AERIAL Acoustics Model20T

Commentary

This is a speaker system with improved performance and refinement based on the highly evaluated Model10T.

Two 22.5 cm cone type woofers are installed in the low range.
The vibration plate uses a fiber bilaminate cone with damping treatment, and is driven by a large magnetic circuit with a 2-inch copper aluminum voice coil wound on a titanium bobbin.

The mid-range is equipped with 18 cm cone type mid-range.
The diaphragm uses a bilaminate cone similar to the woofer and is driven by a 1.5 inch voice coil. In addition, it uses a modulation ring and twin copper ring to reduce distortion.

A newly designed ribbon-type tweeter is installed in the high range.

The network section is a LinkWitz-Riley type with a design of 24dB/oct. It uses carefully selected parts such as polypropylene film capacitors, large air-core coils, nickel / steel core coils and high-purity wiring materials.

We have separate cabinets for mid-range and low-range use. Each cabinet is designed to optimize the functions and performance of each cabinet. In addition, energy absorbing material is laminated on thick MDF material, and it is carefully anti-vibration processed by internal bracing. The independent structure reduces the influence of unwanted vibration on each other.
While keeping the baffle area as compact as possible, the middle and high range cabinet has a depth and an air-cooled chamber inside to accommodate the network circuit connecting the high and middle range. In addition, the low range cabinet has a large baffle area and a strong structure that can support low range playback up to 20 Hz. By adopting a unique bass reflex system with a duct on the bottom, it is possible to install it freely without being restricted by the sound of the room.

Steel spikes are used for the legs.
The height of the spike can be adjusted, and tuning can be done according to the sound condition of the room.

Bi-wiring is supported.
