RCF L18P300 - 18" 1000W 8 Ohm
In production for over 10 years, the L18P300 is an industry standard.
The very strong 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 heat dissipation and the minimum levels of power compression available on the market.
Voice coil construction, suspensions and cone materials are upgraded in order to withstand up to a Kilowatt RMS power.
Applications:
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.

Our database of parts includes a wide range of products, and in many cases offers cost effective alternatives for repair. Alternatives are loosely grouped into three types:
Original - Usually an exact match to the original product, and just the 'standard' part from the factory which gets rebadged by manufacturer with their own brand and part number. Occasionally, there are subtle tweaks made from the standard part, but its virtually impossible for us to determine this. If we have listed the part as Original, it means we are confident the performance is the same.Aftermarket - Aftermarket parts often become available from factories in the far east once the original part is no longer manufactured. They are intended to be a close match, and provide a cost-effective alternative.
Equivalent - These are alternative options, which provide very similar performance, but are not the same as the original. In some cases the performance may actually be improved. We have used both our own experience, and feedback from customers in generating list of alternatives. Alternatives like this are useful when the original part is no longer made, there is no aftermarket option, so the only choice is to upgrade with the nearest current equivalent product.
