Hi Justin,
You must have been posting while I was writing mine.
The original Duetta was built with steel angle iron bracing top and bottom of the rear section like the Scintillas, and a simple 6dB/octave crossover and too attenuated at the top end so they sound dull. These are rare over here...
Hello
Thought I might join in as everyone is talking about my work :D
I would agree that Apogee planar bass is different to cone bass, but the new panels have better dynamics than the original ones, so they do have better attack and slam.
Also improving and changing the mid/tweeter crossover...
