Creativity is back... (BD-Design)

Hi Bert,

I had to register at last
How much db attenuation this filter correspond to? I'm going to simulate it with my test PC. This'll help me evaluate the Hemps as well.

Also, what is your opinion about "passive" filtering BEFORE the power amp? I would add a highpass filter at the same time in that case.
But I need to measure the drivers first and I havent received my Eathworks mic yet. My ears tells me of a rolloff between 200 and 250hz on flat baffles of 35cm width.

Also, the layout looks nice and I'm pretty sure that it measures better than a flat baffle. It should also be possible to integreate a ripole (4x32 cm vertical opening in my case) for the woofer in the bottom part making it less angled.

Regards,
Guido
