[QUOTE="tsenfw, post: 3520727, member: 581534"] Just bought a nice reconed RE SX off fellow site member, Qbenjamin. Sub looks in good condition but tested the coils with a DMM and here are the funky results: This is supposed to be a dual 2 ohm voice coil sub. 1rst voice coil = 2.4-2.5 ohms (stable) 2nd voice coil = 7-14 ohms (sometimes stable sometimes jump all over the place) Wired paralell = 1.9-2.0 ohms (stable) Wired series = 18-125 ohms (usually stable but different everytime i measure. was 18, 64, and even 125 one time i measured) Hooked up to home stereo wired in series on the low channel and threw in 60hz tone. Can hear tone from the sub ok. Don't hear any scratching or rubbing. What could be wrong with this sub? Loose wiring in one voice coil?! Did RE mess up the recone? [/QUOTE]
