Wom250_vPA is engineered to cover 50 - 850Hz (-3dB) in a very compact enclosure (sealed or vented).

The advanced motor structure is built with Ø116mm voice coil, high grade ferrite magnet and it is demodulated by 2 Aluminum rings.


This woofer allows new product design, such as low profile professional system with very low THD rate and high power handling.
