Dayton Audio LW150-4 6" Low Profile Woofer 4 Ohms The unique and versatile Dayton Audio LW150-4 6" woofer was designed for space limited, minimum depth applications. Its low-profile frame and unique venting permit the back of the woofer to be placed directly against cabinet walls or even embedded (countersunk) into the cabinet, resulting in an enclosure less than 1-1/2" deep. Great match for today's 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.
