Bang & Olufsen - Beovox S55 Passive Loudspeakers
VENDU
Beovox S55 was an ideal bookshelf speaker, but could also be used as a wall-mounted or free-standing model with the optional fittings available separately.
The pressure chamber cabinet contained a 21cm bass driver, an 11,5 mid-range/phase-link unit and a 2,5cm tweeter. Power handling was 55 watts RMS.

IMF - TLS 50
VENDU
The TLS 50 II retains the full transmission line loading of the Monitor loudspeakers.
A transmission line provides for the driver a near ideal acoustic environment and the reputation of the TLS for low colouration and extended bass performance is well established.
The TLS 50 II employs a bextrene cone bass unit with large pole and huge magnet, allowing long excursions without distress or undue overhang.
The quality of the bass response is very special. ‘Line’ bass is different from the ‘box’ bass of conventional speakers. It is free, more dynamic and exists in space rather than in an enclosure. The bass line forms a pressure loading device so that low frequencies are felt, rather than heard.
Both the TLS 50 ll and the ALS 40 II employ the same midrange, wide dispersion tweeter and complex crossover configuration which includes phase correction circuitry to compensate for unit spacing.
The TLS 50 II however, also boasts a super-tweeter which further extends the high frequency performance well beyond audibility and as such compliments the plane source propagation of the line, down to sub-sonic frequencies.
