Open Floor Plan [message #64428]

Illuminati (1st Degree)

Anyone here tried to set up a decent 7.1 system in an open floor plan? Our kitchen and living room are just one big area. The two side speakers are sitting on the floor on either side of the couch and the rear speakers are installed in the wall on the other side of the kitchen, almost twice as far from the couch as the front speakers. It's hardly an ideal setup but the couch can't be moved any further back.

Any recommendations? TIA.

Generally, open spaces are easier to work with than small rooms, at least where acoustics are concerned. I'd probably put the main speakers on stands flanking the TV, left and right and at about the same height or maybe just a smidge below. Then put the surrounds beside you and maybe a little bit behind you and slightly above ear level.

The mains are flanking the TV and the L side/R side speakers are flanking the couch. It's the rear L & R I'm concerned about since they are so far back. I guess if I want to move them forward, I'd have to drop them down from the vaulted ceiling but then I run into major aesthetic issues.

I always suggest that the tweeter of every speaker should be at ear level. Wayne, correct me if I'm wrong, but is that not the way speakers are designed, that the Tweeter is the "eye" of the speaker, so to speak. Ever since reading about that and trying for myself my eyes always look at the tweeter as the centre of the speaker.

In general, that's probably true but there is a forward lobe that may or may not be cenetered on the tweeter. In the best speakers I've seen, it is actually in line with the center of the speaker or even the midwoofer. The real trick is whether or not it is angled up or down, which would place the best listening spot at a different height depending on distance. Here again, the best speakers are uniform over a fairly wide arc, perhaps 90° in the horizontal and 30° to 40° in the vertical (+/-45° in the horizontal and +/-15° to +/-20° in the vertical).

The rear speakers are angled down, but they are so far away (15 ft horizontal) that even with the receiver signal cranked, you can barely hear them. I think I need new speakers with higher power in addition to changing placement.
