I have two pair of SP-2000s, among other speaker systems (7 total). I'm using one pair and the other mint pair in the boxes in the closet. Cabs don't even have a fingerprint on em. I think they are as close to brand new as you can get.
I really like them. The pair I'm using sounds really nice. Not bad for 40 year old untouched speakers. They sound 'so good' I wouldn't even consider taking the backs off to do 'anything'. They sound just fine as is.
Are there better sounding speakers out there...yes, of course. No matter what speakers you have...there are better speakers out there. Are there worse sounding speakers out there...'no doubt about that'. SP-2000s do sound pretty nice. They have the big box 1970 Japanese sound, alnico magnets, cloth surrounds-never rot, and are pretty bullet-proof. And for the price they sell for on eBay used, generally $100-150 for a really fine pair, ... it's pretty hard to beat and a great value for the money for sure. Think new they cost $1000+ in 1970 dollars! that would be about $3000 now. I just like them...'but' for someone who didn't have a big budget for stereo speakers these would be gems. You just have to find a pair that works and sounds right. that's the biggie. It's really good if you can listen to them before you buy. They are 40 years old.
The cabs are of a very quality construction, are very heavy, and look cool too, if you into the wooden grill box speaker Japanese look of the 70s. They look like fine furnature, and they do have that heavy big box alnico magnet speaker sound. Crank em up and they handle it real fine.
They are ok, I'm very happy with them. One thing I really like about them is that they, to me, sound very natural, lifelike, comfortable. But as with all speakers, the sound depends on the person listening. I have a pair of Sansui AS-300s that need to be restored, and I'm kinda speakered out right now, but if I was to purchase 'another pair' of speakers, someday, they would be JBLs.
SP-2000s function, look, and sound very nice. That's it really, and there is a ton of info on AK on 'restoration of the crossovers' if you desire to do that. There is so much information it's a no brainer...just do what the guys say and your crossovers are restored.
Love or Height: it's up to you. Some guys really hate Sansui speakers and are knocking them all the time non-stop. Guess they never had a nice sounding pair. Now on the other hand, some guys, like me, really like Sansuis and think they sound pretty good. They do.
But not all Sansui speakers are created equal.
By in large, the 1970s Sansui SP-200/2000/3500 (among a few other models), the 1970s AS-100/300s, and the SP-L series were the good ones. The others I really don't know much about but many of them, from what other people have said, don't sound all that great, and that may of been why people don't really care for Sansui speakers in general. The very early 70s speakers, like the SP-2000s or SP-200s, with the alnico magnets are good.
