I have put the HO with turbo on Audiogon if anyone is interested.

Hi, I have had my vtf2-mk3 sub since 9/2008.

It has started to rattle even at low levels. I noticed if I take my hand and push down on the top of the sub, it stops the rattling.

What's my warranty like and do you have any recommendations?

when you say push on the top of the sub, do you mean the cabinet? Not the driver, right? Maybe one of the panels in the cabinet came loose? I would suggest doing a bit more investigating. Even if you had warranty left, it's not cheap shipping a big heavy sub back and forth.

I currently have a vtf3.3. I am looking to add a subwoofer. Should I add a f15 or another 3.3. I guess my question really is can two different subs match up ok like this? Or does it make sense to sell the 3.3 and buy two f15's? My room is 25 x 15 with open areas to both sides. I trying to even out the levels and give it a little extra. The 3.3 has been a really nice sub.

Let me know what you think. Thank you.

Yes, on the cabinet. I don't know what else to do, can you advise?
I figure I could rest a 5lb weight on top of a folded towel, but that probably
won't last very long.

Sell the VTf 3, get the returning customer discount buying a VTf-15H, and call me in the morning...

Whatever you do, don't mix...IMHO

cacihome, there's a returning customer discount? I've returned at least four times in 5 years, didn't know there was a discount.

Ehhh.Oopss..hahahaha
Sorry HSU if I got you into trouble...HAHHHAHHA

Legairre,

That's what I think...I mean. I even put my subwoofers in income tax forms too since you know, in our case, they are every year common expenses...HAHAA

No proble cacihome, I thought the returning customer program was gone along time ago. Thought maybe it, came back and I missed it.

I wouldn't try to match a VTF3 with a f15. As nice as a VTF3 is, I have a feeling the F15 will be a bit sharper (I hate saying this in the Hsu thread), and they would be too different to integrate well with each other. I would go with either two VTF3s, two F15s, or make the stretch to a dual ULS-15 setup.

do some investigation. If that panel is loose there may be air leaks, may be able to check for that with a section of tissue paper along the seams when running at good volume level. Also you might be able to put your hand along the edges/seams and fell what's flexing, if that's what it is. The next step would be (carefully) taking out the driver and taking a look inside. The remedy for this could end up being 13 cents worth of wood glue...or it could be more serious than that.

For clarity I am talking about new Hsu 15's. I would either add a new Hsu f15 to the 3.3 or add another 3.3 or sell the 3.3 and buy 2 new Hsu f15's. The only other subs I would look at are svs ultra 13's. Adding another vtf3.3 would be the easiest, but I don't want to always wonder what I am missing! I really wonder how much more I would gain. The single 3.3 does a really nice job now and I have zero complaints. I need to just stop following these threads after I buy something so I don't want it!

Any advice is appreciated. Thank you.

get either a new VTF15 or a used 3.3. No sense in a new 3.3, as a lot of folks are upgrading, deals to be had out there.

Oh, I thought you were talking about the Rythmik F15. Yeah, I think a VTF-15H would go well with a VTF3 depending on how you set it up. If you used the VTF3 near-field like an endtable, and the VTF-15H in the corner or something like that. If you can not arrange that type of setup, I would just sell the VTF3 and get a couple VTF-15H subs. The VTF-15H looks to be so much more powerful than a VTF3 that it wouldn't be worth it to try to run them as equals. That would either restrict the VTF-15H from achieving anywhere near it's potential, or push the VTF3 past its limits. It would probably be best to consult Hsu's customer service about a move like trying to integrate them together.

really depends how you set the gains. You can always dial down the sub that has less power handling. Or, find a way to play to it's strength using placement or tuning.

Thanks, will check it out this weekend. I hope I don't have to open it up.

'tis what I do with fairly decent results. Though I moved the 3.3 from endtable to a few feet away and I like it better.

The original plan was to sell the 3.3, but I'm having a hard time letting it go

IF you do, be very carefull not to slip with the screwdriver/drill etc. and put a hole in the cone or surround. "I know a guy" that did that once...

So you added the vtf15 with the 3.3? I have a hard time getting rid of good equipment, but I have the itch to upgrade. Have you done any experimentation like turning the 3.3 off to see how it adds/detracts front the overall sound? I wish the Hsu factory was in Indiana!

I've been doing more playing/testing than listening. I wasn't as enthusiastic as some of the new 15H owners when I first got it, but I finally have them both dialed in nicely. I've done listening tests as well as graphed the response and the 3.3 definitely adds. The response is flatter and it fills the room a lot nicer with both.

I can see myself picking up a second 15H eventually, and even then I doubt I'd get rid of the 3.3. If you're looking to upgrade, I'd recommend adding not replacing. Multiple subs are king. I don't think you can lose with another 3.3 or 15H.

Huh. I wonder if I could get my health insurance to pay for a couple subwoofers.

I think I'll start putting large change jars in stores around the hood...a Sub Donation For Stu!

Thank you. That is precisely the input I was looking for.

Dumb question -

with a pioneer 1120k, I am running a mono rca cable from the subwoofer preout to my VTF-2 mk3. Am I correct in assuming this should go to the top input (Sub in/Left)? Or do I need a mono-LR adapter to get the right input as well?

I'm still trying to work through getting my sub sounding integrated into my system..

You are correct.

So I need a mono-LR rca connector?

I cannot quite figure out your post

Just a single cable into the left input. Did you try some of my recommendations? Also I saw your other post. There is a link for test tones on this page here that I use, plus alot of other good infomation and tools.

I'm going from a Velodyne DEQ-15r to a VTF-15h. Velodyne recommends a splitter into both low level inputs(L+R) for a stronger signal to sub amp,and as I understand it,HSU doesn't. So, I have two questions;why two inputs if I'm only to use one,and what would happen if I split the signal into both L and R?

Nothing. You will boost the signal to the sub by using a Y adapter and subsequently may need to turn down the gain on the amp.

Using a splitter to the two inputs can help with a subwoofer that goes into standby while playing at low levels. Another solution is connect the interconnect to the left input and then leave the amp in the "ON" position.

If using the ULS-15s wireless function, you must connect both the left and right inputs to the transmitter.

Wsky answered your question quite well but let me answer it this way. I own Velodyne subs and I also use the Y splitter into the subs because A) that is recommended by Velodyne and B) because of the difference in the amplifiers used by Velodyne VS the Bash Amps used by HSU. Since the amp in the HSUs are more sensitive they do not require the Y splitter. So my two Velos have the Y splitter into both inputs and my two ULS-15s, which are hard wired only use the Left input.
