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?
When i got the new receiver? No. But I have tried moving it since to try and get better results. It’s currently about 12 ft from my favorite place to sit. 
So you describe the typical sub integration problem. 

What you need to do first is kill the worst offenders. What EQ options do you have? Did you use the room correction with the recommended measurements? 


Also, make sure you let the receiver do all the crossover work. If your sub has a low pass filter and adjustment, set it as high as you can. 
The sub volume and crossover knobs are at max. The Only EQ options this receiver has are for one speaker at a time (and not the sub). So it doesn’t really help boost the sub what-so-ever. I don’t think it has any room correction feature either. It does have a menu where you I put the distance from each speaker, which I have done. The is a “extra bass” option, but that doesn’t fix everything. We still don’t seem to have bass in a lot of places we’d like to hear it. Then it seems kind of one note. Like I’m Always getting a hum when I need a boom or a rumble. Rock music sounds like you’re watching MTV on standard TV speakers.

sometimes it sounds better to turn the sub off, and let my Klipsch floorstanders do all the bass, but even that, not nearly as good as it should.

Ps by EQ options I assume you mean the sliders for various frequency ranges. I do have things like “DTS: Music” but I usually keep it on “STRAIGHT”
Could you have meant RX-377?

You need to run the YPAO feature. :)
go Ahead and say it... R T F M!
ill give it a try when I get home and let you know how it goes
Didn't work. Base is still mild at best.

This kind of diagnosis is extremely hard to do, unless we are there with you listening and configuration.

Can you tell us what your previous receiver was? 

Is the Yamaha brand new?  It may need to be broken in. 

Could be a speaker/crossover configuration issue. 

It's so difficult to tell.

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. 

Have you tried the auto configuration? 



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.

After trying anything I found in the manual, I tried using the subwoofer pass-through instead of my receiver’s subwoofer output  (for the science.) The result is a VAST improvement. 
Great that you found an improvement/solution.  It could be that the bass analog circuit or DSP in the Yamaha is pretty crappy.
I took a look over some other threads. Seems to be quite a few Yamaha owners with several different models with weak sub outputs. Wonder if it effects amp pre-outs as well.
