People complain about lack of bass, not enough mid range. Solution?

@knotscott

Interesting schematic above. Seems a bit convoluted though. It’s from A receiver with a built-in amplifier and I’m hard-pressed to see where there’s any quality to do much of anything. It does seem a bit strange though the the way they have the speaker split between main and surround signals. Why would anyone wanna do this? Maybe the internal settings allow for by biamping and changes the nature of the signal path? who knows

That might be a bad example, as there may be other selection requirements not shown... I’m sure there are others.

It doesn’t provide the advantages of a true 2nd amplifier, but running a separate output channel for each driver, does offer the tweeter an output that doesn’t have the responsibility of driving the woofer.

Glad the changes made your system more enjoyable. Always try speaker placement first cuz it's free! A lack of bass usually means a lack of power/drive. This can be the speaker or the amp. If you're happy now you just needed more power or an amp that could better drive your woofers. In my experience many systems are compromised by the amplifier's lack of control of the woofer. Too much bass was actually loose/slow bass that muddied the lower mids which makes the entire midrange less transparent and clear. The bass deficit was simply not getting all the woofer had to offer. Once resolved speaker placement can get you most of the way to a balance that pleases. Treat the room only when all else fails.

@panzerwagon, a good post. I agree.

@noir59, "Treat the room only when all else fails" The room itself creates huge problems which happens in all rooms, an unavoidable fact and is the downfall of many potentially great systems.

If you have something handy like a bluetooth portable speaker for example a JBL Flip 3 or 4 or ? carry it into your tiled bathroom and listen then carry it outside and listen. The different sound is caused by room acoustics. Also place it on a table near the middle of your listening room, then try it in a corner on the floor and you will hear lots more bass. It’s not good bass it’s just more but boomy.

This simple experiment will help you understand how acoustics play such an important role.

Room treatment is paramount! Ignore at your peril 😲

I finally got my best bass response. Running full range speaker t s and 4 subs
