svs pb 2000 pro vs 2x sb 1000 pro

So when you add a second sub, what does the frequency response look like?

let me try i did not forgot it thank you

 

[hardcore_gamer29]

**** after 2nd subwoofer its still same

exact same

Obviously those are predicted responses, but you'll need to move the second sub around a bit to balance out the nulls and peaks in the room so wherever you're sat (within reason) the bass response is consistent.

cant do that as i dont have space for this big subwoofer. my room is only 11.70x10.70 feet

Can you use the Parametric EQ on the SVS app to raise the frequency where you have a null?

i did it already but it makes bass very bad. deepness of bass is ruined

 

[giggsy1977]

Hmm, I would have thought careful manipulation of the frequencies and gain around 80hz would have helped. Bother. Hmm, tough one to sort it seems.

80hz dip may be because of speaker crossed at 80hz

 

[giggsy1977]

You have the LFE crossover set to 120hz and the speaker crossovers at 80hz?

yes lfe default at 120hz in avr

 

[hardcore_gamer29]

80hz speaker cross is greyed out as managed by dirac bass control

 

[giggsy1977]

You could try the crossover at 90hz and but that might give away the position of the sub rather than blending in.

Adding a second sub will give you a little more volume but not more depth.

Maybe your room is more suited to a single sub?

Not sure what else to suggest, requires someone with more knowledge than myself I suspect!

the one i bought dali opticon 2 from he said i made mistake by buying ported 2000 in untreated room. he said sb 1000 pro was fine that too single. I can sell this and get 2xsb1000 pro as well. But will they give same deep oomph in movies like pb 2000 pro does? I am used to it now

 

[giggsy1977]

Two SB-1000 Pro will not give you the same 'deep oomph' as the PB-2000 Pro. The ported box has a big advantage low down due to the larger cabinet volume.

The sealed boxes may drop lower (once a ported sub receives a signal below it's port tune it drops off fairly quickly), but it's likely any signal the sealed unit receives is so low in, volume it doesn't have much impact.

Two SB-1000 Pro in your relatively small room should sound good, but they won't go as low as a ported sub. It's possible the SB-1000 Pro are fine for your use case, but only you can decide that.

Try to match this to 80Hz and see how that works.
