BF’s Basement Studio Build Journal

The side splay walls and rear corner traps were planned as wood slats to keep the entire room from being absorptive.

That's typical with designs by John - so stick with what ever he reccomended - you can't go wrong from there. Those are broadband by their design - the varying depths make that happen. Sincerely, Rod

Thanks Rod, always appreciate the input.

A few updates. I have been slacking. Pillars placed. A layer of closed cell foam lines the bottom between the concrete and wood base, bottom lip calked to prevent leakage during curing curing process, and duct taped to prevent rise. Spacers set to allow for +/- adjustment of platform. Hardware hangs from bottom of monitor platform during curing. One week later. Positioning hangers inside soffit cavities. Frames placed for removable panel in soffit wall. Platform removed from pillars, box constructed and placed back on. Upper cavities filled with insulation and scrap. Two layers of 3/4" MDF hung for soffit walls. Mudded, primed and textured ceiling. Rear corner traps (two layers of 2" OC703). Cloud (before fabric was applied). Side splay walls. Frame for lower portion of soffit walls. Slats go up. Front wall trapping. 4" OC703 with 3 1/2" airspace behind. Rear wall. Inner 'frames' for soffits. Cover plate for access between control and machine rooms. Trim. Machine room. The rack. As the soffit walls are slightly under 4' wide I'm looking to use the White instruments 4400s for baffle step compensation rather than something of barefoot's design with a low shelf starting at 100Hz. Any thoughts on using these filters for this application?

Wow, that really looks awsome, great job! Greetings, Dirk

BF, Before Lou's jaw drops I have to say my jaw has hit the floor. Very nice work. Maybe its that time of year but there are a lot of studios coming to the finish line and its so impressive to see them all come together at the same time. Merry Xmas to all of us Very nice work. Can't wait to see the gear loaded in Peace Tom

One word... "DAMN"!!! OK, maybe 2 words... "Double Damn!!!" Man, looking great, and a huge difference between your last update and this one. Very impressive, and you've got yourself a great place to work in. Best of luck... let us know how it sounds!

Beautiful! Just beautiful. I can only hope my room comes out half as nice. I love the two-tone slats and the routing work on the front trap. Uber cool. Aces all the way! Could you post a couple close-up details on the finish work on the side slats? I want to show my contractor some pictures of how to do it right! Particularly the beveling and fastening stuff. And your soffit construction. Do you have a sketchup file of any of this stuff I can show him? Thanks, ~ Bill

Thank you for the kind comments. Initial testing for final placement of the B&W 602s does sound quite nice, although I'm sure things will change a bit as I begin to introduce gear and furniture to the room. A few subtle moves and re-cuts, but no major reconstruction was required for the soffits.

I don't know if I have any better pics than I posted (although perhaps I am misunderstanding the question). The slats were beveled so that the ends were 90 degrees from the wall in most cases (side splays are at 12 degrees) with the variation being the front ends of the slats contacting the soffit walls which were cut to meet flush on their back sides with the 30 degree soffit walls. Rather than using 1x2s beveled inside the resonators to affix the slats I beveled/ripped 2x4s at 12 degrees (to make two usable parts per 2x4) for more 'girth' as I affixed the slats with screws rather than finishing nails. I'll attach the final sketchup file. Hope that answered your questions. * Hmm, seems the attachment size limit is smaller than my sketchup file. There should still be an older ver attached to my build thread.*

Thanks, I have a 5 mb max limit on my email here (if it will fit and you have a chance). [removed] Also, in sketchup: Window > Model Info > Statistics > Purge Unused ...will let you save a version as a very small file. I gotta say again your room looks great! ~ Bill

Sketchup file and a few more pics emailed Bill.
