Question Replacing JBL PB12

I'm currently using a JBL PB12 in a 5.1 system which includes Axiom m22ti, Axiom VP100 and Axiom QS8 all running off of a Denon AVR 1083. The JBL is showing signs of age and I'm not sure what to replace it with. Do I need an ampliefied sub or would passive do the job? The main reason I use a sub is to aid the m22s in the low end. In a 12x20x8 room which subs should I consider? Would the stf-1 or stf-2 fill the room? If amplified is preferable over passive how many watts are enough? Or doesn't it matter?

If you haven't done so yet fill out this form and Dr. Hsu will recommend what sub would best fit your needs.Looking at your room size I would think the Stf-1 would be a tad small.The Stf- 2 would do a pretty good job for you.I have a Vtf-2 mk1 in a room close to the size of yours and it does a really good job.

Yeah I agree with WID. The STF-1, a great sub I own one, I think would be too small for real HT sound you are looking for. It works great in my room of similar dimensions for music.
My System:

Jolida 1701A Hybrid Int. Amp with Ei 12AX7 tubes
B&W 602 Series 3 Loudspeakers
Sony ES CD Player
Sony DVD Player
Audioquest Jaguar DBS Interconnect
Audioquest Sidewinder Interconnect
Audioquest CV-6 DBS Bi-Wire Speaker Cables
Audioquest NRG-3 Powercable
Monster Cable M-Series 550 Subwoofer Interconnect
Video Cabling by Tributaries

Which sub...

Almost certainly, the Hsu guys will recommend an STF-2 or, perhaps, a VTF-2 Mk II.

But you could also consider an STF-1. It's a really good sub -- I own two of them. One for our home theater area (similarly sized to your room, but a bit smaller -- only 9' wide for most of it) and one for our master bedroom.

I think it partly comes down to your style: do you really want to rock the house or do you just need to fill in the bottom end?

And, it you decision can be influenced by available space: The STF-1 is small enough that we were able to just tuck it behind our floor standing speakers and can't even see it. Anything bigger was going to have to be an end table in our house and that wasn't going to be very popular.

Good luck.

Thumbs up

I have a STF-2 in a 17 x 18 x 8 listening room, and it does just wonderfully!

I'm sure that the "adjustability" of a VTF2-Mk2 is great, but I'm very, very happy with my recently installed STF-2.

I've never had anything close to a real home theater experience before, having migrated from a mismatched Bose AM5 Series II mains/JBL center/Altec-Lansing surrounds experience, all powered by an older harman kardon Dolby Pro-Logic receiver, so my new VT-12 speakers/STF-2 sub/Onkyo 602 receiver package is a marvelous revelation compared to what I'm used to!

The Hsu sub puts out bass that is clean and clear and wonderful, whether I'm enjoying music or movies. It adds depth and impact to everything I listen to, without ever being boomy or overbearing.

As you can tell, I can't say enough good about it!
