Oh, okay. For some reason I gleaned that this for a more permanent installation. Sorry.
And for sure, if fiscal restraints are in place, you gotta start somewhere - been there, done that. Work with what you can and then get what you you really need when you can.
I pushed 14,400 watts into four VR-218s, (8 Low Max speakers), in a gym Saturday night and it didn't seem enough with 700 c razed teenagers screaming, but the venue management was happy, so okey-dokey.
To answer your question about "best boxes", the QW series boxes are engineered specifically for those drivers. If you are planning to replicate them through outstanding craftsmanship and woodworking, I salute you. I am not a woodworker and I would more than chew up the cost in Baltic Birch raw materials and "do-overs" in the structural support arena.
Best of luck,
Haha, well I'm bass crazy, but I've found my current Yamaha's did okay outside, considering I got the cops called on us...but those are less powerful than the Peavey's so definitely a lot more response will come out lol.
Is there anything particular to the inside of the box that would need attention paid to? Or is it just a basic ported box? Thanks.
