OVERVIEW

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.

FEATURES
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
Metal grille cover, corner protectors, and handle grip for easy transport

So far I've been very happy with this after about 7 months. I primarily bought it to use with my old POD 2.0 and Tech 21 guitar amp modelers at home. I wasn't looking for high volume - although it can get loud enough to tick off the neighbors for sure - but I wouldn't use it for a full band rehearsal. I was never happy running the modelers through a normal guitar amp, the cabinet modeling doesn't work well with the limited frequency response of a guitar amp speaker. This Cube monitor is a full range speaker, and I can say my modelers sound the best I've ever heard them. Super easy to hook up a CD player or MP3 player and play along to backing tracks. Small size doesn't clutter up the room if you have limited space. I'm thinking of getting another one to hook up in stereo. I can also use it as a monitor when recording tracks onto my computer. If you use guitar amp modelers and want something to amplify them faithfully without coloring your sound, at quiet to moderately loud volumes, and want to minimize gear space, this is a great choice.
For a small amp/monitor it's got about every kind of input I can think of, plus headphone capability. 30 watts is louder than I thought it would be when it's turned up. Surprising amount of bass reproduction for such a small speaker.
Seems very solidly built. Front speaker mesh is metal, built in handle is very sturdy. Controls have a good feel to them, input jacks seem pretty good. It's fairly heavy for the size. I wouldn't want to drop it because I wouldn't really want to drop anything, but it feels like a high quality piece of gear. I think it sounds great. We've used it as a PA for a birthday party in a decent sized hall playing music (not enough to blow the roof off but plenty loud enough for the kids to have a good time. It's a birthday party, not a nightclub!). I use it playing guitar through my POD and Tech 21 amp modelers (more on this below).
For what it is I don't know what else I would want from it. I bought mine used so saved some money there, but I think the price is fair. It's solidly built and sounds very good, with a good feature set. Maybe if it had onboard reverb, but not a big deal.

Not what it used to be

My friend has a CM-30 from 2005. It is MUCH louder than the one I just bought. Also he paid about half the price.

Comments about Roland CM-30 Cube Monitor:

I've owned it for about 4 months. I perform for various size crowds 2-3 time a week. It is great for small rooms with crowds of 20-40 people. Great coverage an easy to use and transport. For larger crowds I use a different front of house and use this as a personal monitor. It cuts through the room noise and gives me good monitoring. For those uses, it's perfect for me.

      Comments about Roland CM-30 Cube Monitor:

      I'm a one girl band and the Roland CM-30 was just the ticket for me in my smaller venues..I use it as a pa and with a 4 ch mixer, my guitar/vocals/mini disc background tracks come thru beautifully and no one can believe that ALL that sound is coming thru something so small. One night my Bose L1 system wouldn't function and I had no choice but to grab the CM-30 from the van...There I was in a room of 80 people dancing and having a great time, and no one even noticed that I was performing thru the 30-watt cube. I was so impressed that I have since bought a 2nd cube and now use the two as my main set up, only using the Bose in rooms of 200 or more. I have also purchased a small powered subwoofer and when I try it out with the cubes, I'm hoping I will never have to cart around a heavier system..CANNOT say ENOUGH wonderful things about the Roland CM-30...Best musical purchase I've ever made!!! I am in FL and play for retirement golf communities. I play out 4-5 times a week, and some times do 3 gigs in one day...WHAT a difference this has made on my back. Thank You ROLAND!!!

      Comments about Roland CM-30 Cube Monitor:

      First off if you want loud buy a big PA system.
      I have used this with acoustic guitar and vocal mic at small dinner gigs and acoustic jams at fairly loud partys. It will not blow the room away admit. But it puts you above acoustic levels crystal clean and clear. I use a little Behringer mixer that has effects if I want effects. The 4 channel one fits on the top of the 30 nicely like it was made for it. But mostly for simplicity for dinner gigs I have just used it dry. There is nothing wrong with singing through it. I used it as a monitor in front of my larger PA once when I did sound for an open mic. I sat it on the floor and tilted it back in front of the main mic. Worked just fine. Some players said the monitor was a little too hot. I have had every roland battery amp and others. They are all gone. This one is a keeper for the money.

        Comments about Roland CM-30 Cube Monitor:

        I initially got this for a keyboard monitor. I liked the fact that it has multiple channels with volume controls for each. I hooked up my keys and drum machine, expecting it to distort on the low registers but....WHOA!! 
        How does it sound so full with speakers so small!?
        I then realized that it could be used as a stage monitor, and recognized its usefulness in a small stage setting. Got a second unit, and the band's totally stoked that we don't have to lug around cumbersome and heavy floor monitors around any more!

        CM-30 Cube Monitor

        By Roger David

        from Central Illinois

        Comments about Roland CM-30 Cube Monitor:

