The P200 is an 8 ohm per speaker, 200 Watt Dual Driver Siren Speaker. It is made to handle any 200 Watt siren, including the Powercall 6-Adam and the DX5200. Some companies also use this for apparatus that have (2) 100 Watt sirens as the speakers can also be used individually, making it so you don't have to find space for 2 separate speakers. Powercallsirens HIGHLY RECOMMENDS using 2 speakers whenever possible for 200 watt sirens. This siren speaker is ONLY USED for apparatus with limited clearance. Please remember when using this speaker that it will NOT seem as loud as a normal 200 watt siren due to the amount of sound trying to be put through the single baffle. This speaker should only be used as a LAST RESORT for clearance issues. The dimensions of this speaker are 9x8x5.25. That is 9" from the back of the magnet to the front of the baffle, 8" from the farthest point Left to Right and 5.25" Tall.
