Multi Ch. speaker placement tips needed



Hello all,

I’m initially setting up a 5.1 system in a < 14ft x < 21ft < 8.4 room. Closed off 100%, save for AC ducts. The ceiling gently slopes up to 8.4 then back down, to about 7.9 ft.

All the speakers are Silverline Audio… Sonata IIs; Center stage; SR 15; Velodyne DD 15. If I add to this config it will be a pair of Minuets for the middle surrounds and another sub for the rears… that has yet to be decided though.

Center surrounds will need to be set onto the side walls if done at all.

Center and mains are set to the < 14ft wall.
Where is the center to sit? On the same plane as the Mains? Or behind them? How high off the floor?

The rears are on Sound Anchor stands and the tweeters are right at ear height, 48 – 80 in.

If I go ahead and add the senter surrounds should they also be set as the rears in height?

Higher? Making for a hemispherical config?

Lower? Making for an increasing slope up to the rears?

Thanks much for your experiences & interest.

Thanks

Snell! That was the name! I had forgotten all about them. But these are pretty pricey, aren't they?

Nope.. hadn't seen that item yet. Thanks.

OK ... who makes affordable bi/di poles THAT PLAY WELL WITH other speakers?

AND CAN BE MOUNTED ONTO A WALL OR A STAND?

Soooo.... For HT all the talk of dipole - bipole is just that. Talk. No supporters huh?
with no wife, kids, cat or dog, the main seating position well be a touch short of center room, closer to the front speakers.

I haven't made the exact measurements yet from the LP-VP to the front mains which will be set off the screen wall to around 48" (to the drivers)... and 24 - 27 inch off the side walls, making them about 7.5 ft. apart.

The center speaker hasn't been placed at all... but I'm guessing it will be just under the screen adn slightly in front of it, at 20 - 23 inch high stand, and no more than a foot forward of the screen, with some slight up angle.

The rears are back ported, so they'll wind up no more than two feet off the rear wall, and between 12 & 18" off the side walls.

The MAIN bit here is that 2 ch is also in the mix. Heavily.
In fact it is the predominate choice, the HT aspect is a distant second, yet remains important.

Zat help?
Thanks Bob

I think I ran across that SVS testing description... it was on the "NSD" model. Very impressive. I'm maybe gonna change my mind from HSU to SVS based on that.

The funniest thing I saw also was a reviewer who said almost identical things about BOTH HSU & SVS models. "Best I've ever heard bar none!". that's as maybe, however, it sure struck me as odd with both makers posting his review of their respective products on their own websites.

Oil well.
The setup is set… short wall. The screen is hung, the PJ is set too. The room is finally shut off effectively during listening/viewing .sessions. The lighting is hung and done. The sound scheme is currently 5.1, though 7.1 might be the end result if I can figure out just where to place the side spkrs.

Now I’m considering dipole/bipoles for the surrounds and directional for the rears. There will be scant little latitude for movement of the rears or center surrounds. Greater flexibility is had with the center ch, mains, and sub.

The listening position is likely to be determined by the 2 ch performance + the visual image viability, and in that order. I’m figuring to do one pair of speakers at a time, mains … rears… then perhaps sides at some later date… then the center and lastly the sub.

Acoustic treatments will follow all the above…. Consisting of corner bass traps, first reflections and possibly some diffusers.

Where it’ll all wind up and how much acoustical treatments are used is anyone’s guess right now.

the biggest variable for me right now is deciding on the use of either dipoles or bipoles as either middle surrounds or rear surrounds.
