Thanks to the combination of the aluminium basket developed and drawn by our R&D with an optimized ferrite magnet circuit, this speaker is able to handle 2800 Watt musical power.
Furthermore, the progressive double cross spider, another development by our R&D consisting into two spiders glued together in cross position, grants stability and strength to the whole system.
The cloth surround with triple rolls guarantees high and linear excursion, avoiding mechanical distortion and generates clean bass tones.
This speaker increases the reference quality to the 18" speaker used as Subwoofer.
18 PF 4 is a speaker for Sub-Woofer application. It is a 18" with 100 mm sandwich voice coil with copper wire and fiberglass former.
