At last, a review of a Tidal speaker! Stereophile has reviewed the Akira:
A few points that stood out to me:
The limited bass extension appears reasonable to me. Still the speaker will need some distance from the walls. Also reasonable for that kind of product. This may not be a LOUD speaker, but it might have very good coherence.
These cabinets are just plain incredible IMO! Like the picture of the crossover being installed. 8O I need this!

A few points that stood out to me:
- The ports are tuned to 42Hz. In-room response drops significantly below 40Hz. This appears to be a flat tuning. Average sensivity, quite low considering cabinet size, impedance and the bass extension.
- Appears to be an LR2 topology, with a "2/3" arrangement for the woofers, with the cut-off frequency declining by height. Tidal appears to be very concerned about vertical power response. Crossover frequencies are 250Hz and 2200Hz.
- The off-axis measurements look very good, including the vertical one.
- No LCR-circuit damping the upper spike of the port effects. Don't see a hump, though. Near field measurements would have been nice.
- Allegedly 80lb pounds of gloss-lacquer. 44lb crossover. Didn't find the weight of the cabinet feet again, but same ball-park, weightwise. Crazy, I like that!
- Both impedance and acoustics measurements indicate that they didn't deal with the midrange pipe resonance at 1,2kHz that could also be seen with its -724-brother. Appears to be audible too. Small downer IMHO.
- Tweeter was fried by accident. Not too surprised given the LR2 @ 2.2kHz.
