Product Description


K-Array KRM33

The KRM33 or “the cheese box” as it has been affectionately nicknamed, is an ultra-compact and low-profile powered wedge
speaker with a controlled horizontal pattern and has an extended frequency response. It is made up of three 3.15” cone
drivers and one 6” passive radiator. This combination guarantees a controlled and linear emission on a really wide range, with
a bass enhancement mode that can go from 70Hz to 18KHz.

The KRM33 is equipped with a two channel amplifier and a DSP that can be used to adjust the EQ directly inside the box.
An USB direct connection guarantees an easy plug & play connection. The DSP also offers the possibility of changing the
horizontal pattern of the single speaker and its bass response, two buttons located at the back of the box are used to quickly
change these settings without the need of a computer.

The controlled horizontal dispersion gives the possibility of creating horizontal arrays which increase the SPL and the coverage
while maintaining a high and constant signal-before-feedback within all the cluster’s beams.

The stainless steel chassis is a sturdy and durable box solution which is also remarkably short in height. Thanks to this
feature the KRM33 can be easily and discreetly integrated in scenography designs, broadcast studios as well as under-balcony
speakers in theaters.

All the components of the Redline KRM33 are designed by the K-array R&D department and made in Italy under the K-array
quality control system.