        We've had this now for a little more than 2 weeks. Used it as the single main speaker (with no monitor) for a worship service at a nursing home. Hooked to it a Peavey mixer; and to the mixer we connected a guitar and two Shure Beta microphones. The room was like two average-sized living rooms put together. Using sound equipment helps some residents hear better--and the guitar sounds better when amplified. The Cube was set at 75-80% of full volume; the mixer was set far below maximums. The supervising staff member said it was the best sound combination we've had (she's been with us for a couple of years and heard us with our Kustom 12-inch monitor (hooked to our mixer), an old Rouge Roller PA and a Peavey Messenger system). I agree with her assessment. When leading the singing, my wife and I could hear ourselves from behind the single Cube monitor when used as the main speaker. Without changing any settings, the voice quality for speaking was top notch as well. We may buy one or two more cubes for use in small to mid-sized rooms--two chained together for true stereo mains and the third as a monitor. The Cube is a good guitar amp in small to mid-sized rooms. Easy portability. More than I expected for 30 watts, especially when compared to our Kustom monitor, which is 100 watt rms.
        I like having three instrument/mike channels and also the stereo/mono capability. Also like the fact that headphone and speaker volumes are independently controlled (each can be heard with or without the other). If controls were on the side, rather than on front or back, the Cube would be more convenient when usage is sometimes as monitor, sometimes as main. Thus far, no issues because the power cord has no ground wire; nevertheless, adding a ground would seem to have minimal effect on price and would perhaps provide added protection.
        Seems well-constructed. At first, I thought there was minor noise in channel but then discovered that TRS 1/4 inch jacks should be used instead of 1/4 inch mono jacks, which are OK for channels 2 and 3.
        Seems to be a good value

        The sound this tiny box puts out is surprising. It puts out rich highs and lows. And there's plenty of connectivity options as well. t can be pretty loud, so it works well as a personal monitor to a degree, like a small jazz club, nothing massive. I hooked it up to my Alesis DM10 eDrums and it sounds exquisite. The cm30 takes very very very little room as well. You'll be amazed at its size. If by chance you do get it and use it right away and here some pinging or distortion, play something thru it for a few hours like an ipod or the likes there of. It will go away, trust me

        I've been looking for a self contained unit that I could use for practice in my living room...something small for guitar or keyboard, vocals, and either drum machine or foot stomp box...with 3 separate inputs, this sounded like a good choice...I was a little sceptacle because of the size...plugged in my guitar: sounded great...plugged in my mic: sounded great...plugged in my Shadow stop box: sounded like it should...so I did some jamming, and I was really pleased...I usually just do solo guitar/vocal gigs these days, and I wanted a small practice amp...this fills the bill....wish it had an effects loop, but I just plug my SM58 into my TC Mic Mechanic, and my guitar into a delay, and I'm all set...the volume and sound quality really belies the size of the CM-30...I really like this and may purchase another for a nice stereo setup, or maybe to monitor my recordings...got a great price too, and it's worth every penny...

        Comments about Roland CM-30 Cube Monitor:

        I was interested in buying this until I played and sang through it. The features for a small product such as this are very good and it felt like a Roland in your hand - sturdy but light. It IS a quality item. It actually sounded stellar with an acoustic electric guitar. For practice, small gigs and such it is NOT adequate for vocals. The sound was good but it was easier to just sing louder - my voice was louder than my voice through it as a pa. It also clips considerably at high volume. I wanted to like it, but feel it is underpowered, overpriced and not loud enough for even coffee shop applications. Ok for guitar but practically useless for live vocals.

            I use this monitor as an acoustic instrument amplifier and to listen to recorded music. For this it works great. I especially like that it is quiet, meaning that it does not have any noticeable humming, clicks or other unwanted sounds it produces. It I also quite portable and seems sturdy. It is not large enough to hear in a loud environment or fill a large room with sound but does a great job for what it is designed for.

              Bought this monitor for cheap about a year ago and am still impressed. I use it for a computer speaker, listening to music, and practicing bass. For music it's solid. No complaints at all. Enough bass out of a small speaker and the mids and highs i had no problem with. I am a beginner bassist and use this for practicing. I play a 5 string bass and it should sound awful, but really doesnt. obviously not enough lows to handle my low b string but not bad at all. Ive also used this for vocals and keys in a live/jam setting and was not disappointed at all. It actually was audible over a drummer playing metal. Its really light and portable. Overall a great product with a great price tag, especially if bought used.

                I got this to use as a multi-instrument practice amp and it really fills the bill. I have used this, at different times, with bass, electric guitar, acoustic guitar, keyboards, and vocals. The low end will start to fuzz a little when playing low bass notes with a compressor, but then there's really little need to add in a compressor for practice purposes.

                A very good value for what it is, a monitor or a practice amp. I could see it serving the purpose in a coffee house situation, but without as much headroom as I would generally want.

                Comments about Roland CM-30 Cube Monitor:

                I really like this little amp. I have to crank this amp to 75% to 80% of volume to get it to sound loud enough to work0 as a little PA. I play guitar, and sing. I use a guitar pedal to get my nice sound, and a TC Helicon "Create" pedal for vocals. The sound is nice and warm, full and correct. So, I have this little tiny amp/PA that makes my overall footprint small and light and flexible. It is a very sturdy little amp. Excellent purchase as far as I am concerned. But, it is really only great because it sends a clean signal that can be colored by all the wonderful pedals that are available. Other folks who want to carry small items and not break the bank or the back, take heed.

                This powered speaker delivers! Lots of killer inputs and outs. Great device for plugging your portable player into. Plenty of bass,mids and highs. I have one which I use as a monitor for listening to play lists from my mp3 player on construction sites and it rocks.I have played my bass through it and it sounds great at lower volumes. It is also great for warming up before a gig in your hotel room. You can plug a couple of guitars,a bass and even a vocal mic into this baby and run through tunes. Sounds amazing with a keyboard. You can plug a sub into the headphone jack for extra bass. In addition you can link two of these little giants together to achieve a stereo image.One is perfect for an extremely portable way to kill the silence of a dull hotel room and make an after show party.Highly recommended.

                  I bought this to play my beatbuddy drum machine through with unaffected signal. Works well, although it does have trouble handling one of the deeper beat settings (bit of speaker rattle), but I think that is too be expected of such a small monitor. Other than that small weakness it works great for what I wanted to do with it.
