I'm working with an extremely limited budget of <$1000 for treatments.
I attempted to calculate the first reflection points, and I'll follow this up with the mirror-technique, but I came up with a couple questions based on the drawing below:
The couches are micro-fiber material, over-stuffed style, FYI. The sub (not shown) is on the left side wall, 5" from the wall.
The calculated reflection points on the left side of the listener pass through into the adjoining room. Due to budget constraints, I'm wondering if I can "get away with" ignoring this wall (for now), or if some level of treatment here would still be recommended? Got thoughts?
The couch on the right side of the listener is only about 2 inches lower than tweeter level. The calculated reflection points are, therefore, just a few inches above the couch back. Mounting panels here would put the calculated reflection point at the bottom of the panel. Are there any special considerations for this? Moving the couch is not a wife-approved option.
How much higher than tweeter-level should panels extend? Perhaps 2'x2' traps behind the couch would be enough?
I see the tri-corner, super-chunk style of bass trap is very popular - however it's expensive. I can't find the quote now, but I thought there was "minimal" gain when using a full corner trap over a panel positioned across the corner. Using GIK pricing, 4 tri-corner traps, for example, amount to appx $520 (without shipping) whereas 4 bass trap panels would cost only $280. In a tight budget application like mine, what is the biggest bang for the buck here? Should I really "splurge" for those tri-traps (or a similar DIY option)? Can I "get away with" the bass panels straddling the corner?
As usual, any and all comments or suggestions are welcomed.
Rough rendering of potential placement:
(GIK Panels used for example: Total Cost $550 - shipped)
Right-side: 3-gik-242-wall-panels 24x48x3.5"
Front Corners: 4-gik-244-bass-traps: 24x48x5.5 - stacked 2 per corner
Back-Wall: N/A (open to bar/kitchen area)
Floor: Area rug
For an additional $50/panel, I could add "scatter plates".
Pending REW analysis and in-home recommendations from installers, does this seem to be a realistic first-step for acoustic treatment of this space?
