Posted August 16, 20214 yr Been using CSW Model6's in my home gym for the past year. While they were good enough for the $25 I paid for them, they have their weaknesses and roll off hard at 100hz. I've had some Coustic Design Reference 7" mids sitting around for about a decade. Despite being car audio mids, they're old enough that they actually have more home audio TS parameters. Figured I'd put them to use and gain some more DIY experience at the same time. Trying to ball on a budget here as these speakers aren't uber important, more of a learning experience than anything. Decided to go with a Woofer Assisted Wideband arrangement for a couple reasons. First I wasn't sure of the usable high FR of the mid but I'm sure with the ancient technology involved it's going to be unimpressively low. Second I was trying to really pinch pennies here and getting a ($10-15) cheap tweeter that will play low enough to mate with these modbass was unlikely. The Vifa TC9, however, is only like $7 and will easily play down near 100hz if desired.
August 16, 20214 yr Author Popular Post Mids modeled well in .6cuft tuned to 46hz. I'd have to look again but IIRC the F3 was in the high 30's. Since the TC9 has an odd shaped basket and a front mounted gasket, decided to rear mount the widebander. Plus I think rear mounted drivers just look pretty freaking cool Learned a lot building the 7empest speakers last year, both acoustically and woodworking. Much happier with the quality of the craftsmanship of this enclosure. Hope to keep improving a little each time. Just waiting now to get my mic back from getting calibrated. In the mean time only thing left to do on the speakers really is decided on color scheme and paint them
August 16, 20214 yr Sweet. I just put in a new patio. Contemplating what to do for tunes there. I MUST build something soon.

September 12, 20214 yr Author About ready to start measuring, finally. Wanted to this weekend but didn't have the free time I thought I would. Just got them to this point a few minutes ago. Must say I really like the look of the rear mount with roundover on the wideband. Wish I would've swapped the port on the right speaker so the port was on the outside on both. Not that it matters acoustically. It's purely cosmetic. Just would've been nice to have the forethought to plan that look better.
