The design specifications for the Columa 900 were very clear: a great-looking loudspeaker set that seamlessly blends Teufel’s renowned hi-fi sound quality into the living environment. Visual compatibility with flatscreen TVs was also a priority.
Next to the tried and proven column layout of the loudspeakers, the low depth of the column cabinets is a crucial design factor – with a modest depth of only 8.3 cm, these columns can be easily integrated into most environments. Naturally, Teufel made sure that such a sleek exterior would in no way compromise the Columa 900’s excellent acoustics.

The centre column speaker is designed as an elaborate 2.5-way system. Of the four mid-range drivers, the two bottom ones have a lower treble cut-off frequency than the upper two, which reach all the way up to the dome tweeter’s cut-off point.

This has several advantages: less frequency drop-outs thanks to the elimination of clashing frequency delays between the cabinet and the listener; high load capacity; and a linear frequency range right down to 100 Hz. The unusually low bass crossover frequency of the two bottom drivers adds extra warmth and punch, which will be much appreciated by music lovers who are otherwise sceptical of column speaker designs. Unlike most column speakers, the CL 90 FR is in fact a fully fledged hi-fi speaker – in the guise of a sleek designer column.

The D’Apollito array of tweeter and mid-range drivers in the FR speakers is mirrored in the CL 90 C centre speaker. The result is a homogeneous sound field that can only be achieved through identical driver combinations. The slim housing design of the centre speaker integrates seamlessly with a flatscreen TV. The speaker can easily be wall-mounted or attached to the accompanying table mount.

The visual profile of the centre and column speakers is also reflected by the matching Columa subwoofer. The CL 900 SW has a surprisingly shallow cabinet with gently rounded corners and a subtly convex oval contour. The friendly, almost chubby design of the subwoofer is in stark contrast to the sonic punch it packs – there is no compromise in the bass being delivered here.

As a system, the Columa 900 is the perfect surround speaker set for music lovers who want their loudspeakers to blend in seamlessly with a modern living environment.

CL 90 FR

The CL 90 FR is designed as an elaborate 2.5-way system. Of the elegant column’s four vertically spaced mid-range drivers, the bottom two have a lower treble cut-off frequency than the top two.

This has several advantages: less frequency drop-outs thanks to the elimination of clashing frequency delays between the cabinet and the listener; high load capacity; and a linear frequency range right down to 100 Hz. The unusually low bass crossover frequency of the two bottom drivers adds the kind of warmth and punch that would otherwise be expected from a conventional hi-fi speaker design.

The frequency range of the two top mid-range drivers reaches right up to the cut-off frequency of the 25 mm cloth dome tweeter. As specified by the D’Apollito design, the tweeter is positioned exactly halfway between the two mid-range drivers.

CL 90 C

Naturally, the Columa 900’s centre speaker is equipped with the same drivers as the CL 90 FR column speakers. This is the only way to guarantee the system’s overall aural homogeneity.

Again, the 25 mm cloth dome tweeter is positioned exactly halfway between the two mid-range drivers, ensuring the audio action extends well beyond the listening sweet spot in the centre of the room.

The slim housing is designed to integrate seamlessly with a flatscreen TV. The centre speaker can be attached to the wall using the integrated mount, or it can be attached to the table mount that ships with the system.

CL 900 SW

The CL 900 SW transports the visual profile of the Columa satellite speakers into the nether regions of the subwoofer.

This remarkably slim subwoofer with its gently rounded corners and a slightly oval contour surprises with a very balanced bass response. It features two vertically positioned 200 mm drivers that are powered by a 250 watt RMS Class D amplifier.

Packing quite a punch thanks to an unexpectedly large cabinet volume of 45 litres, the CL 900 SW can easily provide sufficient bottom end for rooms sized up to 50 m².
