These 8" subs were a GREAT addition to my system, and give the perfect balance for what I wanted in the sound. Not only do they respond lower than the average 8" sub, (down to 26 hz), to get that nice low bass; but they hit really hard and give a nice crisp 'punch' to maximize the overall bass experience. Great sub, great price, and great quality... Most people look for ways to cut-corners when looking for subs, thinking that it's all just "bass"; but you really DO need to be particular if you truly WANT that stellar-experience. Hats-off to the Polk MM840's.
