The unique and versatile Dayton Audio LW150-4 6" woofer was designed for ultra-low profile applications. Its low-profile frame and unique venting permit the back of the woofer to be placed directly against cabinet or even embedded (countersunk) into the cabinet, resulting in an enclosure less than 1-1/2" deep. Great match for todays ultra-thin TVs or use as a down firing subwoofer in a low powered system, low-frequency down-firing driver in a center channel/monitor stand, or bookshelf stand.
