Product Information

Description

The very stromg magnetic unit, with 15mm thick plates and specially designed suspensions ensure an excellent control of amplitude of over +/- 12millimeters.
The special cooling system with forced air ventilation offer a great haet dissipation and the minimum levels of power compression available on the market.
Voice coil construction, suapensions and cone materials are upgraded in order to withstand up to a Kilowatt RMS power.
The L18P300 finds its best application in both bass reflex and band pass system.
Its capacity to reproduce extremely low frequency along with extraordinary definition make it a no compromise woofer in its category, ideal for both live and recorded music.
