Wow! When we started our search for our Strobes N' More Phantom Siren Speaker we had no idea so much work would be involved. Let me tell you it was well worth the work and the wait! Our Phantom 100 watt speaker features a waterproof and shockproof design giving you a longer life span at a lower cost. It features one of the smallest sound shields in the market so its much easier to mount than the larger speakers out there, and with today's smaller vehicles its a time saver. The sound shield is fully composite so no rusting issues EVER! The magnet was modified to get perfectly crisp sounds no matter which tone you are using and Public Address is clear as can be. Gone are the days of tinny sounding sirens and air horns, this speaker gives you both highs and lows like never before.
