The S90i’s highly efficient design yields fast, dynamic, articulate results with accurate timbre. This is a high-end subwoofer solution for customers who desire no-compromise performance, but prefer the aesthetic benefits of custom-installed, hidden loudspeakers. The S90i’s superb performance characteristics include a flat response to 20 Hz with usable in-room energy down to 17 Hz, and outstanding dynamic capability, and accurate timbre reproduction. Three versions are available: S90i (when an exposed grille is needed), S90 basic-port (when you are going to place it behind scrim cloth/acoustic fabric and you do not need a grille, and S90-f/c (when you need to extend the port of the S90 from the attic, crawl space, or an adjacent room).

The Regenerative Transmission Line®

Regenerative Transmission Line® designs yielded the unique combination of high sensitivity, high output, and low distortion with the uniform and extended response we required. The result is extraordinary power and punch combined with a remarkable level of quickness, tunefulness, and realism.

⭐⭐⭐⭐⭐ "Excellent value for money and very efficient charging!" I bought this pack of 2 MagSafe chargers from TNDAJI and I couldn't be more satisfied. I love that it includes USB-C to USB-A adapters. This allows you to use them with both modern and traditional charging cubes, which is a great detail. The magnet adheres perfectly to my iPhone and does not release easily, allowing me to continue using the phone while charging. The blue light ring gives it a modern and elegant touch, in addition to helping to locate the charger easily in the dark without being annoying. The 15W works wonderfully. Charge my AirPods and phone quite fast for a wireless connection, and I haven't noticed excessive heating. For the price of an original one, you get two high-quality chargers with their adapters. Super recommended to have one in the office and another on the bedside table!"
