Boston Acoustics Single 2-way black Classic series bookshelf speaker

No surround sound home theater experience is complete without rear-channel audio effects. Serving up clear, full mid-range and low-frequency audio that's ideal for surround-channel sources, the CS23 combines a 1.0" tweeter and a 3.5" woofer driver. Further, a bass-reflex cabinet design enhances mid- and low-frequency performance. Finally, while magnetic shielding protects other A/V devices from electromagnetic interference, gold-plated binding posts offer superb conductivity.
