ALEPH2

vitalica · 05:34 AM

Hi!
My Aleph2 - work and are very happy!

It exat what I wanted to search for the two Eminence Alpha15 "in Open Baffle-bass ... wonderful! Such precision and power I never once heard any!
After 3 hours heatskins (400x300x85mm)temperature is 50 degrees (Bias 3A) and
Uout - 3.1 mV and 2.9 mV.

Thanks to everyone on this forum for help, and especially Nelson Pass for this great amp!

Best regards,
Vitali

Very nice! I have, however, one reservation. The amp-stands have the same width as your amps. This could seriously limit the air flow through the heatsinks ...

What mesh have you used for the ventilation holes?
I need to do something similar, and am trying to get ideas.

I think a good idea to make a mesh of ventilation , but do not believe me

After five hours heatskins have 48 ... 50 degrees.

I use aluminum window screen material and epoxy. You can use a block of wood and wax paper to keep them flat and tight til the epoxy sets up.Then the wax paper peels right off.
