JBL model L150 woofer cone color question

The black and white cone versions should be the same sonically if they have OEM cones, have been re-foamed properly and if everything else is in order.

I don't know how this would affect resale value.

I moved to the Los Angeles area in late 1977 and saw many of both floating around for many years, along with tons of D130's.

The L110 and L150 were the first JBL's that I liked the sound of (aside from a Paragon that I heard years before).

Just cruised Youtube to see if any L150's had black woofers (didn't see any) and come up with this (custom cabinets).

I sold these JBL’s a long while back and never saw JBL black woofers. We also saw a lot of blown JBL speakers, usually someone who had a lower powered amp they turned up to high. I would say they were replaced. If they are JBL replacements, no real problem. Another brand replacement and they will not sound the same. That could be good or bad, no way of really knowing.

Most large JBL woofers are paper fiber cones that are easily replaced although you always want to do both sides, so they are matched, even if you are replacing with factory repair kits.
