It's a basement that opens up to upstairs from the back of the room. Not sealed, unfortunately. The VTF-15H is up front, about 13' from the LP. The VTF-3 MK3 is nearfield, used as an end table at the LP. Woofer pointed into the chair.

Finally made my decision and ordered a VTF-15H... can't wait for it to be delivered....

Call me crazy, but I just received a replacement driver (my other one was leaking air pretty bad) and I'm still getting a rather substantial whispering/whistling noise at 25hz. Not nearly as bad as it was, but it's definitely still there.

I moved my hand around the outer edge of the driver to see if I could feel any air and I don't believe it's leaky (I felt some air but I'm pretty sure it was from the cone moving).

Am I crazy or is this normal? You can here it just a little bit at 31.5hz and then not at all from there up. 20hz is also not too bad, but still slightly noticeable.

Btw, this is a 2.3

At the listening position or at the port?

Rather audible at both, but obviously more significant at the port.

Another factor is how many knick-knacks your wife has that will rattle. The first time I cranked up a "real" sub in our living room there was stuff rattling I never even knew we had. Wife came home and there were all kinds of paintings, wall hangings, candle holders etc. laying down on the carpet so I could hear the bass itself instead of the rattles.

Different house, different setup and just putting the home theater stuff back together. With very minimal excursion on a sealed 15" (volume and equipment wise I'm just getting started) there are already all sorts of rattles...here we go again...pass the blue-tack please.

Your going to have smile on your face once you hear the big guy in action....

Anyone?

I ordered the HSU VTF-3 MK3. I should have it Wednesday. I will be sure to post my impressions.

Lol, that sounds familiar. Nothing like walking around the room with a screwdriver trying to tighten rattling vents, lights, etc. Good times.

Does anyone run Audyssey calibration with the sub in max-extension mode, and and then flip it back to max-output mode for playback?

I prefer max-ouput mode for the extra headroom, but Audyssey seems to flatten it too much. This method worked well with standard Audyssey on my last receiver, but not so sure with the MultEQ XT32.

Anyone else ever experimented with these modes on Audyssey?

I love my STF-2, have had it for about a year and its an amazing sub but lately im finding myself wanting more and more bass, especially listening to lower frequency based music (such as dubstep and electronic music).

I have been thinking of either purchasing a second STF-2 or maybe upgrading to a VTF-2 for the lower extension level it provides over the STF-2.

Can anyone recommend another HSU sub for pure music listening? Im really looking towards either the VTF-2 or maybe something a little better as i have read that the STF-2 and VTF-2 are pretty similar.

If it is the original VTF-2(very old model) yes they sound similar.

However, if you are comparing the STF-2 to the VTF-2 MK3, you have two different animals there. Starting with the different driver size, cabinet, and amp.

Caci is right, the VTF2 is a significant step up from the STF2. The old VTF2 is a lot like the STF2, but the new VTF2 is a lot like the old VTF3. Big difference. You can compare them with Hsu's comparison chart.

I have an STF-2 in my wifes t.v room and love it. If you decide to sell it, please let me know? I'm considering running duals.

A couple of weeks ago somebody posted that The Flight of the Phoenix (2004) BD has incredible LFE and can let a Hsu sub really strut its stuff. As I remembered how bad the film was dramatically, I hadn't seen it since it first came out on DVD over 5 years ago but decided to rent the BD and check out the HD sound track. I'm glad I did. My VTF-3.3 Turbo had my HT room shaking from the beginning of The Flight of the Phoenix until the end. In fact, the over all sound design was brilliant. The background music was beautiful and the various storms, explosions, gunshots, and airplane sounds were riveting. It's a shame all of that was wasted on such a dumb movie. Still, if you have an excellent to outstanding HT audio setup, check the BD of this movie out, you won't regret it.

I was in a similar situation a month ago. I got VTF-15H and moved STF-2 upstairs for a smaller room. World of difference. If you can make the switch, I am sure you will love it. However, I should say that my usage is 50/50 Music/HT

Man I wish I could locate two turbos for my 3.3's

I've got a question for you guys who know what you're doing. Can I put together a decent Home Theatre system with the following that I have available to me:

A pair of HSU HRSU 10's powered by an Adcom GFA-555.
5 - B&W Rock Solid Monitors

The room is 12x20 and I'm using a new Pioneer VSX-1020-K receiver.

