FAVO MBR218 passive subwoofer

PRODUCT DESCRIPTION:

MBR218 - a sub-bass module based on two 18" neodymium speakers with high specifications and an extremely high Xmax. Designed for outdoor events, club rooms, and discos.

The MBR series—Modular Bass Reflexes—is designed around the modular principle. Using the same arrays, we can create various structures, which is particularly important for bass. Properly positioning the bass modules allows for things like controlling the directivity of the bass beam, maintaining a high SPL with increasing distance, and adding low frequencies. MBR modules are also exceptionally easy to create cardioid structures, which can significantly reduce the sound pressure behind the bass.

All NAW Performance Audio products designed for outdoor use are coated with Line-X waterproofing and are completely weatherproof.

BASIC TECHNICAL DATA:

Two 18" speakers in a rectangular bass-reflex enclosure made of waterproof Baltic plywood with a polyurethane finish. Four pairs of carrying handles are positioned at a height that facilitates carrying in two planes and allows for easy stacking on top of each other and on a rolling platform. A tripod flange with M20 thread (traditional available upon request). State-of-the-art speakers are used, assembled to our specifications at the B&C Speakers factory in Italy.
