The coaxial arrangement of the low and high frequency drivers results in a directivity response free of irregularities, which helps overcoming microphone feedback problems. The front baffle is angled 35˚, which is adequate for typical stage monitoring situations.
The enclosure is manufactured from Wisa® Birch plywood and is finished with a durable catalyzed polyurethane paint that provides protection against the elements and abrasion. The wedge shape minimizes panel vibration and cabinet modes.
The ST-32 has a polyamide powder coated steel grille to protect the loudspeaker components. The grille is covered with a fabric that provides resistance to wear and tear, protection from dust and dirt, and is both acoustically transparent and flame retardant. An integral 35mm socket can be used for tripod mounting, extending the range of applications for the system.
