REL ACOUSTICS BRITANNIA B3 SUBWOOFER. Original owner, smoke free home. This item does have some sort of issue (muffled sound) that needs to be repaired. It is probably the woofer/driver or the amp module. An approximate cost to repair it (with labor) is $600 for the woofer and $950 for the amp module. This subwoofer does not have the original box. I've listed the condition as a 4 due to it needing repair, but it is not in "mediocre rough shape" as 4 describes. LOCAL PICKUP ONLY.
