leemelone Posted July 15, 2018 Report Share Posted July 15, 2018 The 2nd woofer has the surround installed incorrectly if I'm not mistaken. My OLAs have it inverted or flipped around. Link to comment Share on other sites More sharing options...
THD+N Posted July 15, 2018 Report Share Posted July 15, 2018 The surround on the 2nd woofer is installed correctly. It looks like the "roll" is toward the front of the woofer, but it is, in fact, going toward the back of the woofer. Link to comment Share on other sites More sharing options...
Pete B Posted December 10, 2018 Author Report Share Posted December 10, 2018 That woofer looks like it was completely rebuilt with a new spider. By eye, it looks like the cup section of the spider is too tall. A new bead of black glue can be seen at the VC joint. The Fs is quite high most that I redo with good foam and original spiders are 16 to 18 Hz. They should have an Fc of 41 Hz give or take a Hertz in system with fiberglass installed. All that I've refoamed fall into that range. The dust cap should be a coated fabric material, that one looks like the much later Jensen paper type.
