Enjoy precise highs and pure mid and low frequencies in your dialogue and music with your amplifier and the satin white Bowers & Wilkins HTM71 S2 Three-Way Center Channel Speaker. It features dual 6.5″ Aerofoil Profile woofers, a 5″ Continuum cone mid-woofer, and a 1″ carbon decoupled dome tweeter, plus two rear-firing bass ports. The included concentric foam plugs can be used to tune the bass output to your liking – leave the ports open for maximum bass response, or reduce it incrementally by plugging up one or both of the bass ports. The HTM71 S2 accepts 30 to 100W of power from your amplifier via its dual binding post inputs, and can be either bi-wired or bi-amped. The grey grille helps enhance the aesthetic of the speaker.
