Passive Subwoofer
2400W | 133dB |33 Hz- 160 Hz

ESBR18 is a passive direct radiation subwoofer system composed of a single 18FW speaker with a 3” coil and 20 mm winding depth, double layer and sandwich to boost system power, as well as a new forced convection circuit that works to reduce the effects of coil heating, improving the system’s overall performance as a result. As part of our company culture, all our systems are developed under a single philosophy: to deliver the highest possible quality in terms of both materials and overall system design. In the E11EVEN Powered series we use the same birch plywood as our touring systems for a tight, natural warm sound found nowhere else on the market
