Posted February 16, 200817 yr Hi Fi...I have (2)Audiomobile Mass series motor structures. no frames or top parts, just the magnet strutures. They are(were) 3inch underhung dvcs. Can they be rebuilt at all? They don't have to be dvcs. I would actually prefer single 4 or single 3. They need whole new top assemblies and softparts. Can this be done...ballpark cost for 15's. Thanks for any info.
February 16, 200817 yr How tall is the top plate? I'm not sure if we can do a under hung design or not, but i know we can re-cone those motors.Thanks!-Nick
February 16, 200817 yr I'm not sure if we can do a under hung design or not Aren't the Brahma and Avalanche underhung XBL^2? Or do they use different size coils?I measure a 32mm top plate on my SVS Ultra driver which is an Audiomobile motor attached to an Eclipse Ti frame.-Robert
February 16, 200817 yr Author SVS had (2)versions of the Ultra. My Audiomobiles were the same as the sub on the left. I'm not sure how to measure the top plate. Is that the verticle distance inside the magnetic gap? From the bottom of the inside of the motor to the top? Let me know what to measure and I'll post the numbers. If the motors can be reconed, how will not having underhung coils affect the SQ of the driver. I know a lot of drivers magnet structures are designed/built specifically for the coils used. If I go with another coil will it still sound good? The original sub specs stated a 25mm Xmax. With a conventional coil am I still looking at that sort of movement range? Thanks again!

February 17, 200817 yr I have the version on the right.I measured from the bottom of the frame to the top of the magnet slug. The silver hunk of steel between the magnet and frame is the top plate. You should also measure the depth of the motor from the top plate to the bottom plate inside the gap. I used a thin piece of cardboard to get the full depth of my TC9 motors and then just measured where I made a pencil mark on the cardboard. My TC9 motors were 75mm deep. 12mm thick top plate. A pair of 1" thick magnets are approximately 51mm. Then the bottom plate is bumped out about another 12mm. I think your motor and the TC9 share the same back plate so your motor would only have about 36mm of movement from the bottom of the top plate to the back of the motor. -Robert
February 21, 200817 yr Just a bump and more info.I pulled the decorative magnet cover from the magnet slug and there's an Audiomobile 2012 sticker on the side of the motor.-Robert
