Don't overlook a whisper!
BeoLab 7-4 adds realism to any film or television experience. Utilizing the same acoustic lens technology as the BeoLab 5, this small yet powerful speaker is particularly designed to recreate the sound of voices. This is critical in a surround sound setup since the center channel carries 80% of the voice information. You won't miss a whisper the next time you watch a movie.
Surround sound centerpiece
In a surround sound arrangement, the BeoLab 7-4 is intended to deliver a strong performance in the crucial center channel. It may be used in conjunction with any BeoLab loudspeaker and the BeoLab 2 subwoofer to provide the ultimate surround sound experience with the BeoVision 7-40 LCD or BeoVision 4 plasma televisions or a projection screen. Moving with your BeoVision 7's motorized floor stand, the BeoLab 7-4 gives a new layer of sound to whatever you're viewing on TV.
The vertical architecture of BeoLab 7-4 ensures the finest possible tone balance in speech. Deep bass tones are filtered out, resulting in higher power output and allowing the BeoLab 7-4 to play up to the maximum possibilities of the BeoLab 5 loudspeaker. The acoustic lens, which is centered directly under the screen as a visual accent of refinement, guarantees a tonal purity experience in the horizontal plane. Regardless of where you are situated, the sound of voices becomes highly genuine.

Any idea how to change to voltage?

[@KoseTrading]

I'm not sure, but maybe you can change the pin and set a jumper on the power supplier board. Send me a e-mail and I can guide you.

Anyone know how to bypass the 50hz high pass filter?

Hi. Thank you for your message.
No, I do not know that process

Hi. Ever disassembled a pair of beolab 12-3s? Would be interested in seeing that. Cheers!
