The part where I don't have shop space anymore. ;D Lots of folks have mentioned the difficulty in tolerances with all the angles, especially if you have the secondary conical expansion. Mostly, I really like the idea of really nice fiberglass smooth contour horns rather than wooden square horns. That is mostly a looks thing but the smooth corners of the SEOS profile do have some benefits IMO. Note the SM60F has a smooth profile.

On the issue of the Synergy DIY project, I admit I haven't read the patent or tried to really digest what is going on. The part about the Synergy design that I understand the least is the mid and the location to the apex. I know it is suppose to be within 1/4 wavelength of the apex, but I am not sure how you determine where and how this plays into the crossover and preservation of phase throughout.

That part is the part I'd like to analyse in isolation for a given target passband. For example, what if I was designing a more traditional midrange horn and rather than placing the driver at the throat, I places it away from the apex as in the Synergy. What happens?
Click to expand...

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.

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!
