P30F is a 30cm (12″) subwoofer designed for a 28,3-liter-closed cabinet or a 40-liter-bass-reflex one. Regarding the performances, it announces 400 Watts RMS and a frequency response from 27 to 500Hz. The largest of the other 2 Flax subwoofers, it provides powerful bass without compromise and high SPL. Performance and high acoustic pressure lovers will be won over by this subwoofer!
The three Flax subwoofers consist of straightforward 4-Ohm voice coils which are perfectly suited for small enclosures (closed or bass-reflex). Several innovations raise their performance to an even higher level. Each model of subwoofer has a dual magnet, offering improved linearity and ensuring optimal magnetic power delivered to the voice coil, which features a new cooling system. Glass fiber has been used for the mounting of the voice coil, making it more robust while protecting the cone from the heat emitted. Last but not least, the new fixings connecting the cone to the voice coil and the spider to the basket improve reliability for extreme use (very high excursion).
