Summary: This three-way design from Alpine is the best bang for your buck. As a professional musician and semi-audiophile, I have a very demanding ear and these speakers deliver quality sound in every range including a very punchy bottom(thanks in part to the empty trunk) and crystal clear mid and high ranges. Granted, I don't like to listen to music extremely loud and don't require a sub-woofer for the style of music I listen to-i.e. jazz, classical and classic rock.
Summary: A quality product delivered well-packed and quickly. I purchased this product because of a recommendation given to me by a pro-installer. The price at which I purchased it was nearly half of the figure quoted by a local brick-and-mortar store; couldn't pass that up.
Summary: After a difficult installation, I finally got them in. At first,I wasn't sure if they made any difference. But after I sealed them in, Boy what a differance. Deep solid bass, Think well amplified 10" subs, Solid!! There was some noise the first couple of days, but after they settled a bit, they sound great.
