Below is my text from 6/1/2013 "New SDR CommRadio CR-1", page 28:
"I've been playing around with various audio solutions and have found what, for me at this time, is a great answer to all of my challenges. Best Buy closed their music department rooms in those stores which had them, now turning them into Samsung Experience rooms (to compete with the Apple stores). They had a fantastic sale during the last few days and I picked up several Roland CM-30 Cube monitors. They have a 6" diameter bass / midrange speaker and a smaller treble speaker, 30 W amplifier, numerous inputs and separate volume and tone controls for each channel. The thing is basically a mixer panel and a powered music/audiophile monitor in one package. I have all of my transceivers and both SW receivers hooked into it, and it has a separately controlled headphone out jack. It also makes a nice stand for the CR-1! It looks a bit disproportionate as a stand-alone setup, but when racked and stacked with my other stuff, fits just fine. Just my solution to my challenges."
In the year plus that I've been using this setup I've been pleased and have appreciated the flexibility the built-in mixer panel gives you with the various inputs. I did use two for a short while, but didn't find the second speaker to be of value since the source is monophonic. I just checked prices and the CM-30 seems to be selling at ~$219. from various sources. I hope this is of some help.
