I completed (not finished because the cabinets are bare MDF--not even sanded yet) my 2 Pi's a few days ago. The tonal balance is off as described in the "piezo shout" thread above. To me, a complete newbie, the Delta 12-LF's high frequency roll-off looks like a better match to the 1038 than the Alpha 10-A's. Also the Alpha 10-A has a hump between 1K and 4K, whereas the Delta 12-LF has a smaller hump between 2K and 3K. So I thought I might try a cross between a Studio 2 and a Theater 3.But I will try slightly attenuating the 1038's and damping there plastic horns first.
