The AE309 speaker uses a metal diaphragm for the mid-bass unit and a high-quality rubidium magnet silk dome for the tweeter, providing high transparency, dynamic range, and power handling capability. The metal diaphragm ensures perfect piston motion and helps dissipate heat from the voice coil. There is a sponge plug at the back of the speaker for adjusting the bass level. The speaker can be connected to the amplifier output jack using the traditional wiring method, bi-wiring method, or bi-amp method. The speaker has a high power handling capability, with a frequency response range of 37Hz to 23kHz. The cabinet features a wood veneer finish, a 30mm thick front baffle, and gold-plated bi-wire terminals. The speaker weighs 18kg and has dimensions of 210x920x395mm.
The manual describes the AE309 speaker’s construction, including a metal‑diaphragm mid‑bass unit, a high‑rigidity aluminum‑magnesium alloy diaphragm, and a high‑quality silk‑thread tweeter. All drivers are magnetically shielded and the cabinet features a wooden veneer finish with a sponge plug for bass adjustment.
It explains three wiring methods – traditional single‑pair, dual‑wire for separate high‑ and low‑frequency connections, and dual‑amplifier wiring using two amplifiers. Installation steps, screw tightening order, and placement guidance (forming an equilateral triangle with the listener) are also covered, along with detailed technical parameters. This manual is written in Chinese.
