As the owner of a ’vintage’ (1960s - 1970s) system I have tried many from that era; including the more well-known such as JBL L-100s, Pioneer HM-100s, as well several from University, Altec, Dahlquist, Vandersteen and Bertaghni brands...
Ended up with a couple of surprise picks from, of all manufacturers, Sansui.
SP-5500 and SP-5000.
The 5500s are the truest ’diamond in the rough’ and are both extremely rare and massively underappreciated. 110 pound monsters with a 15" woofer, 9.7 pound AlNiCo magnet and solid brass bobbin; a 17" aluminum tig-welded midrange horn, and a pair of JBL-sourced tweeters... the ’presence’ and detail of that midrange is something I have not yet heard on even modern high end speaker systems. Bass is more than adequate; strong down to 32 Hz - yet subtle and not boomy at all. Upper end response is crisp and clear up to 22,000kHz... cabinets are true 1" MDF around a plywood frame, with real maple veneer outers and a hand- carved rosewood grille. Absolutely beautiful pieces of furniture.
The 5000s are a somewhat close second with many of the same features as the 5500s - although cabinets are 3/4" MDF vs. the full 1" on the 5500s; and the 5000s make due with midrange cones vs. that magnificent horn on the 5500s.
Absolutely flies in the face of the generalization that "...all Sansui speakers suck" and are tailored more for Japanese classical music (or American jazz) than for other musical genres.
My friends in the audio world that have experienced my system in person are at least somewhat impressed by things like the Dynaco tube preamp and the mono blocked pair of MacIntosh MC2100 SS amplifiers... They appreciate the pristine Reel to Reel equipment; the decent linear drive turntable, etc. but often look at the speakers with some disdain. Until they hear them, that is...
Then the questions fly:
"Where have you hidden the subwoofer(s)?" there are none
"How much EQ are you using?" none
"Are those the original drivers in those Sansui’s?" Yep, 100% original
Then they exchange that look of disdain for a look ranging from pleasant surprise to outright shock.
That’s when I know that I have made the right choice.
