Application : Power bass

The 18B500 loudspeaker are intended for high level, high power low frequency reproduction in ported enclosures. It feature vented die cast frame, 220 mm magnet structure, 3 inch voice coil and double spider assembly. This results in an very high sensitivity bass transducer for high power subwoofer application.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 180 L box enclosure tuned 43 Hz using a 40-400 Hz band limited pink noise test signal applied continuously for 2 hours.
2. Program power is defined as 3db greater than AES Power Capacity.

* Linear Mathematical Xmax is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg is the gap depth.
