Should I Re-cone a JBL L-65 Woofer ??

I am wondering if my investment would be in the right direction. I know that speaker technology has advanced a lot in 20 years, and that dollar for dollar, I would assume that you get more with current purchases. Speaker are incrementally better today. No. Some speakers now are better than some speakers were then, yes. Your speakers were never designed to handle digital media. Just what is it you mean by this? In addition the material sciences involved in speaker building has greatly benefitted from computerization which wasn’t available in the 70's. Otoh back then some manufacturers actually listened. Computer-optimization _does_ mean that getting the cross-over right is faster and that component count can be reduced. Today we can build better mouse traps but they often lack the aesthetics of the Jubal, for example. Agreed. How much more than the $450 would I have to spend to get something as good or better in today's market, and what recommendation of speakers would you suggest ? "good or better"... please define? Much would depend on your intended application? IMO $450 might be better spent on new (modern) drivers and crossovers, there are many source vendors. Assuming it is the 2405 equipped model, no tweeter replacement. There is no midrange unit replacent, a modernized version may exist but it will most certainly not be cheap. The bass units range upwards is extreme and it matches the physical cabinet, there is no bass unit replacement. What may be possible is to redo or tweak the crossover, I had my L100's serviced last year - before Quali-Fi, the classic JBL importer here in Denmark closed shop with new tweeter surrounds, new tweeter center-domes and a recommended cross-over modification. I recently did this with a pair of 70's vintage Altec speakers with ok (fair) results. Quali-Fi's result with my L100's was better than "fair", the obnoxiousity was addressed and the virtues maintained and enhanced. What you appear to say is that you replaced the Altec units, and cross-over and only kept the boxes? - You do not say what model it was, but in the context of the L-65 only lesser components are available, I find it probable that you had gotten better results by looking into the cross-over only and perhaps bracing the box.
