I built the 2PI Tower last Fall and since then, have replaced the KSN1038 with an Eminence APT80. Now, I'm thinking of relieving the Alpha10 of its midrange duty by replacing the APT80 with an PSD2002 and crossing over at 1.6K. The Alpha10 sounds good, but it's got a big job, working from 40Hz to 3.5K and beyond. I like what've heard from the 2002 and thought I can bring some of that to my speakers. Besides, if it works for the Thermionic Studio 3, why not for my 2PI?

A couple of things I'd like opinions on:

Am I totally off base with this tweak? If anyone thinks that I will not hear any improvement at all, appreciate it if you can share your thoughts.

In terms of crossover design, would there be a better starting point than the Alpha12/PSD2002 description in Wayne's crossover document? The Alpha10 and Alpha12 response curves are so similar. The both even have the same dip and rise between 800 and 2000 Hz.

Gar.
