The FSX8-4 is a powerful 8-inch, 4 Ohm, pro audio mid-range loudspeaker. Featuring a vented back plate design for increased thermal cooling, as well as a high temperature 1.5-inch copper voice coil, this speaker is capable of operating at the loudest volumes very efficiently.
Conservatively rated at 175 watts RMS power, and 350 watts max power, the FSX8 features an impressive 25 oz ferrite magnet, which provides the driving force behind the crisp and clear sound that is output by these speakers. When looking for a pro audio mid-range speaker, the FSX series is the obvious choice; combining power, sound clarity, and reliability.
