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...

John you are close.

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...

There's nothing wrong with looking at which amp will produce the highest voltage peak with various signals both simple and complex. The problem comes when equating it to an amount of power that will...

Hey Chrapladm.
Very basically inductance increases with coil mass and amount of windings. It also increases with the amount of steel in close proximity to the coil. The bigger the coil and larger...

No X series for me.
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...

Same choice I had. Go with less burst potential and less voltage into higher impedances or go with longer sustained current into low impedance. Pros for the 12K is it's cheaper and dead silent. Pros...

Every in depth study I've seen about vents/ports says the above is wrong. You want laminar flow. non-laminar flow= turbulence/compression/chuffing noises. If the above were...
