x as powerful.

Just got my HSU!! W O W it's HUGE!!! But I love it so far, although I've only had it a couple of hours. I set it up and played the demo disc they packed with it and the very 1st song I knew I had something special. Felt it through the couch LOL... I'm going to try to put it in front of the room and see how that goes.

Hello HSU owners, as I am close to finishing my small HT ( 1500 cubic ft space) I have a a subwoofer dilemma. If you check my setup( link in the signature below),you will see I have no separate subs except for built in Supercube1's in the Def Tech BP7001 towers. I have just installed back wall bass trap and some other acoustical panels which have helped overall sound tremendously ( best used 300$ ever for HT), I am generally happy with amount of mid bass I get , would like some extension in to 10-20 Hz region. Space is at premium, have room for sub that is not higher then 22" and not deeper then 23 in front of the screen and then space for 19" wide and 24 deep in the back, just by the riser. You can see my space in the signature link.

What would be your suggestion? I am comparing options with HSU, SVS, Rhythmic, PSA or vintage Def Techs.

Change is the only constant.

My HT: http://www.avsforum.com/forum/19-ded...l#post32691273

I would be looking at a couple of Hsu ULS-15s. They fit your dimensions and ultra deep bass is their forte. You can get more bass at 20 Hz out of a ported sub, but a sealed will give you output at 10 Hz, which no ported sub can do. What distinguishes the ULS from other sealed 15"s is its XBL^2 driver. It may not have more maximum headroom than other 15"s, but within its dynamic range it will play cleaner and with greater linearity, so for loudness levels below its xmax it will play with lower distortion and totally neutral response.

Just bought a VTF-2 Mk 4. A little worried about the reports of amps going bad in a few years, but still very jazzed by the flexibility and performance. Seeing 25Hz, 20Hz and 16Hz actually working in my home is thrilling.

Does anyone know if there's a post or discussion in this thread about what to listen for in the Hsu/BAS test CD musical selections? First track, the Saint-Saens Organ Symphony excerpt, no brainer, but for the second...? TIA.

Addendum: Track 1, engineer (or someone) mentions a clean 16Hz subharmonic from the organ. Various subharmonic tones heard in this track. Track 2, low E-flat from the organ at the finale. Track 5, notes mention you may hear the door open and close as trumpeters rejoin. But ... subwoofer indications? Tracks 3, 4, I don't see any suggestion of what to listen for from the subwoofer.

Modest "theater": Samsung UN40ES6150, Panasonic BDT210, Yamaha RXV775. Bose 401 mains, 301 Series III surrounds, Yamaha NS-C444 center, Hsu VTF-2 Mk4.

My cd came with a piece of paper that had a little writeup on each track.

Thanks, guys. I do have the slip, my apologies for being unclear. I see suggestions for Track 1 and 2 for what to listen for from the subwoofer.[1] I was curious about the others (3 - 5). I've used the test tones to set volume trim and crossover, actually track 22 (sweep from 200Hz to 80Hz) has identified a little problem around 120-130HZ in my mains, so I've boosted my crossover up a bit to use the VTF-2's range. So far,... splendid improvement.

I'm trying to find my copy of the Delos Engineer's Choice CD, which didn't so much have hi-fi demo tracks, but examples of recording techniques and venues. Some really great, naturalistic recordings. It's in a box somewhere. Derp.

[1] 1: Organ produces subharmonic tones, down to 16Hz. 2: Low E-flat form the organ at the finale.

So I have had my VTF-2 MK4 for a few weeks and was starting to get slightly concerned. I had a buzz at certain frequencies but couldn't pin it down. I got a Subdude HT and that helped clean things up on my tile floor, but that buzz still came up every once in a while. I finally nailed it down "literally". The old Victrola next to my subwoofer has 3 rear panels that resonate perfectly at somewhere between 60 - 80 HZ. I inserted a few nails along the edge of the offending panels and the buzz is gone. Holy cow this Hsu ROCKS!!!

Hey there...

So I have had the VTF2-Mk2 for a few years now and it sounds (feels) great in my room. Of course I would love to splurge and get the latest and greatest upgrade but money is tight. I found someone selling the same VTF2-MK2 for $350 locally, wondering if I should grab it and have duals...or save my pennies for VTF15's down the road.

The VTF15h subs will have a LOT more output, and they will dig deeper too. I would go for the VTF15h or the VTF3 mk5. Also, I think 350 is a bit high for an older sub like that. It doesn't strike me as a great deal, I would pass on that.

Maybe you could talk that party down... Dual subs are a oft-recommended configuration.... How old is your VTF-2 Mk 2?

Also bear in mind that the VTF-2 Mk2 is closer in performance to our VTF-1 Mk2.
