I know this isn't RL related, but figured this is the best place to ask. I recently installed a set of 8" coaxial ceiling speakers in our main living area as well a pair of two-way exterior speaker on our back deck. Both pairs are driven by a centralized stereo receiver with Bluetooth and A/B speakers that I wired in our hall closet. The frequency range on the ceiling speakers is 55hz to 20k and the outdoor ones are 65hz-20k. So far, we're loving the setup, but I'm a little disappointed with the bass output at lower to mid volume levels. The receiver I have is very basic and only has a "bass" and "treble" setting that goes from -10db to +10db. I'm not certain where the cutoff points are for these settings and it doesn't seem to help all that much with the bass output. The receiver is 100 watts per channel. It and the speakers will play very loudly without any distortion, so I know power isn't the issue. It just seems to be a matter of where the "boost" is applied with the bass and treble settings. I was thinking a 7- or 9-band equalizer in-line such as the Behringer FBQ800 would help this issue. I've never had any experience with them and really don't want to spend an arm and a leg for it. Can any of you esteemed audio gurus provide some advice as to whether it would help or if it's a waste of time and money?
