Amazing subwoofer for the price

This high performance subwoofer should cost way much more. It definitely goes down close to 20 Hz and gives a nice impact. Great addition is a phase switch and dual bass reflex ports. Beautiful and well made cabinet gives a nice weight to it. Very happy with purchase and recommend.
