Of their products posted on ThingFling...
SP18 was their flagship "Hi-Fi series" with wood veneer, pyramid shape
WP2503 was apparently the lower end Hi-Fi with gloss black lacquer finish
AU265 was their Home Theater series with real wood veneer (fancy) and 2x Audire 6.5" kevlar woofers and Vifa 1" silk tweeter
DAC 2.6 was Home Theater series with vinyl veneer (cheaper) and 2X 6.5" poly midrange and an 8" poly woofer
UP series WAS an early model, discontinued around 2003? Can only find UP620 series info...
I could not find UP1203 in any of the archives of unisound.net, nor do I have any experience with any of these speakers.
