I bought these because I was installing a 10" mini active sub in my pickup. Due to the subs size, it can't handle ultra low frequencies. These filters protect the sub and keep the the sound tight and free of distortion. I was very impressed with my mini subs performance with these filters installed.

Works great out of box, my old speakers were being ruined by subsonic rumble and these fixed the problem for cheap.

Used this as a rumble filter for my Technics SL1200 turntable since my amplifier didn’t have one built-in. While it did reduce the subwoofer pumping, it muddied the sound quality of my records.
