ACOUSTIC ENERGY AE2

Commentary

A speaker system that thoroughly pursues its attractiveness as a monitor.

AE2 has received minor changes by engineer Clive Gibson.
At this time, the network was improved and the punching metal of the tweeter protection was removed.

Two 9 cm cone type woofers are installed in the lower range.

A 2.5 cm dome type tweeter is installed in the high range.
The unit features a copper-plated aluminum voice coil, heat-sealed to a magnesium alloy dome, and a magnetic fluid filled between the magnet and voice coil to provide effective damping and cooling for sharp playback sound.

Silver solder is used for the network part.

The enclosure is made of 22 mm thick fiberboard and has a dead internal structure that does not cause standing wave interference inside the cabinet.
There are multiple finishes and there are 3 variations of black texture, rose wood and piano black.

There was a speaker stand sold separately.
This stand is a heavy weight design with a ball-sized steel ball filled in the hollow of the column.
