Hey guys. I need some opinions. My current setup is:

An acoustically treated 13' x 22' with 8' ceiling dedicated basement Home Theater
Klipsch RF82 towers L/R, RC62 center, RS62's surround and RW12d sub.
Onkyo TX-SR806 130W/ch with L/R bi-amped
Behringer Feedback Destroyer Pro DSP1124P

I have run REW and have three filters correcting my room fairly well. But I never really got things as smooth as I would like them on the low frequency end. I have tried different x-over points on L/R's - 80 Hz, 50 Hz, 40 Hz, full band (both with and without double bass). Double bass set to on sends LF signal to both L/R speakers as well as to the sub. Klipsh claims a frequency response of 33-23,000 Hz (±3dB) for the RF's. I want clean, accurate, clear, tight bass as I listen to music of all genres as much as I watch movies. I am considering a sub-woofer upgrade in the next few months. My two main choices are:

Definitive Technology SuperCube I and
SVS PB-13 Ultra

Anyone have experience with both? I am leaning toward the SuperCube and using the money saved to buy the SVS AS-EQ1 sub EQ. I am tired of manually (trial & error) trying to tweak settings. It seems the FIR filters are far superior to parametric EQing and the automatic EQ selection/use are tempting.

Any suggestions, advice, opinions, recommendations welcome.

Thanks in advance,

Steve

I have the exact same setup. I'm considering the HSU VTF-15 but landed cost in Canada costs almost as much as the SVS PB12-Plus! I'm now looking into the PB12-Plus. I was assured that for a room of 3000cbft +/- the PB12-plus would handle it flawlessly. The 13 ultra is a little steep in pricing.

The link I used to have is no longer active, but there was a collection of subwoofer measurements by Tom Nousaine. He measured the Definitive Tech Technology and it's output dropped below 30Hz. Though he didn't measure the SVS PB-13, but the SVS lesser models tested had higher output, especially at 20Hz.

I think getting a SVS AS-EQ1 sub EQ is a good idea....

How big is your room and do you have any REW graphs you can post?

Life is good.

Can't find graphs right now. I will look for them when I have more time.

i had a def tech prosub1000 and a prosub 800.. both of them the quality was pretty weak compared to a svs pb12 plus2 box that i recently got...

not familiar with the higher end super cubes though.. but just from what i have seen i would take anything svs over the def tech.

also just from the specs of the prosub 1000 they say it goes below 20hz.. that pisses me off because i cant hear anything below 30hz or so from this sub with the gain turned a little over half way up..

it is like saying a car has 400 horsepower but really only has half that.. most people say the same thing.. def tech WAY overstates the capabilities of their subs.

If you want the AS-EQ1 for the automatic aspect, I understand. But I doubt it can make the sound better than BFD/REW with the right tweaks. The BFD just has so much flexibility! Can be tedius but once you have it set, it's set.

I agree 100%
REW + BFD is far more flexible, less expensive and certainly a better tweakable investment then the full on auto eq scenario.

I have ARC with my D2v and prefer to tweak my sub settings after ARC sets everything to totally flat. Totally flat for speakers is great, but I love a nice house curve for my bass to provide that punch in the chest.
