Selectable output modes optimize battery life for different performance needs. Review: A really good quality amp for busking and small venues. - The amp is reasonably light and ideal for busking and small venues. 50w of power via the power cable or via 8 rechargeable batteries. Quite a long performance life using the batteries and there are 3 settings to enable battery saving. The best thing is not having to use a built in rechargeable battery (which always end up giving you problems) but simply using 8 ordinary AA rechargeable batteries. Sound quality is formidable with EQ settings on the two main XLR/Jack plug inputs and reverb. The instrument input has a selection of good effects for guitar, including chorus which is really nice. Very pleased with this item so far. it can also be mounted on a speaker stand via the slot on one end of the cabinet. Way, way better than the cheaper alternatives. Review: Amazing powerful Sound, Lightweight & excellent Endurance - Amazing unit for use as a guitar playing vocalist. The sound is both rich and huge. Battery life seems to be very acceptable- used for about 4 hours already on mid power level and still more than half life left in rechargeable batteries. I would recommend that a spare battery case is purchased so that if being used for a gig, it would be a simple and quick operation to swap over battery packs ( two finger screws) rather than fiddling about trying to insert new cells in the existing pack. I bought a couple of spare packs online from a music store. The only complaint I have is that when using an external music source (backing tracks) such as iPod etc using the dedicated input, the sound from this input is rather thin and tinny ( no EQ available). I am currently exploring the use of a separate battery powered EQ unit to solve this. For info, the microphone used for my testing was Shure SM58 with soprano vocalist. Guitars used have all been acoustic electric and include Taylor 814ce, Tanglewood TW4 KOA and Walden T550CE. All sound fantastic with crisp highs, warm mid range and rich powerful bass. So far so good. More to follow as usage experiences build. Please note that the supplied photos are taken of the unit housed within the optional case which is subject to separate purchase. ## Features - Innovative new Roland technology provides 50 watts of stereo power from eight AA-size batteries - Selectable output power modes to optimize battery life for different performing situations (Max: 50 W/5 hours; Normal: 25 W/10 hours; Eco: 10 W/20 hours*) - Portable, lightweight design (7.4 kg/16 lb. 5 oz.) with durable ABS injection-molded cabinet, plus a powerful, full-range stereo sound with dual 8-inch woofers and 2-inch tweeters - Four independent channels support a wide range of mics, instruments, and audio devices, with two XLR inputs for dual vocal performances - COSM tones for electric guitar, including Clean, Crunch, and Lead; preamp for acoustic guitar provides clean, natural sound - Angled back for use as a stage monitor; mounting hole for use with optional ST-A95 Speaker Stand - Stereo Line Out jacks for connecting to an external sound system when used as a stage monitor - Stereo Link jacks to connect a second CUBE Street EX for broader sound coverage - Easy recording into your iPhone/iPad via i-CUBE Link and free CUBE JAM app - Optional CB-CS2 Carrying Case made with water-repellent material ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JMU1RAG | | Amplifier Type | Solid State | | Audio Output Mode | Stereo | | Best Sellers Rank | 17,568 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 30 in PA Power-Amplifiers | | Box Contents | Owner's Manual | | Brand | BOSS | | Brand Name | BOSS | | Colour | Black | | Compatible Devices | Guitar, all | | Compatible devices | Guitar, all | | Connector Type | XLR, 6.35mm Jack | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 383 Reviews | | Enclosure Material | Battery | | Global Trade Identification Number | 00632709972656, 00761294505625 | | Item Dimensions D x W x H | 60D x 41.1W x 33.6H centimetres | | Item Highlight | Clear, Dynamic Sound | Ideal for Outdoor Performances | Supports Mics, Instruments & Audio Devices | | Item Type Name | Amplifier | | Item Weight | 9.1 Kilograms | | Manufacturer | Roland | | Manufacturer Part Number | CUBE-ST-EX | | Material | Battery | | Model Name | Ampli Cube Street Ex Roland | | Model Number | CUBE-ST-EX | | Number of Bands | 2 | | Number of Items | 1 | | Output Channel Quantity | 4 | | Output Wattage | 50 Watts | | Output wattage | 50 Watts | | Power Source | Battery Powered | | Product Warranty | 1 year manufacturer. | | Product dimensions | 60D x 41.1W x 33.6H centimetres | | Speaker Size | 8 Inches | | UPC | 761294503089 632709972656 761294505625 | ## Product Details - **Brand:** BOSS - **Colour:** Black - **Compatible devices:** Guitar, all - **Material:** Battery - **Output wattage:** 50 Watts ## Images ![Roland CUBE Street EX | Battery-Powered 50W Stereo Amplifier - Image 1](https://m.media-amazon.com/images/I/81bVVgEFxqL.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Questions & Answers **Q: Do backing tracks sound loud with the roland street cube ex?? i busk on the busy streets of london and need something loud!** A: Yes I’ve been using one for 2 1/2 years busking and gigging and never had a problem with getting a good volume **Q: Any good for electric guitar???** A: I use it with an electrified acoustic Ortega guitar and I consider it to be very effective in volume and sound quality for my guitar and vocals. I play traditional folk and my own compositions including protest songs! I heard a Cube being used in Lincoln by a good lead guitarist in the street and it sounded great. It is really the only option for street performance as you can run it on batteries if a mains supply is unavailable. Good settings options and reverb. works well. So it suits me well and sounds good to me with an electric playing lead in the street. Best of luck! **Q: How does a keyboard sound through this amp?** A: Yes it’s very good for keyboards/piano, especially when using the stereo channels, there’s more headroom when on the mains, the battery use is convenient, but you lose a bit of tone and head room running on batteries. Adam **Q: The main reason why i want to connect this to my tv is when where doing karaoke through you tube and can i used this as a cinema speaker** A: Yes--you can have a mic input to the Roland and a Line In input from the TV, as long as the TV has an audio out, which you can connect to 1 or 2 1/4" jacks (depending on whether you want mono or stereo signal from the TV to the Roland. Should work great. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A really good quality amp for busking and small venues. *by J***N on 22 February 2024* The amp is reasonably light and ideal for busking and small venues. 50w of power via the power cable or via 8 rechargeable batteries.

However I am going to be gigging in larger venues so I purchased another of these to join together to give a total output of 100 watts. This is a brilliant amp full of settings I don't use but at least they are onboard. I play acoustic/eclectro guitar, tin whistle and harmonica, I produce my own backing tracks. So I mainly use reverb for voice and other setting on guitar to give it a different sound especially on ballads. Example I will use a slight chorus and delay to give the guitar a beautiful sound. I heard this live at one of the Dubliners concerts some years ago when their sound engineer did it for Jim McCann when he was singing Carrickfergus. Finally Best amp I have ever owned and this Seller is excellent the product arrived factory sealed and very prompt so I highly recommend this Seller. ## Frequently Bought Together - Roland CUBE Street EX 2x8" 50-watt Battery Powered Combo Amp - GEBIBB Bag/Case for Roland Cube Street EX Amplifier,Backpack - EBL AA Rechargeable Batteries,16-Pack Double A Battery (ProCyco 2800mAh) with AA AAA Battery Charger --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/50050409-roland-cube-street-ex-battery-powered-50w-stereo-amplifier](https://www.desertcart.sk/products/50050409-roland-cube-street-ex-battery-powered-50w-stereo-amplifier) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-21*
