This pair of 4-1/2" bookshelf 2-way speakers have a newly-designed 4-1/2" polypropylene cone woofer with a 4-layer voice coil. When combined with the 5/8" ferrofluid-cooled polycarbonate tweeter, this pair of speakers produce up to 60W maximum of excellent balance and listenability for surprisingly rich and detailed sound. These speakers use a fully-sealed wooden cabinet finished in a black vinyl with removable grill that minimizes resonance and enhances warmth without sacrificing clarity. The speakers are 9.5" H x 5.5" W x 5.7" D and include wire and wall mounting brackets.
