Beovox P45 (Panel) Passive Loudspeakers

BeoVox Loudspeaker

Production: 1976 - 1980

Slightly larger than the Beovox P30 (and based upon the Beovox P50), the Beovox Uni-Phase P45loudspeaker was too an interesting design in that it was manufactured specifically for mounting on a wall. At 65cm tall it looked relatively large from the front although its depth was only 9cm. It was excellently positioned in Bang & Olufsen’s speaker range to be used with the new, equally-slimline Beomaster 2200 and the Beocenter 4000. Hanging in either a horizontal or vertical position (although, because of its slight angled front it looked better in a vertical position), easy mounting was made possible with its clever rear design.

The unvented pressure chamber-type loudspeaker was based around the Beovox S45 and S45.2 although was much slimmer. Inside were three main drivers: two 125mm woofers together with a 25mm tweeter (and phase-link unit). Despite its relative slimness, bass reproduction was good.

The two bass units were 8-ohm units from Peerless, marked 820809, and the tweeter was a SEAS H086, 25mm, 4 ohm, the same type as used in the Beovox M70. The phase-link unit was also from SEAS, the 10F-M

Connection was made by cable to its rear-mounted DIN socket.

The range of ‘P’ loudspeakers were useful and very flexible in their use. When they were retired from the market there was a gap of a few years’ until production of panelled loudspeakers began once more with Beovox 3000and Beovox 5000.
