Has anyone here set up a system with tiered subwoofers handling different bass spectrums?

Boy I'm sure glad we're getting AI input from the likes of Ch*tGpt instead of input from forum members.  Pretty soon we'll be able to generate thread topics, and all inputs from AI, and the actual forum members can just retire and listen to music.

@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.

Bottom line... if you want great bass and dynamics these aren't the right speakers. The subs are fine. No need to buy another one.

These speakers are great for near field, low level listening for classical music. But if your looking for some punchy Jazz tunes or electronic chill music the little drivers in these things can't handle it. 

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.😎

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. 

Okay, so it seems a few people are missing some aspects of my setup here...

Firstly, the 3000 Micros are fully crossed over at 160Hz; slope is 30dB/Oct for high- and low-pass filters, and completely time aligned via REW scan/manual delay set for the speakers. This isn’t some half-assed setup where my subs and speakers are overlapping for multiple octaves. Do it right, or don’t do it at all.

Secondly the 3000 Micros are a pair that is symmetrically placed extremely near to each sub’s matching speaker, so localization is a complete non-issue and in fact imaging is significantly superior to a single sub placed anywhere. I wish I could figure out how to post images in this forum so that you can see. I actually have a paid of IsoAcoustics ISO-155 stands arriving today to really get them even better aligned with each other. Their acoustic centers are exceptionally close to avoid problems like comb filtering and poor integration--essentially, the design is meant to mimic something like Blade 2 Metas or R5 Metas (granted, I am sticking with at 160Hz crossover since that is where my room's Schroeder frequency is, instead of crossing higher which would better simulate the aforementioned 3-way speakers).

Finally, I am acquiring the PC-2000 Pro open box at substantial discount. This one will be fully crossed over to the 3000 Micros with a 36dB/Oct slope. I am trying to decide if I want to do that at 50Hz, 55Hz, or 60Hz. I debated this model against other models for quite a while and am looking to keep to a single unit. The down-firing driver of the PC-2000 Pro combined with rear-firing port will be even better protection against potential localization compared to front-firing drivers and ports, and of course this sub will provide significantly greater extension and slam than the pair of 3000 Micros do. Relieving those little woofers of this deep bass/extreme excursion frequency range will also further improve their performance up to their upper band.
