“No dinner party is complete without music, speakers provide an excellent conversation point as well as great sound.”

“Deeptime speakers seem like they’re from another planet! These speakers are anything but ordinary.”

“The Czech company Deeptime has found a recipe for the perfect sound and designed speakers you don’t want to hide in a corner.“

“Through a holistic design process, they have integrated the most efficient drivers into optimized shapes for the rich sound.”

“There are no straight lines in nature.

Therefore, speakers must have no straight lines.”

“Is this the world’s first speaker system made from sand?

Of coarse, it is.”

TRIPLE PORTED SUBWOOFER FOR DEEP LOWS

Receive deep satisfaction from the rumbling lows when listening to music, playing games and watching movies.

PREMIUM CABLES

Twisted cable pair made from Pure Oxygen-Free Copper improves noise immunity and reduces antenna effect.

VOLUME & BASS CONTROLS

The Thunderstone’s controls are intuitive and eye-catching. The external ring adjusts the bass volume, while the internal ring controls the overall volume, so you can optimize your listening experience. Both rings are equipped with neodymium magnets and ball bearings, for a durable design meant to perform for decades.

THE BASS TRINITY

The trilateral symmetry plays a crucial part in the Thunderstone design. The form is armed with three acoustically optimized helical bass ports reinforcing the structure and minimizing its resonance. With three bass ports, the Thunderstone produces deep, clear frequencies, right down to 40 Hz.

HIGH-END ELECTRONICS

Thunderstone is powered by a set of bespoke DEEPTIME circuit boards. The control board features a Bluetooth chipset that runs aptX & AAC audio codecs. Its beating heart is a powerful, D-class integrated amplifier with ultra-low noise levels. All electronic modules are manufactured by an award-winning European company.

AMBIENT LIGHTS

The subtle amber LED light found on the Thunderstone’s bass port calls to mind deep-sea, bioluminescent creatures. It gently brightens as the volume increases and clearly indicates when your system is on standby. Once switched on, the power light will appear on so you know your system is working. When connected to Bluetooth gentle flashing indicates your device is paired and the system is ready to play.
