Expanding on the original topic of this thread, I'm in the process of constructing two 22" cube boxes for the living room to replace my recently sold Epik Empires. Each will house a single 18" SI D2 driver, powered by an EP4000 for now. I'm currently in the process of 'selling' the idea of adding two additional boxes/drivers (for a total of four) to the rear of the room to the wife.
In which case I'd be using one channel of my spare clone amp or the XLS5000 to power the quad 18s. Room size is 19x20 with high ceilings - and of course sitting on a suspended floor which makes for some real fun.
I get some decent room gain in there but will still need some EQ.
Build Notes: This was my first time cutting oversized panels (1/16th to 1/8th) for the top and front baffle which kind of seems like a waste considering I took a good deal of care to make sure all the cuts were spot on. The bracing was kind of a PITA to line up everything but appears to be very rigid. The one annoying thing about the centerline vertical brace is that I cannot place my connectors in the middle of the box. I may add in one more horizontal brace on each as well. I cut both outer baffles at once which made things very easy in terms of alignment. I'm excited about having speakon connectors on these vs. the bananas on my original dayton boxes. I may be updating the original boxes to use these as well.
Some box specs:
- 22" Cube for just about 4.25 cubes net including driver displacement and bracing
- 7 Ply 3/4" Birch plywood construction
- Triple front baffle to allow for grill use with the large surround
- Cross style horizontal and vertical bracing
- Recessed speakon connector
- Duratex finish
- Magnetic based grills based on original design but in 1/2" thickness. Will also experiment with splining method of attaching grill cloth
Before outer baffles are added.
The pics are slightly out of date but more to come. I currently have the front baffles glued on and will be flush trimming the boxes tomorrow night. Should be prepping and paint this weekend. Going to do a duratex finish on these guys as well. Edited by Gorilla83 - 5/21/13 at 10:43am
