#12 in a series of articles about the technology behind Bang & Olufsen loudspeakers
As I mentioned in an early posting about two months ago, if I didn’t have time to write enough, I’d cop out and post some photos of development models of some of our loudspeakers. It’s been a busy week. So, here are some photos of the BeoLab 18 and BeoLab 14.
Early BeoLab 18 prototype. This photo was taken on the floor of the Cube.
Early BeoLab 18 prototype – acoustic lens closeup. The lens itself is an SLA prototype and is attached to the top of the milled plastic cabinet using modelling putty.
Early BeoLab 18 prototype showing a closeup of the port. More modelling putty was added to the bottom of the port opening to smooth the curve as part of an investigation about reduction of turbulence noise.
The first BeoLab 14 prototype – subwoofer and satellite. Note that the DSP and amplifiers would be external for this prototype. The white modelling putty at the top of the pipe used to port the cabinet was put there to reduce turbulence noise. It is not a prototype of the final geometry of the port flare – it was just a quick-and-dirty solution for the initial demos.
