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
