I'm looking to get the best subwoofer in terms of below 20Hz extension I can for about $1200. Amongst commercial options it seems the PSA XS30 is probably the best for my goal. I'm in a rather small closed off room so I'll be getting plenty of room gain.

I had initially written off DIY since it seemed intimidating, but I saw the DIYsoundgroup.com flat pack stuff and I thought it wouldn't be too bad for me to build one.

So basically, within my price range of $1200, what gets me better below 20hz extension: PSA XS30, or an easy DIY build like flat packs?

Right now I'm looking at building 2x 4 cu ft flat packs with a Stereo Integrity 18" in each, all run by a single amp. I can run two subs off a single amp, right? I heard the iNuke 3000DSP was good, not really well versed in this area though.

that combo would actually be quite good.

it would give you about 2000 real watts or so (assuming that you get the right impedance/vc option). you'd want to end up with 4 ohms and run the amp in bridged mode. dual 4 ohms coils gives 8 per driver. two drivers in parallel give 4 ohms.


the dsp would give you ability to eq if you need it.

the si woofers are turning out the be quite good and probably the best bang for the buck at the moment.

my rough guess is that you could be looking at about 6db more with the si/behringer/flat pack combo,
which is like having a second psa dual woofer sub.

Listen. It's All Good.

also, if you aren't aware of infinite baffle, you may want to check that out.

very low power to get sub 20hz content.

check out the cult of the infinitely baffled.

Not even a fair comparison, a single 15" with 725w vs dual 18's and a Inuke3000.

 

Edit: Correction, the XS30 uses dual 15" drivers tongue.gif

Behringer EP4000 is -3dB @ 5Hz. Does anyone know where the iNuke 3000DSP lands? I don't remember it being a useful option for sealed systems (capable of <20Hz).

I thought the XS30 was dual 15's?

Still not fair due to wattage though.

I used to own dual Submersives and now own 8 SI DIY subs.

I've compared dual SI 18's to a single Submersive and the they were almost identical both in sound quality and in output. The dual SI's had slightly more output though, so you can imagine how they would compare to the PSA sub. No brainer here IMO.

You're right, it is dual 15's.
