Review on Dayton Audio DCS165 4 Classic Subwoofer by Eric Speers

I installed this adapter at a 45 degree angle in the space between the kitchen cabinets on the wall. I was limited by the space available, so size 6-1/2. I installed the speaker in a plywood trapezoidal tube that wedged into the space between the kitchen cabinets, turning the empty space into a punctured speaker box. The speaker and ports both shoot onto the countertop in my kitchen. This speaker is used to boost the bass from a pair of 10 inch in-ceiling speakers that lacked depth even at low levels. In short, it's amazing how that affects the sound. I am very happy with it.
