This portable PA adapts to your needs

When we recommend portable PA systems at Sweetwater, we like to give you as much flexibility as possible to handle any performance situation. The CUBE Street EX gives you everything you need to get a great sound out of your electric guitar, acoustic-electric, or vocal microphone. A handy built-in tuner helps you sound your best, and COSM amp and instrument modeling gives you solid tones for any style of music. You can fine-tune your sound with a 3-band EQ and reverb on each channel. And with the stereo link outputs, you can connect a second CUBE Street EX for even more sound coverage.

Great sound anywhere

Roland CUBE amps are famous for performance that exceeds their physical size, and the CUBE Street EX is no exception. With two 8" speakers for powerful lows and rich mids, plus two 2" speakers for crystal-clear highs, this amp sounds incredible. It's capable of high-volume output that defies its physical dimensions, which is why it's just as suitable as a PA as it is a guitar or vocal amplifier. Best of all, it can run for up to 20 hours on just eight AA alkaline batteries.

i-CUBE LINK connects with your iOS devices

Roland's innovative i-CUBE LINK interface gives you easy, quick connectivity with your iPhone, iPad, or iPod touch. You get two-way communication with your iOS devices, so you can jam with music tracks and send studio-grade guitar tones directly to your favorite recording apps. The i-CUBE LINK jack may also be used as a regular stereo input, letting you plug in virtually any music player or audio device and play it through your CUBE Street EX. The companion CUBE JAM app (available free from the App Store) turns your iOS device into a versatile jamming, recording, and learning station.

Roland CUBE Street EX Combo Amp/Portable PA Features:
  • 50-watt portable PA speaker with 2 x 8" LF drivers and 2 x 2" HF drivers
  • Perfect for amplifying electric guitars, acoustic-electric guitars, vocals, keyboards, and drum machines

Awesome Amp

Received my new amp today. My wife and I did a practice session on it before I wrote this review. It is truly awesome. I first played my 46 year old classical through it. It sounded great. I then played my new Ibanez AS153 through it; again awesome. Had my wife sing some jazz songs through it while I played for her. Yes, it is in my house but if I turned it up more then halfway it would blow us out. The sounds are absolutely clean and quiet unless you choose to add something in. Anyone looking to buy a good amp for busking and/or small to medium venues this is really good. BE AWARE, even though the description of this amp does not say; it DOES come with a power supply. No need to buy a separate supply. Again, my friend Chris Kress at Sweetwater did a stellar job. He has kept me informed every step of the way for the products I have bought so far.

execlent equipment

I bought two Roland Cube Street EX amplifiers for my kn7000 stereo keyboard, and they sounds better than I expected. They are great little amps with plenty of power. I also bought two Roland BA-330 PA amps that I link together for my PA system. The pa system has great coverage s well. I love my Roland products. The people at Sweetwater were very friendly and helpful. If you have any hesitation when considering any one of these fine products don't. I am well satisfied.

I'm using the Cube in Liberia, Africa

Wow, I am impressed! I highly recommend the Cube Street Ex to anyone looking for high quality portable sound. I am not an entry level musician. I have studied music and sound engineering. I say this because I am very picky about my sound. I am a missionary to Liberia, Africa. Where we live, there is no electricity. The cube has enabled me to bring high quality dependable sound into the middle of Liberia's rainforest. I strap the Cube to my dirt bike using bungee cords, travel down some of the roughest roads in the world until they end, then carry it deep into the rainforest. It is very dependable. I highly recommend the Cube to everyone!

I needed a battery powered amp for my sons outdoor wedding, I saw this amp on my first search, and watched the product video. Pretty cool package, so I bought one. I was so impressed I ordered another because they can be stereo linked. Put them on Tri-pod speaker stands and they really sound good. With 3 power settings they can be used in a number of settings. Flat out the best battery powered amp!

Cube Street Ex GREAT

I didn't know what to expect, although I loved reading the Liberia review :-))) And I spoke to a salesman at Sweetwater who owns the original Micro Cube and now this item ( as I do too ) :-) I LOVE to play in a local Park and need a Battery Amp to do so! Being used to the 3 watts of the Micro Cube for 6 years, and pushing it to the limit, I was hopeful........and now a 'believer' !!! Even at the 10 watt Power Setting, it blows away my Micro Cube as the Dual 8"s and dual Tweeters are soooo much more .....:-))))) At 50 watts OMG ! Plus the 3 band eq on 2 channels :-))) The Reverb is very Clean and Nice and the Delay with it is GREAT feature. I'm running it on the 'clean' amp model as I use Native Guitar Rig from my Netbook.....but without my Netbook I could survive with the built in amp models and the reverb and delay! The 24 mo no interest Payout is what made this affordable for me! ($25/mo min) PS Even on AC, I discovered that the Output Power is in Effect! So make sure you turn it up to "Max" when using it on AC, as at 1st, I was wondering why the 1st channel was sounding under powered! PPS A TTRS male mini to TTRS male mini cable is included for an Iphone hookup to a separate channel which I tried and works great!
