Hi, this is a made in Canada, beautiful looking and sounding, Energy RVS-1 Center Channel Speaker. It uses Dual-Vent QB3 Alignment, a Point Source Driver Configuration. 25-150 watts, 4-6 ohms, sensitivity 88 dB (anechoic) @ 1m/2.83v. All I can say is that it sounds great, and with its black piano finish, it is quite eye catching. It's 8.25 inches high, 19 inches wide, and 11.5 inches deep, and quite heavy. Just $60, or will consider serious offers. Please email, call, or text 613-617-6456 to audition it, thanks.
