The horn developed in order to demonstrate the wide band property of driver unit TD-4001.
It is adopted as Exclusive model2401twin and model2402.

The stabilized dispersion form by acer-mono plywood is taken, and the directive modification by 10kHz or more made difficult is enabled in the conventional large-sized horn.

The directive model pattern obtained from the actual sound field analyzation is investigated, and the acquisition of the stable listening area and the improvement in a feeling of an orientation are aimed at.
