The BCK80 is  a the highest performance in-ceiling speaker in the Blucube range.

A two-way design featuring larger 200mm (8in) Kevlar bass/ mid range driver and a 1″ titanium tweeter this speaker offers a solution where more depth of sound is desired or where installation in a larger room is required.


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.
