I did look for an existing thread on this, as I thought it would be a more common issue, but didn't see anything specific.
I am a fan of Yamaha receivers and now have 3 in operation. My theater is a 5.1 and sounds great. My garage has a more basic 2.0 A/B setup for inside and outside of the garage. I just acquired an older 7.2 Yamaha RX-V665 receiver. It's a few years old, but otherwise it's a great receiver in perfect condition. Now in use in the home office. ...I know, just bear with me.
BACKGROUND: I picked up some new Polk T15 bookshelf speakers because they were half off at Best Buy and I couldn't pass them up. I do like Polk (I know not all of you do), and they're perfect for their intended application in my home office (about 10'x12'). I was previously using a pair of active bookshelf speakers (Edifier R1280T). They were great, but I was looking for something with fuller sound, and a little more power when I wanted to crank it. They also had 4" drivers, and the Polk has 5.25" drivers and spec'd out to reach a bit lower than the Edifier speakers. 75Hz low for the Edifiers vs. 45Hz for the Polks. This was important as I'm not using a sub in the office, nor do I want to add one for space reasons.
MY ISSUE/QUESTION: I connected the new Polks to the above mentioned Yamaha RX-V665 7.2 receiver. I connected them to the FR (front right) and FL outputs on the receiver. I turned it on and everything worked great, except for the sound. There was zero bass. I realize this is a theater receiver, but it should have no problem running a 2.0 setup. I saw that the sub icon was lit up on the display, so I was thinking that the receiver thought a sub was present. I went into the setup and changed sub to none. Sub icon went away, but the sound was exactly the same. I used the YPAO calibration mic (which I didn't think would be necessary since I was just using it for 2.0). Overall sound improved (props to YPAO), but still no lows. I was thinking I had the polarity reversed on the speakers or receiver. Nope. Played with crossover settings on the receiver to no avail (which shouldn't have made a difference anyway because there is no sub connected). Finally, I took the speakers to my 2.0 stereo receiver in the garage and connected them and they sounded great. I found the nice lows I was looking for. Because I acquired this receiver used, I decided to do a factory reset. Still no lows. I messed with the preset EQ settings. They change the sound, but didn't increase the bass. I realize there's a break-in period for new speakers, but the fact that they sounded good on my garage receiver tells me I'm either doing something wrong, or there's something wrong with the receiver. I really don't think the receiver is malfunctioning, so that means I'm probably missing something. I feel like I covered it all, but figured I'd ask you experts.
One thing I haven't tried yet, which I was thinking about giving a shot: This receiver is a bi-amp, dual zone receiver. I was thinking about connecting the speakers to the zone 2 and see if there's a difference.
Other than that, I'm at a loss. Anyone have any ideas? Should I just not be using a 7.2 theater receiver for a 2.0 setup?
