Looking for some advice here from some HT enthusiasts:
I just purchased a 4645c sub to pair with a couple 4670d's used as L/R mains in a HT set-up.
The 4670's are incredible, the dynamics and midbass impact are really something to behold. With room gain, I get usable output to about 30hz.
The 4645c sub was intended to fill out the frequencies below 30hz whilst keeping up with the mains in output. I am running it off one of the 200w channels from a Anthem MCA50 power amp (same as the 4670's), but currently without eq. I am also using an Integra 80.6 pre/pro to handle the crossover, which I've set to the lowest point at 40hz.
Unfortunately, without EQ, the 4645c doesn't seem to be adding much that the 4670's aren't already handling. The bass output below 30hz using seems to be creating some port noise and interference with the bass from the 4670's. I actually prefer it turned off. I know this has a lot to do with room positioning and standing waves, but unfortunately due to its size, my options for placement are very limited.
My question is, before I go down the rabbit hole of buying more equipment to supplement the 4645c, should I be looking at a smaller subwoofer to handle the sub-30hz domain in my room where there is more flexibility for placement - or should I try to pursue using an eq to augment the FR of this behemoth? If so, what EQ would be a good fit for my current set-up? Not trying to spend a lot more $$$.
TIA
