Scepter E-503A

Scepter E-Series 3-Way Book Shelf Speaker System with a Scepter Series speaker unit.
The low range is equipped with a W-305A that is a 30cm cone type woofer.

New lightweight cones and foam neoprene rubber edges are used to reduce vibration system weight.
A horn scoker is installed in the middle range.
The new diffusion horn converts sound waves into spherical waves inside the horn, greatly improving the orientation characteristics that were the weaknesses of the horn type.
In addition, a carbide duralumin foil diaphragm is used for the vibration plate, and by actively air braking with the back cavity, the characteristics of transient properties and distortion characteristics are improved.

High range is equipped with TW-1800A, a diffuse horn type tweeter.
The precise horn of aluminum cutting is combined with a proprietary diffusion mechanism to realize a natural sound quality that reduces horn odor. In addition, carbide duralumin foil diaphragm is used for vibration plates, achieving superior stress-distortion characteristics compared to conventional materials.
Level control is installed in the middle and high areas.

The enclosure uses an enclosure of 50L enclosed bookshelf types.
It has a multi-amplifier terminal.
The high range uses a 2.5cm domed unit with aluminum magnesium alloy, which is 25% lighter than before.

You can enjoy a sound field that you can not think of as sound coming from a compact speaker. In addition, the position of the sound is good, each instrument, there is something that gleams in the vivacity of the singer.
