I bought this speaker for a project I was building, a little practice bass amp for my girlfriend, in the shape of a milk carton for fun. I used a different 4” midrange speaker facing out the front, and this woofer mounted in the bottom facing down, and it puts out a surprisingly strong WOMP for its size! Feels like a great quality speaker, I would definitely buy it again.
