Is there anything I can attach to the vents that will still allow proper air flow and keep the dog hair out? I don't imagine it will be a big problem since there is no fan pulling debris in like on my PCs.

Also, what is the best way to routinely clean the AVR of dust on the inside?
Maybe something like window screen will help. Make sure it's properly ventilated with plenty of space around it for airflow.
Take the cover off once a year and blow it out with a can of compressed air.

It might be better at 90 Hz, although I doubt you will hear much difference. YPAO may set a lower crossover based on the other speakers, but I'm guessing it'll go with the weakest link in the chain (not sure, though, as all of my speakers are about the same in that regard).

The crossovers you listed are internal to the speakers. It's where the change is from tweeter to mid-range and mid-range to woofer. Don't worry about those for the purposes of setting up your system. The crossover you are setting (or that YPAO is setting) is from those speakers to your sub.
I gave up on YPAO and set the speakers and sub by ears - I have both the FL n FR set at +2.5 dB and the center at +4.0 dB - The sub set at 2.0 dB n crossover at 160Hz on AVR (crossover on sub at max and gain at 2 pm) - Watched bd Frozen movie with my kids and the sound is clear and good at the AVR volume at -30 dB and I could hear the rumbling during the movie - I still need to fine tune the system and sub location - I have some questions for the experts here:
1. should I set the sub back at 80 Hz instead of 160 Hz ?
2. will the sub get damage if I leave it at 160 Hz ?
3. is there anything wrong with the setting I have above ? What I am trying to say is: am I doing any damage to my AVR and speakers if I keep at current setting
FYI the basement is 18 x 12 with open way to the living room
Thank you

What kind of speakers and subwoofer do you have?

I got the two Infinity Primus P363 speakers and the center Infinity Primus PC351for the front - I also use a pair of Pioneer S-H453F-K for the back - Just got the Dayton sub 1200 - Thanks

The sub will not get damaged at 160 but that's not the best setting for it. I would set it back to 80.

Out of curiosity, what is it that wasn't working out with YPAO? It does more that set the levels; it also applies PEQ to try to correct for room acoustics. As to your points:

1. 160 Hz is very high for the crossover. Your speakers are capable of lower frequencies than that. Further, if I read your sub specs right, it only goes as high as 140 Hz (the highest setting it has). That means you must have a gap in the 140-160 Hz range with those settings. Personally, a crossover above 100 Hz has caused problems for me in the past. Deep parts of male voices will come through the sub and sound boomy or hummy compared to other dialog, especially if the sub is running hot. With your speakers you can set the crossover to 80 or 90 Hz.

2. The sub probably won't get damaged, but as I suggested above it might be filtering out frequencies above 140 Hz leaving a gap up to 160 Hz where your speakers pick up.

3. No damage, but I doubt you have achieved your optimal settings. Did you manually set the speaker distances in the AVR? The sub distance cannot be set with a measuring tape because the processing delay in the sub should be taken into consideration. YPAO generally sets the sub distance further than the actual physical distance to account for this.

The bottom line, though, is that you like what you hear. I'm just throwing out some suggestions.

I have a Yamaha RX-V673 that I have had just over a year.

I have a Yamaha RX-V673 that I have had for just over a year with no issues. Last night while watching a regular TV show, the power kicked off. I tried to turn it back on, and then it kicked right back off. Now when I hit the power button, the red light blinks and nothing happens.


I turned it off, unplugged and re-tried, still didn't work. I undid all of the speaker wires from the back, and tried to power it on again and still nothing.



What are my options here? I can't seem to find much online in google search, and am new to the forums.



Thanks for any and all help!!

^^^ Call Yamaha. Most likely needs repair.

How about speaker grill cloth and probably should use moisture free canned air

Rx v673

Any way that I can select 2 channel with subwoofer or do you have to use a surround mode??

I reran YPAO to get the distance then using tones to set the speakers - So far all speakers are sounding great. I also reset the crossover in the AVR at 80 Hz

Make sure all your speakers are set as SMALL, then the sub will play with two channel sources.
