Polk Audio Atrium Sub100 10″ Passive Outdoor Subwoofer

Was initially worried ordering this as some say it was designed to only work well with Polk Atrium Sat300 speakers, but I connected it to a dedicated amp as a sub alongside my 4 older Proficient AW525 speakers and it gives the extra bass I was looking for on my patio. I preferred the sound of this over a Klipsch CA-800-TSW.
