philcryer Posted September 25, 2012 Report Share Posted September 25, 2012 I bought a pair of AR-4x speakers that had a newer tweeter in one cabinet, and corroded pots on both, so I decided to rework the pair. I utilized new phenolic ring tweeters - 8 Ohm (http://www.parts-exp...tnumber=270-252), new solen 20uF 400V polypropylene capacitors (http://www.parts-exp...tnumber=027-582) and new L-Pad attenuators - 15W Mono 3/8" Shaft 8 Ohm (http://www.parts-exp...tnumber=260-248) in place of the corroded pots. While the high end is now very well defined, I'm missing the bass that made the speaker sound so full and smooth before I started working on it - overall the sound is very thin. Did the pots contain some sort of resistor that I'm not taking into account with the new L-Pads? Am I missing something, or should I fix the pots and use them instead?As an aside, thanks to all the contributors to this site who make this learning experience so much fun, this will not be the only time I open up 40 year+ old speakers, next up are some KLH 17's!Phil Link to comment Share on other sites More sharing options...
