The heart and soul of any loudspeaker are its drivers, the transducers that, in response to the amplifier's demands, pressurize the air and generate the music. Each driver must be optimized for the task at hand. In the FR5, it quickly became apparent we could not source from even the most advanced driver manufacturers in the world the ultra-low-distortion high-dynamic output drivers we would need to build this remarkable 2-way stand mount speaker. We started with our planar magnetic tweeter. Moving air at high frequencies without coloration or distortion is a daunting task. On the FR5 we chose to go with a technology that has the speed of an electrostat with the dynamics of a cone. Planar Magnetics. This ultra-low distortion driver is equally driven with front and rear magnetic structures that offer inherent linearity through symmetrical “push-pull” neodymium motor structures and directly driven ultra-low mass diaphragms with none of the cone or dome breakup, inductance modulation, or hysteresis distortion that plagues traditional drivers. For the low end, we crafted a unique long-throw high-excursion 6.5" Curv woven Polypropylene woofer that matches the effortlessness and transparency of the planar magnetic tweeter. To lower distortion, we employed a unique split magnetic gap and a double copper Faraday ring for low, linear inductance and wide bandwidth, coupled with a single progressive Nomex spider with stitched-in lead wires. Lastly, to achieve maximum linearity and extended deep bass extension without the compression and distortion of ports, we implemented a rear-mounted high-compliance 6x9 inch passive radiator. Together, these elements create a stunning presentation of music in your home.
