My parents have some old SL6 speakers that don't sound right anymore - they both sound really distorted. Both drivers still seem to work but they just sound bad. The speakers still look beautiful and I'm wondering if it is worth fixing them.Does anyone have any experience with fixing these speakers? Is it worth it? I think they are only worth about $350 nowadays.
I'm an EE so I could try to fix them myself if somone could direct me but I don't know anything about stereo repair...
Any suggestions or help would be appreciated.

If the drivers look good, it is probably a crossover problem.FYI, my brother has a pair of these speakers. There are very good monitors, and have satisfied many customers. I always enjoy listening to music at his house, and other than his speakers, I wouldn't consider his system to be very "high end." Unfortunately, there are very few drivers available for these speakers, so I wouldn't invest too much time or money in their repair.
Two cautions: if I remember correctly, the cabinets are actually made of aluminum, so make sure the crossover does not rest against the inside of the cabinet. Also be very careful with the tweeter, as it is very delicate.
If you determine that you no longer want the speakers, I may be interested in any drivers that are working properly.
I have a pair of the originals with the copper tweeter. The cabinet is wood. The SL600 had the "Aerolam" cabinet - this is a sandwich construction of aluminium skins with expanded hexagonal aluminium reinforcing. Much like the wing on an F111.

This can get involved. My suspicions are that of the crossover network based on what you are saying but..look down this list I am about to type...and or all of this can be the culpret.Have you changed amplifiers?
1. Rubbing voice coils with the woofers, tweeters.
2. Bad solder joints inside the enclosures.
3. Faulty capacitors inside the crossovers.
4. Poor connection terminals.
5. Bad resistors in the crossovers.
6. Faulty inductance coils in the crossovers.
7. Corroded loudspeaker cable.
8. Amplifier producing distorted sound.
9. Source producing distorted sound.I have had SL6 and SL600 celetions in the past. Nothing is really difficult to trace down since you have some education in electronics. The crossover is a simple LCR network. If all the connections internally are good and each driver plays clear outside the enclosure by bypassing the crossover (keep the volume exceedingly low when testing tweeters as they cannot handle more than a very low output on their own, reduce the bass control fully, keep the level low) then you have found the problem is the crossovers.
Very familiar with those loudspeakers.
