I purchased a pair of Sansui SP L700 speakers from an eBay auction about a month ago, and was really excited to get them as they looked like they would be a very good sounding pair of speakers. When I got them and hooked them up, I was quite dissapointed with there sound, so I decieded to attemped to restore them and hopefully they will sound a lot better. They lacked bass IMO having twin 10 inch bass drivers and a single horn behind an acustical lens, I thougth they would be a nice change from my usual speaker by being an easy to driver with a smaller nice amp and pre amp, without the need for such a large expensive amp that my other speakers all require. I will take a lot of pics and let everyone know what I think when done. I could only take two evenings of listening to them before I removed them from the system. Other than looking nice, and being built very well, they sounded very bad. Sansui SP L 700 manufactored in 1976 cost 210,000 yens, or $2,303.00 per pair. Pulled the two bass drivers out, I couldn't tell that one of them the foam had pulled off the bass cone, the foam surrounds on these, glue to the back of the cone rather than the front, thats good, I won't have to worry about any glue oozing out on the front of the cones when I refoam them, hope to find the right foams, that might be a bit harder. Pulled all the bass drivers out, one where the foam has split off the back of the cone. All the baskets are cast, nice size magnets, Bass tuned port made of wood goes along the bottom and then turns up the back, all the sound deading material is fasten to the sides Crossover looks pretty simple for a recap, looks like only two caps pre pretty decent sized ones. couple of resistors, and some inductors.
