Watch for updates though, because I've been working on upgraded crossovers for some models.
The cable assemblies for the tweeter are labor intensive, so I decided to have crossover PCBs made that have room for them. While I was at it, I made room for various configurations and possibilities. The board is 6" x 12" and has room for a two-way or three-way circuit. The tweeter circuit can be made 1st, 2nd, 3rd or 4th order, depending on how it is populated. The midrange (or midwoofer, if two-way) circuit can also be made 1st, 2nd, 3rd or 4th order. The woofer circuit can be either 1st or 2nd order. In addition, the mid and tweeter circuit has room for attentuation resistors, with the mid being a traditional pad and the tweeter being the same R1/R2/C1 form as used for the past few years. The mid attenuator has room for a bypass inductor, as is used on the eight π speaker. So this PCB is very versatile, and will make building my speakers and kits much easier and better.
