Regarding this issue, I will give you a simple analysis today. Let’s share it together.

　　A3

　　A3 is a large three-way line array speaker. It consists of two 15" low-frequency drivers, two 6.5" tapered drivers loaded with multipath waveguides, and four 0.65" exit compression drivers loaded with dual-port waveguides.

　　The core of A3, just like its predecessor, A1, is a 6.5" neodymium magnetic cone driver composed of M6 mid-frequency drivers loaded with international patented multipath waveguides. This technology not only improves the sensitivity by 10 decibels, but the M6 channel also eliminates harmonics, so The distortion level when the maximum sound pressure level exceeds 10 decibels is lower than that of ordinary direct radiators. M6 also has a wide horizontal beam width and a high cut-off frequency of 4kHz, so a small diaphragm light compression driver can be used to improve sensitivity and detail. Aura Audio The combination of D80DSP or D100DSP power supply controller and D80 or D100 non-processing amplifier can drive up to twelve A3s.
