To get this performance the magnetic structure use a high flux neo disc & the cone assembly a fibre loaded exponential shape along w/a high excursion triple roll, constant geometry surround.
The fiberglass former & aluminium voice coil provide a very high power handling maintaining a light mass & a proper Q factor for bass alignment.
* Ideal where is required extremely high power handling, very high efficiency & perfect linearity.
Is the ideal 12-in mid-bass woofer for reference high fidelity, high performance midbass application in compact 2 way system.
