Unless you are playing them at extremely loud levels to the point of distortion, I don't see where a dedicated amp will give you much benefit vs the cost. I would look at a 100watt+ Denon receiver that has Audyssey XT. You can get one that has pre-outs if you ever decide to upgrade to an amp in the future but it seems like overkill to me. Onkyo's quality control really seems to have slipped in the last few years. Lots of HDMI board failures.

Dr Hsu

What are your setup recommendations for someone with dual VTF-15's?


MY room is 22.5 x 10.5 x 7.5 (LWH).
Currently I am running one port open EQ1, Q7, and volume at 9-oclock.

I am interested in the low end benefits of the sealed mode, but am quite happy with my outputs so far.


Thanks.

Try it you might like it. Sealed has the benefit of a more gradual rolloff.

The surround on my 15H looks like it has a wear pattern on it. Almost like a car audio sub that has been rubbing against a shirt or something. I thought it was dust at first but it doesn't wipe off. Then I thought it was touching the grill but that not the case. Anyone else?

post #3455 of 5101
Just checked both of mine and they have nothing like that. You think it has been rubbing up against the speaker cover somehow?

Of all the things about this sub, that huge piece sitting there like that isn't very attractive. I would love to have seen more of the driver on the front of the sub. I guess it would have cost more to redesign the face but maybe it should be redesigned.

Thats the thing is the cover doesn't rub on it. I used a flashlight from the bottom up to see. I have no idea. Perhaps Dr. HSU would know.

Yeah, he should. Send him an private message, call customer service tomorrow, or maybe he'll see this posting soon.

Has anyone went from a mirage BPS400 to the 15H? The mirage has dual 12's and is a sealed sub which I perfer.

I just got off the phone with Hsu and placed an order for my second 15h! They had a c-stock unit that had two small dings, but I'm fairly confident I can doctor them up so I saved a good bit of cash as well so the wife is a bit happier... If you can call it that lol. I tried my 15h with an Outlaw Plus that I had laying around and they played pretty well together evening out my room response, but the Plus fell short a bit below 20hz so I took it out of the equation when I sent my 4311 out for repair. I'm excited to get a second 15h in my room!

Just don't blame us when you have too much bass. Congrats.

For anyone who is interested I made a demo video tonight of my 15H. I have never seen one exactly like it on youtube so I thought this little demo would be quite "moving.' It took a long time for me to make a decision to spend 1k on a sub Ive never heard or seen before. Had I have seen a video like this I would have bought it sooner.

post #3463 of 5101
Nice video and yeah these things will find rattles or should I say create them fun huh ,I had to put two sided tape on my wife's what -nots to keep them from dancing off the shelves after having to replace one of them.
post #3464 of 5101
Nice! I have two in a room that I believe is smaller than yours. It was rough getting them under control.

I plan on getting a few pics up soon, everyone loves pics right! I have Sky fall in my que, but heard there's really only two scenes with good bass which is disappointing, but Im still a fan of all of the Bond movies.

Me either really but hey, it's something new that I haven't seen. I have to get back into watching movies for what they are and get past looking for ulf in them. Ya know, look past the couple grand we've put out in subage but still know that they are there should we need them.
post #3472 of 5101
Sweet Saints, as I am sure Prime will attest, dual same subs is a great thing! I will never go back to using a single subwoofer in the main system.

Biased Bond fan here, but I liked Skyfall a lot. Its got a lot of decent bass but only a few WOW scenes. But I like dynamic movies that aren't a 2 hour bang boom pow movie trailer. I also thought I detected a few scenes that went pretty low frequency wise at low levels to set the mood. Might bust out the RTA and see next viewing.

Hello fellow home theater enthusiasts! Although this is my first time posting, I have been following this thread for quite some time now. Right now I am in the process of building my home theater and my next purchase is the subwoofer. In doing my research, it didn't take long before I was sold onto the VTF-15. Besides the glowing reviews and the personal input by Dr. Hsu himself, I was most impressed by the dedicated fellowship here in this thread and how supportive everyone has been. Well, not to carry-on with the praise, I actually did come here to post a question to everybody.

I have yet to purchase a subwoofer as I previously mentioned, and I am just waiting on the funds to come together before proudly joining the Hsu family, but wanted to get everyone's input on how the sub handles ultra-low frequencies. I have ventured to the other AVS threads until they were coming out of my ears with other members raving about crash scenes from Flight of the Phoenix and monster scenes from Cloverfield and other scenes from War of the Worlds and Tron, etc. I have no doubt that this sub is more than capable but saw on the HSU website that this sub is tuned to go down to 16 Hz, but does room characteristics come into play or is it tuned only to 16 Hz but will more than handle and play lower frequencies. Just wanted to get your thoughts.

Thanks again everyone in helping someone like me who had no idea where to start in the subwoofer market to find a home here!

The lowest tune for the 15H is 16 Hz. It does go lower but will not do so at very high SPL. As with any vented subwoofer, the output from the port below the port tuning will rapidly become out of phase with the output from the woofer. To get very high output below 16 Hz is usually not very practical - you need a large number of very large subwoofers to achieve this. You need very high SPL at such low frequencies to hear or feel it, even higher than at 16 or 20 Hz, and it gets a lot harder to get high SPL at these frequencies. The only subwoofer that can put out high SPL at such low frequencies is the Eminent Technology rotary subwoofer. For the majority of listeners, the 15H is quite sufficient! biggrin.gif

Get a 15H, find the place in your theater or listening room where it will give you the best bass response, set it up with whatever room correction method (s) you use, leave one of the vents plugged, leave it on EQ1, Q to .3, sit back and relax.

Got it?

WOW, been watching those Dodge Dart commercials too much.

Almost forgot, when you go to place your order forget about the finance guy.....lol.

Thank you both Dr. Hsu and Prime for your quick responses. I have heard this time and time again so it must be true. Set it up, sit back, and enjoy your movies. I am seeing these posts online of charts with frequencies from 2 - 10 Hz so it just go me thinking is all. I watched Terminator Salvation today with all of the bass management going to my two front towers. I thought the woofers were going to pop out with all of the heavy sub-frequencies taking place. It sounded good but only made the itch worse if you know what I mean!?
post #3478 of 5101
I won't blow smoke up your behind. There are a lot of good options out there as far as subs go. I'm sure you've seen them if you've spent a few mins checking the different threads in this forum. A great many of them will dip down to the levels the 15H will go and some a little lower but for the price, I don't think you're going to do much better anywhere. I own dual 15H's and they have treated me well.
post #3479 of 5101
I’m waiting on carpeting so it will need to be moved again but the sub is out of storage and in its new home; the enclosure really amplifies it. It’s interesting to run a song with a bass beat, tweak the levels on the sub to what you think is good and roll it back under the rack only to realize it’s too much.

That is a nice job of hiding the equipment! You always want to fine tune after you get the sub in the final position.
