Poor bass and treble.


I’ve owned a 5.1 set of Klipsch Synergy 2 (sf-2 floor standers, and a ksw-12 subwoofer) for about 10 years. I’ve always been very pleased how they sound, until I upgraded my receiver (Yamaha to-v377. Now the bass is either way too strong or way too weak. Often it’s not there when you want it (gun shots and explosions) and overbearing when you don’t want it (dialogue, and ambiance). I’ve been fiddling with settings for a long time, but can’t seem to make more than minor improvements. Any tweaking I can do or is the receiver I have just known to have anemic bass response?

I dont remember the model, but it was a yamaha as well, the v377 is nearly identical with HDMI 1.4 ports.  the v377 is two years old at this point. was brand new to me though.  I dont use the subwoofer passthrough, i use the subwoof out from the receiver. 

At the subwoofer, turn your subwoofer volume to zero. Set the crossover at 80hz. Make sure your phase is at 0 degrees. Same at the Yamaha setup which you should see in the setup/speakers section. Make sure you have the speaker 'ohm set correctly.

Start some music or something you are familiar with and gradually increase the subwoofer volume at the subwoofer until you like it. If it sounds "not in accord with the speakers", turn the phase on the subwoofer to 180 degrees. Repeat the listening exercise.

Sorry I haven’t replied in a few days. I’ve been trying hat process periodically for a couple years. I don’t see any option to adjust ohms in the setup. How do I ultimately rule out this being a poor receiver? It seems improbable that it would take this much tinkering to make this >$2000 set of speakers sound better than my $50 headphones, or the stock speakers in my car.

but on the other hand, I’d hate to waste money on a new receiver and still have lack-luster results. 

Yamaha receivers can usually be configured for 8 ohm or 6 ohm speakers (6 ohm setting usually works for 4 ohm speakers as well).  The Klipsch are spec as 8 ohm, but you never know how low the impedance can drop.

I would suggest downloading and reading the manual for your receiver.

The speaker impedance can be changed using the Advanced Setup menu.  Read page 64 on the manual.  There is a special way to access the Advanced Setup menu.
