Anyway, my current AVR has two LFE outs, but they're not independent. Basically one LFE out with two connections.
1. Would I benefit most from upgrading to an AVR that has two independent LFE outs (eg. Denon 4500), or should I just get a miniDSP 2x4 HD for the subs?
2. Until I upgrade to a miniDSP and/or a better AVR, should I level match as best I can and then recalibrate with AccuEQ using just the Monolith 15 connected, or have both connected and recalibrate?
3. My room is about 1800 cubic feet, two rows with five seats. Is it overkill to keep the SVS with the Monolith?
I will answer your questions in reverse order. First, all kidding aside, I don't think it is overkill to have both subs in your system. But, they might cancel each other, from about 20Hz down, or even starting a little higher in frequency than that. They have different tuning points, different amounts of DSP applied to them, and different inherent frequency responses.
Until you have better EQ capabilities, I would start with just the Monolith, uncalibrated, and then add in the PC2000 once you have a good listening or measurement baseline established. (I would probably not use the extended mode on the Monolith, if I wanted to experiment with pairing it with the PC2000.)
Did the bass get better, worse, or no change? Depending on the answer to that question, you can then explore your calibration options with AccuEQ. Just the Monolith, or both connected? You really won't know the answer to those questions until you experiment.
Long-term, I think that a miniDSP will work much better, especially for two completely different ported subs, than any form of automated room EQ including Audyssey XT-32. But, to use the miniDSP effectively, you also have to have a laptop, a calibrated UMIK-1, and REW. (REW is a free download, but there is a learning curve.)
As a general rule, integrating two identical ported subs, in a room, is a much easier task, although it is not always dead simple even so. Placement is still important, and adjusting the phase control on one sub may be necessary. But, if you really want to try to integrate two dissimilar
subs, then REW and a miniDSP would definitely give you the best chance to do it effectively. I hope this helps!
PS: In case you are thinking of this question, as you read what I wrote, I would definitely also consider selling the PC2000 and buying another Monolith 15. That would especially be the case if you don't have a laptop, or don't want to invest time and effort in REW. In that case, you might be able to get by with just the Denon you mentioned, although REW and a miniDSP would still have advantages. (Or even just REW would help, for that matter.)
