    Great woofer for both DIY and as a replacement.

    Overall: 5 out of 5

    I'm designing a component system for my car and needed an 8" woofer that could play well into the midrange to about 3khz or so. Bass wasn't a concern for me, because I have subwoofers, but just for fun I turned the subs off and set the crossovers to full range on these 8s. I was completely blown away by how much bass these are able to product from the door of my car. I would only expect bass that deep from deck-mounted 6x9s or a dedicated subwoofer. My crossovers are 12db/oct butterworth centered at 3hkz and these blend well with my 1" Polk tweeters. I'm very pleased with the price and performance of this driver.

    Good Woofer At Double The Price

    Overall: 5 out of 5

    I use these in lower cost 8" sealed two-way loudspeakers, and they sound better than they have a right to given the price. A nice low Fs provides good bass, and if the cabinet is smallish, go ahead and add an aperiodic vent to the enclosure. The midrange is a bit forward, but not unpleasantly so. I like this woofer better than the 55-1190.

    Great sound and value.

    Overall: 4.5 out of 5

    Wired 2 of these in series in a two-way with a GRS tweeter - all very inexpensive. Each woofer is in its own sealed box of 1.09 cu. ft. (3/4" MDF) and crossed over at 3000 Hz. Approx. .75-1.0 lb. fiberfill in each compartment. Powering them with Sony rcvr. (110W-145W per channel). They sound absolutely fabulous. I am very pleased and highly recommend.
