A few days before Christmas 2023, this 1950's-era Samsonite luggage piece jumped-out at me/caught my eye at the Goodwill thrift store in Lynnwood, Washington.
i have no purpose for this luggage piece except displaying it as a gorgeous home furnishing, yet for only $39.99 i found myself unable to walk away.
Imagine my pleasant surprise when i turned it over to discover a full-range set of Sansui speakers!
And upon opening the suitcase, i find all the components inside are Made in Japan, including a 1970's-era Sansui SP-2000 Four-Way/Six Speaker board!!
In the pics, i've added only 2 things:
- Blue "post-it" Note where i mapped the wiring and Ohms resistance
- Below the Post-It, the Black Box is an amplifier ($56 AMZN) which i used to diagnose that:
- the board has 3 blown/dried-out capacitors that need replacing ($10 max total)
- the 12" subwoofer may need replacing (already got 3 JBL CX1200 spares, new sealed in box), then add a low-pass crossover or filter around 80-100Hz ($25)
- the 6.5" and 5" horn squawkers are good
- the two 2" tweeters are good
- the 1.5" super-tweeter are good
i also found interesting how the SP-2000 was not designed with 8 ohms evenly presented across all 4 channels:
- 12" sub is 8 ohms
- 1.5" supertweet is 8 ohms
- Pair of 2" tweets are 16 ohms each (wired in parallel halves the resistance to 8 ohms)
- 6.5" squawker is 12 OHMs, 5" squawker is 16 ohms (wired in parallel halves the resistance to 14 ohms!! this channel presents higher resistance so it must not be as loud as the other 3 channels, especially with channel power distributed across 2 squawkers, where the 6.5" w/ only 12 ohms resistance will be slightly louder than the 5" squawker which is 16 ohms..)
