The B218 has an operating frequency range of 30 Hz to 160 Hz with a maximum peak output of 145 dB. It's a rugged, lightweight centrally charged enclosure housing two ND18" woofers. These advanced components, each fitted with 4 inch voice coils, provide the highest output power-to-weight ratio of any speaker system in its class.
The cabinet consists mainly of two different volumes with different charging techniques. The back sides of the two drivers are tuned by a reflex tunnel, while the front area of the diaphragms is charged by a truncated horn throat that extends the frequency response up to 160 Hz. The carefully designed concept can stand all the electrical power the B218 is stated avoiding any bottoming effect. The system is rated 2400 Watts PGM on a 4 Ohm load and shall deliver 106dB with one watt input @ one meter in half space conditions and 136 dB continuous, 145dB peak SPL.
The B218 is constructed of 18 mm Finnish birch, pressed and glued together for maximum strength and finely finished in black textured paint. The cabinet is 77 cm deep (without wheels), 75 cm tall and 57,5 cm wide. Extensive internal bracing guarantees long term stability even in the most demanding conditions. Eight handles allow easy transportation.
