SoundBuckets by Crookwood

The SoundBucket is a compact, portable, quality speaker, capable of some serious sounds. Using the latest Bluetooth technology and old school analog design, you can stream quality stereo music, and remote control them from your phone, tablet or PC.

Despite it’s compact size, the SoundBucket is a real Hi-Fi speaker, with two quality drivers - a dedicated small tweeter and huge 4” woofer. This classic arrangement means the SoundBuckets sound “right” across the whole musical spectrum, not tinny, not boomy, not lifeless or aggressive, just beautifully accurate. Inside the box are two powerful 30W power amplifiers, and some equally powerful rechargeable batteries. This power is used to provide a stunning bass response and the ability to play music truly loud, with power and importance. It’s like having a big Hi-Fi you can just pick up and move around with you.

We’ve made the SoundBucket really easy to use, and really easy to connect to all your music players.

It’s all controlled by a single button with a multicoloured LED and you can use the normal controls on your phone etc to do the rest. No complicated double volume controls or weird features you’ll never need!

• If you’ve got music on a phone, tablet, or computer you can just connect wirelessly via Bluetooth. Simple, secure and with a great range it’s so easy to do.
• It works with all streaming services – Spotify®, Deezer®, Pandora®, Tidal® and even Apple Music®. Just stream to Bluetooth and the SoundBucket does the rest.

• Got aptX®? This is a superior way to move audio across Bluetooth. We’ve invested in supporting this great standard (we’ve known the aptX guys since the 80’s and know the product well from hi-end pro audio) to get the best out of Bluetooth. If your device has aptX, the SoundBucket will automatically connect to it without you having to do a thing.
• Don’t have Bluetooth? No problems, just use the cable we supply with every SoundBucket to connect it to your device.
• Want stereo? We used the latest Bluetooth system so you can wirelessly link up two SoundBuckets for great stereo with accurate imaging and impact. We also support wired stereo, using our supplied cable.
• Pono Player, or Hi Res? Just use our supplied cable. Our aux input jack connects directly to the analogue speaker amplifiers inside via our precision custom analogue circuits; no digital re-sampling, manipulation or compression, just pure sound, the perfect way to enjoy your Hi-res audio experience.
• Want it even louder? Just use the external DC input with our optional external power supply to boost the volume to impressively loud levels.
