Hey Rhodesj that is correct. Everything has to radiate from one face. That was a big factor.

Solidworks says these should be around 550 and they feel it. I can still roll them just barely. Used a couple shop dollies with 4" casters. Problem moving them was I had a fairly steep loading ramp...

Hey John. It's been a long road on this one. Logistically it was tough. When I finally got one fired up I was apprehensive. That's a big project and it has compromises. First off I was happy I wired...

I wouldn't technically call it a horn or FLH though. When I get back to my pc next week I'll post the inputs I have for modeling it. I'm out of town right now. Like the GH and...

Diyspeakerguy

I didn't mean to adjust parameters randomly. I only use BL and Le primarily in HR. Sometimes rg or Re slightly.

Motor design is not trivial and getting them produced is another hurdle. You'll find that it gets expensive. I worked on a uber motor/driver for myself for a few years when I had time. The cost would...

BTW I didn't mean that K20's have louder fans than K10's. Just that mine are way louder. Seems to vary quite a bit unit to unit. I wrongly assumed that they would be the same as...
