One thing I especially like about the Twos is the lack of the "crossover" effect I've heard in a lot of high-end speakers, i.e. when the tonality of the speakers changes in different frequencies. Noticed this a lot when listening to solo violin and cello music. With the the Pi's, it sounds like the same instrument playing whether in the lower or higher registers.

Many thanks to all the posters here, especially Till E. for his woodworking and finishing tips. I made my speakers out of a nice piece of birch plywood, and have my Tried and True Oil waiting....

If you can, please post pics when you're done!
