Speaker Placement Conundrum

So I laid out my columns in my theater last night. I did use the Erskine Group layout service. I already had my riser built, probably should have done the service first but it is what it is at this point. Due to my door location (not ideal but it made sense for the kitchenette on the other side) my riser is a bit different. In order to use columns I have to move the columns about 6-10 inches different than what the layout calls for. If I just get some angled speakers and mount them to the walls I can place them exactly where the plans says they should be. What do you think I should do? The columns get a bit to close to my door and a step if I do it exactly as called for. I think I would like the columns but do not want to do it if it compromises the sound to much. In my head 6-10 inches really cannot matter that much for surround speakers but what are your thoughts? Wow I am rambling.

A picture might explain it better. According to the plan the left surround column should be about 6 inches further to the right and the left column should be 6" further to the left. As you can see I have a door and a step to deal with. They both are shrinking my walking space.

one option is to reduce the depth of the column make them decorative rather than functional. You way even want the speakers to protrude from the front. You can straddle a step with a column

Do you have any examples of that? I was thinking maybe a multidepth column but that could look a bit strange. I supposed I could make the frame holding around the speaker a bit deeper so the maybe 2" of the speaker is outside of the column which is hidden by frame and GOM.

what speakers were you thinking of and what is your overall plan for the appearance of the walls?

I was thinking something like bacon race and the cinemar build. Erskine group had triads in the plan but I am planning on going with JTR Single 8-LP if in a column or Single 8 slanted style if not.

just did those speakers in the smallest column I could build. From memory the sides of the column were cut at 8 inches wide. The wall treatments were two inches leaving 6 inches protruding into the room.

Now wide will the walkway be if you position it adjacent to the steps?

Do you have the dimensions of those columns? I was making an assumption of a 17" wide column if building with 3/4" mdf. I was also assuming they need to be 8" deep. That would leave 22" of stair space, which is usable but it is tight. Do you just pin nail the speaker grill to the column? Or is it attached in away that it can be removed.

From memory the sides were cut at 8 inches, I don't remember the width. The fabric grills are all friction fit (tight) and designed such that the fabric passes 1/4 inch or so over the fronts of the speakers. I used cherry veneer plywood with iron on edges, The stain selected by the client was super DARK. Almost a waste of the cherry. Could have just used birch ply. But really easy to get an even look

Any closeups or design tips to make the fabric grills friction fit? I was planning on just pin nailing them but removable would be a much better option. Do you typically use a veneer for the columns or was that just part of the design/look.

I will grab some pictures, the cheery was in anticipation of staining it a color to match an inspirational photo the client provided but after preparing 6 sample stains on scraps the dark was selected.

Nice work as usual Jeff. I guess I do not see the friction fit, are the grills friction fit from the two sides of the column? Do you typically build friction fit columns or do you typically do something different.

Every project is different. In this case the fabric frame which is a rectangle with inside another rectangle. By controlling the size of each you make it a snug friction fit.

if you make it too loose just add a little Velcro.

Exactly! I would consider employing Big for assistance in this arena. Yes, It will compromise sound if they are placed differently. They were placed there for a reason. At a minimum, you can make the columns 4 inches in depth, but that leaves no room for error as the speakers are just under that depth...by about 1/16th of an inch. Remember, it will also compromise your HVAC vents in the floor.
