B&W CM1 concept90

Commentary

Concept 90 series book shell type speaker system.

The concept 90 series has been designed in the relationship with Kenneth Grange who is in charge of Pentagram Design Laboratory.
For the concept90 series, only the model number was written in the catalog at that time, but since CM1 and CM2 were sold with the same model number, it is written as concept90 at the end of the model number.

A 12.6 cm cone type woofer is installed in the low range.
This unit uses a Kevlar cone.

A 2.6 cm metal dome type tweeter is installed in the high range.

The network has a built-in protection mechanism, and B & W's unique APOC (Audio-Powered Overload Circuit) prevents thermal damage to the unit.

The enclosure is sealed and B & W's matrix enclosure is used for the internal structure.
This system adopts a unique three dimensional structure in which the interior is arranged in a lattice shape, and has high rigidity, thereby eliminating the harmful resonance of the cabinet which makes sound muddy.

There are 3 color variations : white, black, and gray (matte NEXTEL).

A stand corresponding to the leg is attached.

There was a CM column sub-bus module as an option sold separately.
The CM column is the same as the lower woofer of CM2concept90. By adding the CM column, the configuration is equivalent to that of CM2.
