These are a clone of the RCF C3110 Speaker, but are actually better quality than the originals. Mid-Top cabinets are based on the RCF C3110 design, but with uprated drivers. The mid-bass driver is a 10 inch RCF L10/750YK, it has a 3 inch voice coil and rated at 350w RMS, 700w program. The HF driver is an uprated RCF ND1710 40w RMS, 80w Program Titanium Compression driver. Fitted to an RCF HF94 cast aluminium 90×40 horn flare. The 2 drive units are fed from a 500w RMS 2000Hz Beyma FD250 crossover. The cabinet also has loop in loop out Neutrik sockets on the rear. It also has rubber feet fitted and has aluminium top hats on underside for stand use. Cabinets are constructed of 3/4inch 14 laminate birch ply, glued and biscuit jointed as above and very heavy. Cabinets are also fully lagged with acoustic wadding. Cabinets have powder costed steel grille fitted. Dimensions 600mm High x 320mm Wide x 290mm Deep. These sound absolutely lush with lovely deep warm bass. Probably one of the best small PA cabinets I have heard and unbelievably over engineered. Collection Only From Winchester.
