RCF LF15G401 - 15" 800W 8 Ohm
The LF15G401 is a 15-inch woofer with linear frequency response characteristics and very high power handling.
The LF15G401 uses a fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround.
This combination provides remarkable strength and a peak to peak maximum excursion of 52mm.
Applications:
The LF15G401 is ideal for use in applications where incredible power handling, long excursion and perfect control is required.
Ideal for high quality professional bass reflex and bass-horn system.
The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or portable professional loudspeaker system.
Very good for 3 way, extended low frequency configurations.
Main Features:
- 4-inch, fiberglass inside/outside copper voice coil
- 1600W continuous program power handling
- 97 dB Sensitivity
- 30 Hz - 1.5 kHz Frequency range
- Dual spider design with silicon based dampening control

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.
