I have been working on these on and off since the summer. I finally have the cabinets built and a pair loaded for measurements for both AL and Be versions. The "Plan" is to use them as tops in a 1400 Array set-up. I hope to get my UBM "Universal Bass Modules" cut up and together this week. Can't wait to power them up and have a listen. That's going to have to wait though as I don't have the networks built up. As always half the fun is in the doing.
