Project Description


The TIDAL Akira. The smaller brother of the La Assoluta, and one of our two ultimate diamond speakers. Built for the absolute approach in a decent sized design. Limited to 10 pairs per year worldwide.

“Very fast, very delicate, very clear on tubular bells, percussion, and wood blocks with just the slightest bit of diamond tweet glare on the very top, but also with simply extraordinary timbre and resolution in the mids. An outstanding floorstander.”

“…Utterly seamless, it was fluid, unforced, expressive and finely nuanced. Intricate and delicate when necessary, it was also capable of remarkable power and sudden dynamic shifts when necessary. Subtle musical shadings and textures were explicit without being exaggerated, and the Akira made a powerful argument for its exotic driver technology.”


A 1.2″ pure diamond diaphragm tweeter, a 5″ pure diamond midrange woofer, pure silver crossover, a cabinet made from TIDAL’s proprietary TIRALIT™ Ultra and much more…