Or would I be better off with a Definitive Technology Pro Cinema 800 setup?

Yeah, its a shame that most of the best bass movies are awful dramatically. I don't care how good the bass is in Transformers 2, I am not watching it! Or the Last Airbender, or Pulse, or Percy Jackson, or whatever. Watching Terminator Salvation just broke my heart, as long time fan of the terminator movies, oh god. Flight was just barely watchable, although it mostly just reminds how good the original was, and same thing goes to a lesser extent with War of the Worlds. On the other hand, How to Train Your Dragon was a decent movie as well as being a bass fest. It's a good thing I bought my Hsu's mostly for music rather than movies, honestly, with my movies tastes, its not even worth owning an expensive sub for movies. In the end, it's all about personal preferences though, so this is just my irrelevant little rant!

Dalumberjack, I used to have a turbo, I found it didn't make much of a difference with my VTF3 mk3, aside from making it look awkward, so I sold it. I suspect those things were meant more for the VTF3 HO, in fact, if I remember correctly, Ilkas tests show they didn't do much for the VTF3 MK3s performance either. I wouldn't worry about it if I were you.

Thanks Shadyj for the info.

Just want to say I have been dealing with Pete from HSU about my amp going bad (exploding!). Pete has been awesome in getting back to me. They got my amp Friday (1-14-11) and they hope to have a new one sent out tomorrow. I am hoping this all works out and I get this new amp in and installed before my surgery this Friday. Would like to enjoy my subs while I recover.

+1 for HSU technical support.

PS: Could anyone take a look at my post (page 121) and tell me what exploded on the amp. Is that thing called a capacitor? And could someone tell me why it would have exploded?

Well, if I think back to building circuit boards from radio shack, a capacitor is the cylinder shaped object that holds a charge. Usually when mine go bad, they usually bulge out the top.

But trust me, there are many more knowledgeable people here on the subject.

I just bit the bullet after going cross-eyed reading all the posts in this thread. There's VTF3 MK3 on the way with my name on it. I thought that I was going to be satisfied with less expensive sub. No understand that I've been living with a Dayton 10" Titanic for a very long time... I thought that the BIC PL200 would be the ticket. Unfortunately, that was not to be. I'm limited in sub location and size. Where the Dayton clipped, the PL200 sounded muddy and I just couldn't get it to perform the way I wanted. I also seemed to forget a lesson (that I thought was learned) and don't try and be cheap. So... I'm looking forward to getting a sub that compliments the rest of my system. I think that the HSU will have plenty of head room and can't wait to replay WoTW. Pete was a great help, so I'm already impressed with the customer support. I know what I'll be doing this coming weekend! I'll let y'all know what these old, uneducated ears think after I get it setup...

I think I better put my wallet under house arrest for a while.

I hope you arent TOO stretched for room, the VTF 3.3 is a BIG sub...It takes a good hour or two to really tune the 3.3 the way it sounds best in your room but once you get it right it sounds amazing...

Very good points squeeks. That's what impressed me with the conversation with Pete! Thed spot where the current sub resides is where it will have to go and there is enough room for moving it around. I plan on tweaking the system all weekend. I just wish that I had done this first off...

make sure to play with the test /calibration cd when you get it, its taped to the side of the box with the packing list, the first 5 tracks are pieces of classical music, and the last set of tracks are various test tones. There is summary page included with the disk, be sure to head the warnings as the first track gets really deep, really loud, really fast.

Just got the email that my amp was shipped out by HSU and should hopefully be here on Thursday! YAY! I asked what happened to the amp and the response I got was "it must have been bad"

I'm to curious to take that as an answer lol. So, if anyone after looking at these two pics can tell me what this is and possibly why it exploded, I'd love to hear it. Just like to learn random stuff.

PS: Sorry for the large pictures. Don't know how to thumb nail size them with photobucket

Every time I see those all I can say is wow... I can't offer any reason as to why it happened, but out of curiosity, do you use speaker level inputs?

I must have missed the link to the photos when you first posted -- or too busy watching football. That definitely looks like a capacitor. As to why it fried, that's anyone's guess. Power fluctuation? Old age? Youth and infant mortality? Manufacturing defect? Who knows.
