Got my spares from Martin yesterday, 4 drivers for the RL 140s and a lot of caps for the rest, ofcourse I had to start emidiately and the first thing was the crossover from one RL, changing the caps is easier than I thought, both crossovers was finished in 40 min. and its the first time I do it.

I assambled one RL and connected it to a 20 year old Sony reciever/amp, 2 x 10 wats, FM station and sound came out, sounded OK. Before I started the repair I tested with the same Sony and it was bad, distortions and with volume at max. the RLs did'nt play as loud as the original crab Sony speakers.

Today I assambled the other RL and connected both, there was a differens in the middle tones between the speakers, distortion in one speaker, audible even for me, my ears are old and tired, I started checking and saw one string of Rockwool insulation hiding in one corner of my garage, that string goes into the bucket where the middle tone driver is located, so open up again, add the rockwool string, connect again, and bingo, same sound in both, good sound even with this bad amp. and now louder and much better than the old Sony ones, I'm happy.

As I bought the drivers from Martin I have to give him some roses, these drivers are better than new, check the pic below, there is no signs of glue rests anywhere, the new surround fits perfectly and the drivers looks better than the original.

Ready to assamble, here I forgot to put in the insulation in the bucket, amazing what this little detail do to the sound.
