Rhoddog Posted March 14, 2016 Share Posted March 14, 2016 Bottom of the joists is 7' , room is 20 x 20 with the back wall opened up ( not there) to the rest of the loft.. A flat surface would be better than the exposed joists yeah ? Quote Link to comment Share on other sites More sharing options...
JJkizak Posted March 14, 2016 Share Posted March 14, 2016 Visually yes. Sound wise I don't know. JJK Quote Link to comment Share on other sites More sharing options...
Chris A Posted March 14, 2016 Share Posted March 14, 2016 Having diffusion on the ceiling is a good thing, i.e., leave it as-is. More diffusion is even better, as in--you can put even more angled surfaces up there if you want. You can also put absorption tiles at the "first bounce" point (halfway from the loudspeakers to the main listening position) to help with spurious reflections if it is an issue with exactly where you sit. I don't believe that you're going to have any issues, however. Conversely, putting sheet rock or plaster on that low of a ceiling is not so good in terms of the resulting acoustics for your loudspeakers/room. Higher, diffuse ceilings are better.

mustang guy Posted March 14, 2016 Share Posted March 14, 2016 Is the room exactly 20' square? There are some pretty serious room modes going on if the room is exactly square. In fact, with 7' ceilings, you would need a room that is much smaller in order to get a good bolt-area. Something like 11x17x7 would be ideal, but 13x20x7 would be reasonably good. Just don't make it 14x20x7, because 14 is exactly twice 7. 1 Quote Link to comment Share on other sites More sharing options...
Chris A Posted March 14, 2016 Share Posted March 14, 2016 I believe the OP said that the back wall is opened up to a loft. I don't see any issues with that. Enclosing the room at 20 x 20 x 7 might be an issue, as the square dimension of the floor plan, and the 1/3 dimension of the height to width/length isn't preferable.

mustang guy Posted March 14, 2016 Share Posted March 14, 2016 (edited) Chris; I read back over the OP and I'm having a hard time visualizing the room. So this is a room that is an upstairs loft that is 20' X 'something bigger' and it has exposed floor joists above? It sounds like a basement and an attic had sex and this was their child. Only kidding, everybody know basements and attics don't have sex because the ground floor always gets in the way. Rhddog, do you have any pictures you can share?

garyrc Posted March 15, 2016 Share Posted March 15, 2016 Leave the ceiling joists exposed, put in more diffusion and put absorption at the first reflection joists, as Chris suggested. The extra space of the loft might, or might not, give you some pleasant ambiance. 1 Quote Link to comment Share on other sites More sharing options...
mustang guy Posted March 15, 2016 Share Posted March 15, 2016 Now that's what I call a man cave! That's why I love pictures. I would have never imagined the room looking like that. In fact, I've never seen a room with that configuration. What was it used for before you made it your pad? I like the poochie. Too bad he is camera shy.

jason str Posted March 15, 2016 Share Posted March 15, 2016 Long span on those floor joists, blocking them every 8 feet or so will stiffen the floor above in a much needed way. 1 Quote Link to comment Share on other sites More sharing options...
Rhoddog Posted March 16, 2016 Author Share Posted March 16, 2016 I ran out of lumber so had to space the last three a little wider, the rest are 14" . Still wide ha Quote Link to comment Share on other sites More sharing options...
