Ok. I just need something that can generate test tones on a mac. No sound card needed: mac --> optical out --> Buffalo III SE --> amp ---> pepperpot. But your measurements from the HPD probably carry over so may not be needed in the end.

I use REW on my Mac for signal generation. Seems to work fine.

Just installed. I think the sine wave sounds better than the square wave. ;-)

Probably easier on your drivers as well.

Nelson, do you think the new active xover will have suitable adjustment to level out the dip in the mid range respose of the attached plot?
I currently use a shelf filter in minidsp to drop the FR below 4khz.

I'm sure your active xover will be a lot better than minidsp....

Many thanks, Dave
