I just want to share photos and impressions of my latest find, a Sansui S-alpha 9 speaker, data of which are hardly available online. I don't think this is an exceptional speaker, definitely not made for the alpha 907 series amps, but it was likely issued in late '90s -- current resale value in Tokyo's hifi online auctions from $100 to $150/pair. Sansui was an amplifier company and never re-established its reputation as hifi speaker manufacturer since it ended partnership with JBL in the '70s.
I got this, without tweeters, along with a cheap black Pioneer phono (PL-A350B), an upscale Sony tape deck (TC-K555ESx) and a multi-disc Pioneer CDP (PD-M50) for P5k from a junk shop here in Davao. Luckily, all four are working well now, but the S-a9s needed rehab. Found a pair of classic Bill Hecht (PhaseTech) soft-dome tweeters in my storage room, which fit the S-a9 holes. It's been in service for at least a week now.
Sensitivity could be in mid-90s (db) as it mimics large speakers. It plays louder and produces fuller sound compared with, say, the vintage Celestion SL-6 (I still have the original 6 and its successor, the 6s) whose sensitivity is at low 80s (db). S-a9 is a bit larger, actually deeper by about 3 inches, than the SL-6 and the KEF-101. The good sound, however, breaks when played as loud as my JBL monitors. At least, the Celestions and the KEF (even the Epos 14) don't lose their character when played very loud, but they do exhibit inferiority compared with the heavyweights at live concert SPLs.
Anyway, here's my newest toy (with the candy-like look):
