Description
The SB Acoustics SB12PFCR25-4-COAX 4" (10cm) coaxial fiber/paper composite loudspeaker is driven by a powerful ferrite magnet. The resonance frequency around 60 Hz lies far outside the useful range, which means that the driver plays extremely linearly in the useful range and can be used optimally in the broadband range. The generously ventilated centring spider optimizes the rear compression behaviour to a maximum and provides additional cooling. The flattened basket ensures the smallest possible surface area on the baffle, making it easier to install the driver in small cabinets or tight spaces in the car.
