A friend asked for a rig because the commercial offerings were just out of reach financially. Six kids will do that! Well, its speaker building and an area that I was not well versed in, so yeah, I will give it a try. After much searching, reading, and modeling I decided on this concept. A pr of Eminence S2012 woofers and a pr of PRO5MRN-8 mids. The crossover point is 2khz and the mids are wired in reverse polarity. I used 2nd order electrical slopes, damped on the woofers, on both sides. No BSC in this design.
The cabinet is on the large side at 6cu ft but the light weight neo drivers, 3/4ply and minimal bracing keeps the weight down. Overall dimensions are 31.5w 24h 17.75d. The 4" ports tune the enclosure to 40hz with an f3 of 50hz. This is low enough for a 4string bass and on the edge for a 5 string.
Many of the commercial offerings employed a tweeter, but really would have a pretty nasty null between woofer and tweeter. Most just run the woofs full out, break up and all. Kind of silly imo. Anyway, while the response here is not as smooth as we are used to seeing from our projects, it is much better than the commercial offerings I tried. Sitting directly on the floor, the bottom end is rich and full so no worries there!
