Thiele-Small parameters are measured after a high level 20 Hz sine wave pre-

conditioning test.

High efficiency 10" woofer using a FEA computer designed high

energy Neodymium magnet assembly, extremely lightweight

(only 1.9 kg). The aluminium basket is designed to effectively

dissipate heat during demanding use at full power, reducing

power compression. Recommended for compact two-way

systems where power is limited to 300W.
