Greetings one and all,
I have been following this forum, with great interest, for some time. This is my first posted question. Not that I don't have them, but in searching this forum, you guys have always shed light on whatever seemed to be my interest at the time.
I have acquired a pristeen 2245h to use as a subwoofer. In checking it out, it has a 5.0 volt
resistance across the voice coil. Applying an AAA battery voltage with the cone facing up, I get a scratching sound (just like other woofers I have tried) and plenty of cone movement.
With the magnet facing up, I get the same sound but no cone movement. (Neither pos. or neg.) In moving the thing around, I can hear a distinct rattle. Something is definitally loose in the magnet assymbly. There is no foilcal or screen covering the voice coil hole, just some spongelike material inside.
I would think that anything steel would stick to something inside the magnet. I really don't want to power this thing up and destroy the voice coil. How do I take it apart without ruining anything? Can I pull the spongelike material out and put it back without damping the cone movement? Anyone have any suggestions?
Thanks so much.
Stevedel
