Buying notes
JBL three-way from the early 1970s. Woofer surrounds have almost certainly rotted and need refoaming; this is expected maintenance, not a deal breaker. Budget $90-140 for woofer refoaming. Check tweeter and midrange output. The Modern Classic reissue exists; verify you're buying the vintage original.
