[QUOTE="Art Welter, post: 218036, member: 52"] As shown, the woofer circuit looks like a 1st order crossover L1 with a Zobel comprised of C1 and R2. At high frequencies, C1 effectively becomes a short, putting R2 in parallel with the driver, dropping the impedance below 2 Ohms, probably burning up and needlessly wasting power, unless using a 2 ohm woofer. Looks odd. The head SpeakerAddict is: [email]Cameron@speakeraddict.com[/email] Phone 562 972-5992 Maybe he has an explanation of why R2 would be so low. [/QUOTE]
