For your consideration is this genuine 8 poly woofer used across a few models in the 1980s Reference Series of speakers (not to be confused with the 1990s series with the same name, which is not in the same league quality-wise or sound-wise). Removed from a working RS8 speaker. From my limited research, compatible models include the RS4b, RS6b, RS7b, RS8a and RSe. This is the family of speakers with EMIT tweeters and polydome mids. Good cosmetic condition. This one was professionally refoamed a few years ago so the foam is solid. Impedance measures a healthy 4ohms, in line with factory specs. Part number is 902-4976 or 902-4978 (hard to tell). Dustcap is intact too. Picture of speaker is for reference only. SPEAKER CABINET OR TWEETER ARE NOT INCLUDED, only the woofer is included in this sale. Quoted shipping rate applies to destinations in the continental US only. If outside the lower 48, please reach out for an exact shipping quote. The speaker will be carefully packed, double boxed, surrounded in foam to avoid damage in transit.
