Steel, flush mounting type square frame. Rubber roll surround.
Doped/coated paper cone. Ventilated center pole and large magnet.
Suitable for 3-10L sealed enclosures, but best bass results are
obtained from a 5-12L ventilated box. Also very suitable as a
midrange offering very low crossover frequency and fantastic
voice reproduction on and off axis for a “neutral” midrange.
