Article: Purifi PTT6.5 Woofer and 1ET400A Amplifier Technology Review

[all300b]

Wow - such a great idea to focus on perfecting the 6.5" woofer.  The two-way rises again.  Any thoughts on:

-  What about trying a sealed box configuration?

-  Could this go with a first order crossover to something a little softer - say like an Esotar? The freq response curve for the pure-fi looks remarkably free of of ringing - it might not squeal when asked to play some higher notes.
