Phone call with Phil Bamberg:
Yes, the woofers are Peerless aluminum woofers with copper in the motor. They are low distortion high rez woofers with a pure clear sound. There is a trap circuit in the crossover to control the cone ring.
The tweeter are a Scan Speak design. The faceted baffle smooths the tweeter response for improved, disappearing imaging. They are over achieving speakers and the cabinet finish is excellent.
The transition between the woofer and tweeter is seamless. The crossover is completely inaudible, leaving a singular unified sound.
This is a 2.5-way design meaning the lower woofer is rolled out early, leaving only the upper woofer to cross with the tweeter. This means the speaker acts as an efficient dual woofer in the lower range, but as a single woofer for best imaging in the high range.
Thank you Phil for clarifying this.
