Makes a versatile mini PA too!

The Roland CM-30 Cube Monitor delivers 30W of audio punch through a rugged, high-quality 6.5" coaxial 2-way speaker with stereo preamp. The CM-30 is designed for home-studio and wide-ranging monitoring applications, but it can be used for live monitoring onstage as well.

The Roland CM-30 monitor speaker offers more than enough inputs to simultaneously connect a microphone, a keyboard, a rhythm machine, and a CD player, or to function as a mini-PA rig. It's equipped with 3 input channels, with one XLR mic/line input and 2 additional AUX RCA and stereo mini-phone inputs, making a total of 5 simultaneous inputs possible (4 stereo and one mono input). The Stereo Link function allows 2 CM-30s to be linked for true stereo output, which enables a total of 10 inputs.

Sound can be further refined with the Roland speaker's onboard 2-band equalizer. As with all other controls, the EQ knobs are conveniently located on the front panel for quick access.

The Roland CM-30 can be easily and safely toted from location to location thanks to its built-in handle grip, protective metal grille cover, and cabinet corner protectors. Other handy features include a stereo headphone jack and mic stand adapter.

  • 6.5" coaxial, 2-way speaker with stereo preamp
  • 30W output
  • 3 input channels, with one XLR input for mic/line and 2 additional aux inputs
  • Stereo Link function for stereo connection between 2 units, for a total of up to 8 stereo inputs and 2 mono mic/line inputs

Perhaps a good practice monitor, but nothing more.

Comments about Roland CM-30 Cube Monitor:

Was disappointed at the small sound from this monitor. I am not new to monitors for stage pianos and was surprised at how puny this was, especially after reading other reviews. After changing cords and working with all the settings, nothing improved. Perhaps a defective unit, but not worth sending it back - it would cost 20% of the value of the speaker to send back. For the price there are better options out there.

Roland knows what keyboard players need in an amp

Comments about Roland CM-30 Cube Monitor:

I bought 2 of these to use as a stereo setup made easy by the link feature. My keyboards all have stereo outputs and this amp (and few others) have stereo inputs. Sound is very clean - like listening through near field monitors. Bass is quite good for the speaker size. 30 amps is good for solo/acoustic style playing. Can't keep up when I'm jamming with guitar player who has a 300 watt fender, but that's not what they are meant for. If they came in 60/100 watt version, I'd trade up as long is they were still easily transportable.
