PF03N | 3″ PA Audio Low Distortion Fullrange Speaker

Description

CFS PF03N drivers are optimized using FEA to give a rising HF response. This results in a noticeably wider dispersion characteristic to higher frequencies than conventional speakers of this size.
 
The transducer uses high enery neodymium magnetic to achieve a very high acoustic output to weight ratio.Chassis are purpose designed for maximum free air movement, while stiff and treated paper cones remain rigid to higher frequencies, delivering a smoother response in the critical listening band.
 
 
Half roll polycotton surrounds enable greater excursion and lower responance frequeancy for small diameter cones. they also provide damping of unwanted resonances and sustained centring control at exatremes of excursion.
 
 
The PF03N employs a large 1”(25.9mm)diameter voice coil that Provides an AES rated 30 watts of continuous power handing and a full 60 watts of peak power handing, the PF03N utilizes CFS under damper venting technology to reduce turbulent airflow near the voice coil that provides good conversion efficiency and high thermal power handing.
