@gdnrbob you apparently missed my post just above the GPT post. I said basically the same thing as you. HOWEVER, I thought it interesting the reply from GPT.
Has anyone here set up a system with tiered subwoofers handling different bass spectrums?
Has anyone here set up a system with tiered subwoofers handling different bass spectrums? I currently have bookshelf speakers fully crossed over to a pair of smallish symmetrically placed, force-canceling stereo subwoofers at 160Hz, and I am thinking about adding a big, ported sub and fully crossing that over to the stereo ones at 60Hz. My setup will easily allow me to do it (I have a miniDSP Flex that is applying DIRAC Live room correction to my current 2.2 setup downstream and that preamp is handling the full bass management duties right now, so the miniDSP only sees a pure 2.0 system at the moment--I can just attach the new sub to the second pair of outputs and use the miniDSP to handle this level of the bass management). Am wondering if anyone else has tried this? I am looking to improve bottom end impact and extension with the big ported woofer (looking at SVS PC-2000 Pro) since the stereo ones are not currently reaching down as low as my previous sub (currently a pair of SVS 3000 Micros; before these, I had a single SVS SB-3000).

@fatdaddy2 @gdnrbob please don’t confuse me (the OP) with gdaddy1; I never said anything about AI. It has nothing to do with the main topic of discussion. -Ed |

I agree! You cannot improve the very low bass of speakers, if they do not have good low midrange reproduction see here. I agree with the others above, subwoofer crossover 100 Hz or lower to keep directional characteristics intact, true subwoofers are designed to fill in the last octave of 20-30 Hz.😎 Mike |
Several thoughts — as others mentioned your crossover is set way too high. Your speakers I believe go down to 79Hz (-3dB) so I’d try setting it maybe around 80Hz - 90Hz and see what that does. Also, I’d be hesitant to mix a ported sub with sealed as it can introduce integration issues with group delay, etc. Last, for only $50 more you can get a pair of SB1000 Pro subs that go down to 20Hz (-3dB) and have a smaller footprint/presence than the PC2000 Pro. But a huge benefit of doing this is that you’d now have a Swarm array (4 subs), which many experts recommend as one of the best subwoofer setups possible for optimal bass a mitigating room issues. That’s absolutely what I’d do. Hey, it’s SVS so if it doesn’t work out just send’em back so no harm no foul. Just my $0.02 FWIW, and best of luck. |
