So we finally found ourselves in a position (wife and I) to upgrade our home theater sound system to better match our 65" Panny Plasma.

The problem I'm facing is I finally picked out the perfect receiver to go with the Aperion Audio Verus Forte surround speakers and SVS PB12-NSD sub, and it probably won't work in the space I have.

If I were to get the Onkyo TX-NR818, I would only have about 1/4" free space on top of the receiver, 1" on each side, and completely open front and back. That 1/4" is probably no where near enough for proper ventilation even with the open front and back. Please tell me I can get away with it if at all possible. If not the backup receiver I picked is the Denon 3313CI which is shorter, but that doesn't have the Audyssey XT32 feature I so desire.

I have the option of drilling ventilation holes in the wooden shelf above the unit but the cable box sits on that shelf and doesn't sit very high off the shelf itself.

Is the XT32 really worth me pulling my hair out over this? Getting a new unit isn't really feasible as I had this one custom made and I really really want to keep it.

Any advice you guys can give would be appreciated. LOVE this site and have been researching things here for quite a few years. I believe this is my first post.

Even with a couple fans in a push pull configuration, I would be wary of there being only 1/4" of clearance, maybe someone else with more experience can chime in.

A picture would help by the way.

Could you not rearange your cabinet to put your receiver on the top shelf? Or do you not have any clearance there either? You need more clearance than that regaurdless of which avr you buy.

You could get a Pioneer avr with the D3 amp that runs cool with plenty of power. I would still look into better ventilation.

Unfortunately that's the only space I have to work with. I'll definitely look into the pioneer as well. Most of the other receivers I've considered are only 6.5" which should work. The onkyo is almost 8" tall.

Denon AVR-4311. Audyssey XT-32 and only 6.7" tall. That should work nicely. I am replacing the Denon AVR-591 that came with the Boston Acoustic speakers that is the same size. No ventilation issues now at all with the open front and back. It's close to the floor of the sub level so it's always cool there as it is. I know the new receiver is more powerful but it shouldn't be an issue. Nice to have the 9.2 to give us the option of running another zone when we finally leave NY and get a bigger place.

Thoughts?

I'd look for a new cabinet (or place the AVR on it's own stand outside of the cabinet) as you really should have at least 3-4" clearance to ensure there are no ventilation problems down the road (which is more often the case with folks who just try to stuff the AVR into a hole and forget about it).

Pioneer recommends : 40cm = 15.748" eek.gif - 10cm = 3.93701" & 20cm = 7.87402" for the VSX-1122 YMMV rolleyes.gif


Just my 2¢ - take it or leave it for others

I had considered a new cabinet but every one I have seen all have the same problem. The space between the shelves give no where near the recommended space above the receiver.

I assume the middle shelf is not adjustable or you would just move it up, right?

Swap the receiver and cable box. The speaker can remain on the cable box (just point it upward), or it can be placed on the same shelf as the left/right front speakers.
