The TIDAL Akira

The TIDAL Akira

Tiralit™ Ultra Cabinet

The cabinet of the TIDAL Akira is made out of TIDAL’s proprietary cabinet material, TIRALIT™. This cabinet material combines the rigidity of hard materials such as metal with the resonance absorbing behavior of softer materials such as wooden materials like MDF.

Diamond Tweeter

The TIDAL Akira uses the same diamond tweeter technology as the big La Assoluta, it is a 1-carat pure diamond diaphragm tweeter with 30mm diameter (1.2″). Not only is it the biggest diamond tweeter in the world, TIDAL was also the very first company to use a 30mm diamond tweeter. 

Diamond Midrange Woofer

TIDAL’s exclusive 80 mm midrange woofer is the result of the Accuton TIDAL cooperation and is to be found only in TIDAL speakers, Akira and La Assoluta. The diaphragm itself is made out of pure diamond. 

Aside of the unique motor- and basket design, its unique 80 mm diamond diaphragm has the perfect diameter to be small enough to have an amazing off-axis dispersion and low moving mass for excellent impulse response

BCS Woofer

Another specialty only found in this speaker is the BCS woofer of the TIDAL Akira. The drivers were designed to play within the bass chamber with its big inner volume to play extremely deep, fast, and without compression, at the lowest and highest reproduction levels.

BCS Radiators

The TIDAL Akira is designed to play ultra-precisely, even at the deepest frequencies. Each Akira is equipped at the backside with five long excursion passive radiators to support the front-firing woofers with a very deep and low distortion reproduction of bass frequencies without any movement noise.

Passive Crossover

Mounted in a hermetically shielded chamber are pure copper foil capacitors, coils of the same caliber, and silver-carbon resistors – only the finest components with proven long-time stability are used for our crossovers.

Silver Terminal

The Akira includes Tidal’s pure silver binding posts. The complex construction is of a fiber-reinforced polymeric material that avoids any inductive electromagnetic field.
