Woofer
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.
