Gold Plated terminals will accept 14AWG wire Frequency Response 40Hz-22KHz Sensitivity 89dB at 1W/1 M Recommended Amplifier Power 10-150 watts Impedance 4ohm/8ohm selectable on PCB Cut out size 244 mm Description BIG BRAND PERFORMANCE AT AN EXCEPTIONAL PRICE. An outstanding speaker with an 8" woofer combined with midrange driver to give the ultimate performance and bass response. With titanium tweeter for crisp treble. Recommended for larger rooms and where more bass response is desired, or main listening rooms. Attenuation Switches Each Blucube custom install speaker pair, from the BCK range, features 6db attenuation switches for both woofers and tweeters. These allow the installer to fine tune the speakers output levels to match room designs, specific applications, or individual listening preferences. Adjustable Impedance The 4ohm/8ohm switch located on the PCB provides the installer increased flexibility in matching power output and impedance levels to optimise the systems performance. Woven Kevlar Cones The BCK series of custom install speakers use DuPont Kevlar fibres. The woven Kevlar fibres used in the cone allows the woofer section to deliver better defined bass and at the same time producing a refined midrange bringing a cleaner, clearer listening experience. Titanium Tweeters The titanium dome tweeters in the Blucube BCK range deliver a smooth, crisp, controlled frequency response with detailed sound. They are able to handle more power and definition more consistently than soft dome tweeters and are protected by a polymide auto-reset switch in the event of overload. With a 30-degree tilt and full rotation swivel capability, the tweeter design allows for a tailored and optimised performance to match room design, or layout. Stable Mountings The two-piece baffle design in the Blucube custom install range allows the tweeter to be directly mounted on the bridge itself rather than the pole mounting found in most current designs. This allows the speaker to handle more power with increased cone stability resulting in reduced harmonic distortion. Durable Construction All speakers are designed to deliver excellent performance in a full range of indoor listening environments. Polypropylene plastics and large cable gauges, for better signal transfer, will ensure many years of listening enjoyment. Blucube speakers carry a 5 year warranty.
