THE BIG 10-INCH (WOOFER CABINETS)
These are 4 identical speakers, but finished with 2 different finishes. Each use a single 10" driver (Audio Concepts AC-10) in a 1'st order sealed configuration. Each driver cost $55 ('90). With no internal crossover, they're used as woofers with the flexibility that external wiring allows (to different/ seperate amps etc). They're similar in look & size to the Advent speakers of old, although these are only woofers & use a different (compliance) driver.
