The relationship (as I understand it) between cutoff and flare rate etc/high frequency output/circumference doesn't change much when there is an offset tap. Read the Synergy Patent it explains a lot...... As far as building it: Shop space...I wish I had an answer for you. The complexity with angles? Don't pre-cut it all, cut to fit...and you'll be a lot better off. Scott
Wow... Step away and miss a lot. Bill, I'm so glad to hear that you're in better shape than the doctor's thought. What a relief. Looking forward to your continued efforts here.
Bill, I have been watching these threads like a hawk waiting for the right project to come along. I have a CNC router 60"x 100" that I'd like to use to help the cause. If you need anything cut, and it can be shipped, please be sure to let me know! Joel (aka urapnes1 on avs)
