On offer are a Acoustic Audio PSW 10 400 Watt downfiring 10in sub (top in pictures) and a front firing Polk Audio PSW202. They add some hearty thump. in the bass region and can fill in for bookshelf or tower speakers that need some extra for music or movies. They both have speaker wire input and output to set crossovers so there are no frequency overlaps with mains. The Acoustic Audio PSW10 has a small amount of vinyl damage so $70 by itself. Polk PSW202 seems to be in good shape and is $80 by itself, but I am willing to offer a deal for both for $140, which is a pretty good price to add 2 ten inch subs and run stereo with crossover control. They both perform as intended with no problems and will provide some nice thumping for a pretty reasonable price. I am in Ascension parish but frequent BR often.
