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 and the highest quality materials, while the dual
spider configuration includes a nomex spider that maintains its
compliance constant with the applied power. Moreover, the magnetic
structure construction generates a symmetrical magnetic field and, at
the same time, provides an efficient thermal path which contributes to
heat dissipation. Furthermore, its parameters has been optimized to
obtain an excellent bass response when used in small bass-reflex
cabinets. - High power handling (700 w AES)
Key Features
- Waterproof paper cone
- 4" edgewound copper voice coil with polyamide fiber glass former
- Optimum winding length for increased linear excursion
- Spiders of improved temperature behaviour: retain good mechanical properties at high power
- Designed for woofer applications
