2PCS 4 Inch Full Range Speaker 4 Ohm Speaker Round Speaker Unit Loudspeakers

Description:
Full-frequency units use magnetic circuit system, rare earth aluminum iron boron magnetic structure + short-circuit ring copper sleeve, which solves the transparency of medium and high frequencies. Cone mainly reflects the bass and mid-range and high-pitched sound. It uses cotton and hemp fibers and bark fibers. The high frequencies are transparent and not harsh. The mid- to high-frequency density is very good, very thorough, and the background is clean.
