Axiom Home Page Forums General Discussion Advice from Axiom Owners SVS? or . . .

I'm close to pulling the trigger on a a SVS 25-31 pi. Do I need this to replace a noisy JBL PB12 or are there other products I should be looking at?

I use two Hsu VTF-3 MKII subs that nearly bring the house down and my theaters is in the basement (carpet over poured concrete). A single VTF-3 is 350w, 18Hz and can hit 16Hz. A single VTF3 pressurizes my 13x24 room really nice. I won't even say what happens when both are going. There really should be a law against running two of these in a room the size of mine.

What size is your room and what SPL do you intend to listen at? Also what kind of extension do you need?

My room is 12x20 with 8 ft ceilings. It will be used mainly for HT backing up a pair of m22s.

Actually, Legairre, there ARE laws; But they aren't written in legalese.

They're written in medical texts

And the laws get even more severe when you toss in your surround subs

But,........ain't it fun

I would think the Hsu Vtf 3mk2 would certainly outperform the Svs pci 25 31.It is also a bit more $$$$ than the Svs too.I would expect the Hsu Vtf 2mk2 to be at the same performance level of that particular Svs sub.The Vtf Mk 2 is bit cheaper too.

hey legairre,how are you?how are the hsus compared to the velodynes i had.i know its been a while since you were here and are two totaly different rooms,but recall as best as you can -my room was 24x24.....im gonna get up there and hear that system,i swear im gonna,its just been such a busy year that in my few minutes of spare time i get here and there i just sit back and wonder what it would be like to have some...........spare time? see ya...ron

HSU STF-3. It's upgradeable once the turbocharger comes out, too.

The

Forgive me if I'm skeptical, but a turbocharged amplified speaker sounds just a tad gimmicky.

It's not a real turbo or anything that adds any kind of forced induction into the sub. It's just a pair of "U" shaped tubes that extend the port area allowing for lower extension of the sub. Hsu uses the term turbo becuase it increases performance.

Snce you've already looked at the SVS 25-31pci I'm assuming your looking to spend around $500-$600? If you don't mind a box sub there's alaso the SVS PB12-ISD(22Hz anechoic extension with 18hz in-room frequency response) for $599.

What is your price range?

$500-$550 is the limit of my budget for a sub. The reason I was thinking about the SVS is because it's a tube style and wouldn't take up much room. I was also thinking of the Infinity csw10, which is marked down to $599. It has a 650 watt amp. I don't know if it's any good, but that's alot of amp. I think any sub would be ok for me. I actually like my JBL, but it appears it's days are numbered. I've only had 2 subs, a really rotten KLH and the JBL. Maybe another JBL would suffice.

The turbocharger is all but a gimmick.

What it does is plug into the ports, then comes back around in a U shape and go on top of the sub.

This increases available port space and lowers tuning frequency without lowering output. They claim a 12 hz bottom limit for their latest VTF-3 HO sub they are working on with the turbocharger.. which is pretty damned impressive. Search around about it on HSU's site.

I can't believe it. It's the 1980s again. Next decade it will be the 60s again. Last decade it was the 70s. We're stuck. Someone stop the nostalgia! Please!

Seriously. Turbo?

Turbo cars are very much alive today just not in the 80's. Some of the fastest cars in the world are turbo powered.

I'm not talking about real turbochargers. I've got one, love it, thanks. Although many of the top performing ones these days are going naturally aspirated.

What I'm talking about is the reemerging use of the word "turbo" to designate a high performance item. My vacuum cleaner has a "turbo" attachment. Which might actually loosely fit the description. However, a 12" section of single curved tube does not.

Your welcome. I knew you didn't mean a real turbo. All Hsu is trying to do by using the word turbo is imply an increase in performance. Even razor companies do it "mach 3 turbo". I guess I should discuss this in a seperate thread though because I'm high jacking the original poster's question.

I had two JBL subs(PSWD112) that were the predecessor to the PB12. While JBL makes good subs the SVS 25-31(since you want a tube) will blow it away.

I've had the Hsu VTF-3 MK II for a week and am thrilled with it. In a fairly difficult room (25x12x9) opening into 2 other rooms it sounds absolutely great. Music in stereo mode is awesome and the movies blow us away. I'm in St. Paul - if you ever get down this way and want an audition PM me and I'd be happy to help you out.

I think another reason why Dr. Hsu nicknamed the accessory "turbo" is because he likes cars.

Ahhh, but when it comes to audio you just have to break the law every now and then

Yeah.....I break those laws every now and then myself

My favorite times are when the Grandkids are getting rowdy and the Wife is away and I get the chance(not often enough)to crank the system sufficiently to......Drive the Kids Right out of the House!!

When they see me move my listening chair to the sweet spot....they instantly make other plans

Thanks for the invite. I'll keep it tucked away in my memory bank.

The main problem with this turbo sub is that it will have very little power at all until the rpm's have built up, by then the average Axiom powered box will be vanishing over the horizon.
