Hello. Brand new to the forum. Yesterday I replaced my old hk htib with a brand new Yamaha 7810 and a set of used psb speakers . Image t55 tower fronts. Alpha b1 surrounds and a matching large center channel. (Can't remember the model at work). Currently using the hk 200 watt 10 inch sub from the htib. I did the setup and the ypao equalization and everything sounds very clear and dialogue is (finally) discernible at low volume. Just missing the punch. I may have overestimated the strength of my speaker setup but I was expecting more low end. I have the front and center speakers set to large and I have the towers biamped. I realize that a decent sub would be the best way to get better low end but I also thought that the towers would do a little. They are rated to 36 hz. Sounds like doors slamming, gun shots, and even the male voice are all a little underwhelming. I tried manually eq'ing it but that made everything muddy. My question is, is this setup capable of decent, crisp mid bass in a small/medium 14x13 room? I only started setting it up last night and haven't even tried music yet. I am not experienced with av but I am a musician and can hear when things are out of balance. Is there anything simple I may be overlooking? I was expecting to be a little more blown away based on the reviews of all the equipment I'm using. Also my current receiver is 110W perchannel (plus fronts biamped) compared to the hk's 30W per channel not biamped and it doesn't sound much bigger. Ty for reading/tips.
