1.A comprehensive, all-around speaker with a full range of high, mid, low, and ultra-low frequencies, featuring ultra-low frequencies as low as 22Hz, or even lower. The low frequencies below 22Hz depend on the acoustic treatment of the user’s room and can theoretically go down to 18Hz, providing extremely low bass (infrasonic waves) and powerful high frequencies (ultrasonics).

2.Point Source Design: This speaker stands over 2.1 meters tall and includes up to 8 drivers in a single speaker. Through clever structural design and non-traditional acoustic tuning technology (a world-first), it achieves highly accurate stereo imaging and phase alignment.

3.Suitable for transistor amplifiers with power ratings from 500W to 1000W, and also compatible with separate amplifiers (multi-amplifier systems), featuring an external crossover and adjustable distributor design.

4.The reversed tweeter design enhances the sense of airiness in the high frequencies.

5.The image below shows the spherical dome Beryllium film tweeter.

6.There are six adjustable vent designs for processing complex low frequencies. The image below shows the 6.5-inch mid-bass driver, which integrates seamlessly with the 13.5-inch subwoofer in the 100-200Hz crossover range.

7.Two 13.5-inch subwoofers can produce ultra-low frequencies as low as 18Hz.

8.Genuine piano lacquer finish (not PU or other fake piano lacquer finishes). There are two types of piano lacquer: genuine and fake.

9.Removable caster system for easy repositioning, with 100mm diameter wheels to manually adjust the speaker's level, and a built-in level indicator.

10.The ideal listening position is 5.0-5.5 meters away, with a height of 1.4 meters. The image below shows a simulated usage scenario.
