RE: Clarification of terms on Quad ESL-63s and their progeny
Posted by Artoa on March 5, 2017 at 15:58:47:
Quad ESL63 and more recent iterations have
- 2 panels with delay lines (full range).
- 2/4 bass panels, no delay lines, but added filter.
The low pass filter for the bass is a RC filter (360k resistor, panel makes the capacitance).
