Re: professor plum's cabinet dimentions for A-25 - woofer cap?

Posted by freddyi on June 9, 2002 at 14:30:27:
Hi Charles - nice - did I miss something - see 5uF cap listed across woofer - without a series choke, input Z would drop very low at HF (like 1.6 ohm @20Khz due to XLc, that in parallel with woofer voice-coil Z) - I've done this accidently once by placing a cap before an inductor
