Fountek FW100B
The Fountek FW100B is a 4 inch / 100mm midwoofer featuring an anodised aluminium cone and ferrite magnet system. This small midwoofer has a large linear excursion of ± 4mm with a punchy bass response and good midrange extension. As to be expected with an aluminium cone drive unit, the transient response is excellent.
