Need 7.1/9.1 speaker placement advice

I live in a fairly tiny apartment in Japan.
I currently have the following setup


Front L/R Sierra Towers
Center Sierra horizon
Rear R/L CMT-340
L/R Surround CMT-170
SVS Subwoofer.
Receiver onkyo T-RZ810


I just ordered a new Sierra Luna pair from Ascend. My question is would it be worth it to move the 170's to front high surrounds and use the Luna's as the rear surrounds....or just swap the 170's for the Luna's. Also curious to know whether you'd keep the rear surrounds positioned as they are now or lower them....or even put them on the back wall? Thoughts? I know its a small room, but here in Japan we don't have much space. LOL.

I'd look at keeping the speaker count on the low side in that small, reflective, room. Luna for the surrounds would be my choice, just to keep the base level consistent in tweeter-type. I might also take the opportunity to lower the surrounds 6", or perhaps more, but do some testing before deciding on the final position.

You might also consider some additional toe-in on the front speakers, to improve the coverage area, given that your seating is more to the sides of the sound field.

Instead of investing in more speakers, I think your best option going forward would be to invest in some room tuning devices. Some absorption on that front wall, for instance would probably result in a much cleaner sound. Contact GIK Acoustics (or similar company) and let them design a set-up for you to best take advantage of your speaker investment. Design services are free.

Swapped the Left front and the sub-woofer to get it out of the corner and made a sharper angle with the 2 front speakers. Was this what you were referring to by toe-in. Still waiting on delivery of the Luna's and the new speaker mounts. With the new mounts I'll also be able to adjust the downward angle of the speaker more. I was also thinking to lower the surrounds and increase the downward angle towards the rear seats if possible.


Thanks for the advice on the tuning devices. I'll look into that.

Is your right speaker closer to the TV and the left speaker? The should be symmetrically placed on both sides of your TV. Also, is your centre speaker next to the right speaker? The centre speaker should be exactly between the L/R speakers.

I think I would also keep this system to 5.1.

Yes I have to have the right speaker where it is and the rear right speaker where they are because they are constrained by the size of the couch and I can't really move the couch anywhere else in the room.

Given that knowledge, should I move the sub back to the corner like the original photo I uploaded where the speakers were closer and more symmetrical to each other?





I suppose I could HTPC and the receiver in the cabinet below, but then the HTPC especially gets too hot without proper ventilation, even though it has a cooling system in it...


That way I could center the center speaker better...

Yes, switch the sub and left speaker so that your L/R speakers are symmetrically placed relative to the display. Slide the HTPC over so that you can place the centre speaker exactly between the L/R speakers.

OK, did that. The center channel Tweeter is considerably below the Tweeter on the front left and front right speakers. Any ideas how I can elevate the center speaker aesthetically in the current configuration?

Also is the angle of the front left and front right speakers OK? Should it be sharper, wider, or good just the way they are?

Might be easier to lower the tv? Looks a little high anyway, but it could be the angle. Also, experiment with toe in. There’s not really a one size fits all.
Oh duh! You were wondering about the tweeter height. I would try and point the speaker up towards your head. Otherwise a shelf might do it.

How about the new Luna’s for the rear surrounds? Agree that we need to lower those? Point them further downward toward the listening position?

Maybe put your HTPC below it for some lift. Or some boxes. Try to get the centre speaker just below the display. Even angle it up if you can.

You tell me. You're the one listening to it, I'm not. Do the L/R speakers sound better pointed at you or pointed straight into the room? You'll hear the difference. But which do you prefer?

Maybe these, to raise the center speaker to tweeter height? How much room do you have between the top of the center and the bottom of the TV?

Improved center speaker height. Maybe get some doorstops and give it an upward tilt?
