Side-by-side comparison measured the MARCO at 151 dB compared to the Stebel and Wolo.

MARCO HORN DESIGN FEATURES THAT SET THE TORNADO AND HURRICANE HORNS APART FROM ALL THE COMPETITION.

LOSS OF ONE OR TWO TONES: The Marco design eliminates the sound loss by attaching the compressor using a bolt on design so the compressor cannot come loose from the sound unit, and to eliminate the ''O'' ring failures, an intermediary unit is between the sound unit and the compressor allowing for vibration absorbing so sound integrity is not lost.

Assembly of the ''O'' ring is changed to assure the ''O'' ring will not split when the compressor is installed - the intermediary piece accomplishes this.

The sound unit caps are heated prior to assembly and when cooled they shrink into place eliminated cracked caps and falling off the horn.

The flat electrical plug in blade connectors have a mechanical block to assure they will not press back into the housing. In addition the instillation of the blades is redesigned to assure no stress risers can be embossed into the blade and causing a stress riser failure of the blade.

The impeller of the Marco compressor is screwed on to the shaft of the impeller so it has no vertical movement, the competition loose impeller causes the plastic bottom of the compressor to loosen and fall from the compressor causing failure.

The plastic brush holder of the compressor is replaced with a metal cage eliminating the failure of the plastic holder melting.

Cold weather performance down to 0 degrees F available with a redesigned impeller compressor.
