Say Hello to SPRINT! Reimagining What A Speaker Can Do…

SPRINT 3, the 2-way standmounter inherits the ATALANTE line technologies.

SPRINT proudly inherits the same technology that powers Revival Audio’s ATALANTE line, with a twist that makes it uniquely SPRINT. It features a 28mm RASC soft-dome tweeter and built-in ARID (Anti-Reflection Inner Dome) patented technology. With its specialised back-chamber design, this stylish speaker design is capable of absorbing over 95% of unwanted resonance within any space to elevate your listening experience, whether you’re reminiscing over your vintage vinyls or playing your favourite new playlists of the 21st century.

SPRINT also features the high-end BSC (Basalt Sandwich Construction) 7” woofer, perfectly balancing out rigidity and lightweight design. With superior damping construction, SPRINT promises a rapid yet smooth response with impressively tight bass dynamics.

The ELYTRON front baffle is an original Revival Audio creation; a stylish speaker design developed through hundreds of hours of painstaking simulation. Such listening precision has never been seen before at its level, and won’t be seen again soon from any other manufacturer, unless they copy SPRINT. But that’s ok, because that’s our goal: To create new trends and technology in the speaker industry, with sound precision that must be heard to be believed.

Directivity Control, Diffraction Optimization

ELYTRON is the front baffle of SPRINT, with fabric grills attached from behind.  The magnetic baffle can be either attached or removed  from the cabinet with ease.

The asymmetric shape with specially set curvy angles enhances the high-frequency’s directivity as a waveguide (refer to the simulation below).

Also, it optimises the mid to low frequency performance by reducing the diffraction impact from the MDF cabinet.  ELYTRON is made of high-rigidity compound materials to assure the stability of its performance under any listening scenarios.

With ELYTRON, the sound image is more precise and balanced, while minimising the impact from different listening environments.

RASC 28mm Soft-Dome Tweeter

Detailed Restitution, Beyond Expectations

RASC Tweeter is the iconic driver of Revival Audio.  It is a 28mm soft-dome tweeter, coated with our own secret recipe, and built-in Revival Audio ARID+ (Anti Reflection Inner Dome) patented technology, to absorb 95+% of resonance in the chamber.

The ASYMMETRICAL SUSPENSION provides a more linear resonance-free guiding of the dome, to have a better dispersion, as waves travel freely to the side.

The oversize FERRITE MAGNET SYSTEM offers a high magnet force and A efficiency of 91dB can be comfortably reached.

Through BCD (BACK CHAMBER DAMPING) RESONANCE-FREE DESIGN, the structured rigid back cover with asymmetric rims is precisely simulated for the purpose of resonance absorption. It helps to get a low resonance frequency of 560 Hz.

BSC 7” woofer

First in Hi-End, Feel The Dynamics And Precise Punches!

BSC (Basalt Sandwich Construction) woofer is definitely a Revival Audio unique and iconic (visually too) technology.   Basalt is extracted from lava stone which has never been used in Hi-End audio, with similar characteristics as glass fibre but a better Young modulus.  It is also an eco-sustainable material.

The Sandwich construction consists of 3 layers, a special-defined felt sits inner applied to the back of the Basalt membrane and a specialised polymer glue lies between which results in the best-possible damping.

With BSC woofer, its lightweight and rigidity with excellent damping provide a fast and smooth response with tight bass dynamics.


At Revival Audio we tune the crossover by hand, by placing real components on one tuning board and measuring the results. When done, we listen (a lot) and fine-tune, after that, we check again with measurements that we went in the right direction.

“Measurements define good crossovers, but only craftsmanship and experiences build extraordinary ones”
