RCF L10-750YK Mid-Bass

The L10-750YK is a professional mid-bass woofer featuring very high output and dynamics. The mobile equipment, used a 3" coil, fiberglass former and copper wire winding, has enable considerable improvement in transient peak response and has allowed good extension on mid-high frequencies. A specially designed M-roll surround guarantee a very low midrange distortion and perfect damping of the spurious resonances.
