Any thoughts/opinions on my First (of 6) DIY Acoustic Panels ??

I have 4 hours into this one, others should take 2 hours a piece. I used Jon Risch's DIY as the basis for them, so they are built to be effective.

It is 24"w x 48"h ..... 3 inches think and spaced 2" off the wall ....

Now, for asthetics :) See attached Pictures ....

This is 2" off the wall, all the way around. Not sure why the picture looks like it is angled in at the bottom. Strange.

I think they look Great and I like the extra wood quarter round on the outside(if thats what it is).
Nice job!

I now have the second one built and It was a much better experience. :) 2 hours total to build the second one.

Now I have a few other corner bass traps to do.

I have to say, I notice improvement already with 3 corner bass traps, and 2 wall panels. I'm looking forward to getting the rest done tonight.

Yes, I have 2 extra 1x3's on either side, covered in fabric ... for looks only.

Great looking panels - wow. i'm about to treat a room DIY style, hope i can get some nice looking results too.

i have a question about optimizing high frequency panels to absorb some mids and maybe low mids as well. here's my plan, and i'd like to know if my logic is right;

using 2 inch OFI-48 (oc-703 substitute) for the wall panels, i am going to make 4 inch deep panels in order to leave 2 inches of air behind the rigid fiberglass.
i'm hoping this will absorb some lower frequencies that the ofi-48 will absorb unaided.

Thanks for any input!

You're essentially creating a broad-band absorber with that design, which by definition should do a pretty credible job on both ends of the spectrum. You can actually get pretty low if you design the panel right and use the right materials.

Very classy look on the side panels. That's a lot of time to put into them but the results are very nice.

Very nice htCanada.
I too made my own some months back, very cheap to make and easy (despite being DIY inept!). Used wadding on an MDF based, and industrial strength velcro to attach to the wall. And they work a treat in the room, both sonically and cosmetically!

Those look very nice !!!

FYI to everyone, I purchased all my speaker grille cloth on sale 50% off (12 meters of it). I have built 4 of these panels now, all identical.

Total Cost - $26.00 each ! :)

Exactly what i was hoping for - excellent, and thank you kindly for your reply.

materials; OFI-48, batting and burlap to cover, lightweight wood for the case (maybe heavy wood would have been better come to think of it), screws and staples.
