Bang & Olufsen's innovative BeoLab-11 sub-woofer
April 19, 2010
Bang & Olufsen has added some serious bottom-end to its speaker line-up with the BeoLab 11 subwoofer. Sporting a small footprint and typically slick design, the tulip-shaped BeoLab 11 unit uses two opposing drivers to take advantage of the "Acoustic Balance Principle" - a first for B&O in subwoofer design.
The BeoLab 11's aluminum outer shell contains a built-in 200W ICEpower amplifier and two 6.5-inch drivers which deliver sounds in the 33-125 Hz frequency range.
The advantage of the tulip-shaped cabinet - apart from the great aesthetic - is that the two drivers are placed in opposition to produce "in-phase" frequencies which "effectively eliminates almost all unwanted vibrations from the unit" according to Bang & Olufsen.
The design also lends itself to versatile placement options not catered for by most sub-woofers.
“Thanks to its acoustic principle, which reduces to a minimum the vibrations normally experienced from a subwoofer, BeoLab 11 can be placed either on the floor or can be hung on a wall – and it will offer great performance in either position. Hanging a subwoofer on the wall is quite unorthodox. However, in many home environments this may be the preferred placement, as it will be possible to hide the cables and it will free up floor space,” states Michael Jensen, Product Manager Bang & Olufsen.
