RCF HDM 45-A Active Powered Speaker

Don't compromise on sound quality. The RCF HDM 45-A loudspeaker delivers powerful sound thanks to smart design, premium components, and FiRPHASE processing.

The HDM 45-A speaker boosts the performance with a top-quality two-channel amplifier, RDNet networked management, RCF precision transducers, the FiRPHASE processing, and a rugged cabinet. While being one of the most powerful speakers in composite material in its category, it delivers clear, detailed and smooth sound from low to very high levels, with low distortion and fast transient response. The HDM concept is inspired by the touring industry, packing in an elegant and lightweight cabinet the maximum reliability and strength for intensive use on the road. Perfect as a main front of house speaker in PA systems, high-powered floor monitor, or unobtrusive infill system when combined with the RCF HDL System speakers.

First of all make sure you adjust the gain. It's digital and out the box it comes cranked up to 0 which is +10 on a normal gain knob. once i figured that out, and the settings on the new sub, hands down these are the best top speakers below line array. you can hear the clarity at loud volumes with no distortion or hissing. You do have to EQ it a little bit but it coupled with a powerful sub WoW!!!! I run it on L1 no limiter on the RCF and 60hz cross over on my yamaha dxs18xlf-d sub. Decent bass without a sub... But as a DJ I plan I on using 2 Subs...
