This low frequency transducer is specially intended for the most demanding applications. Its design concept arises from the need of achieve a more resistant loudspeaker that matches the more and more power given by ultimate amplification systems. In order to accomplish that, almost every component of the speaker has been reconsidered: its voice coil has the benefits of an improved manufacturing process, made with the highest quality materials and the diaphragm has been carefully developed to give an extremely flat, smooth response. These characteristics make its integration in compact systems covering the low frequency range a straightforward task. Moreover, its parameters has been optimized to obtain an excellent bass response when used in small bass-reflex cabinets.

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.
