The Pyle PLMR24 3.5" 200 W 3-Way Weather Proof Mini Box Speaker System (Black) features a rustproof grill that's removable for cleaning. These 3-way speakers provide the full spectrum of sound, thanks to the 3.5" aluminum injection cone woofer with a 24 oz. magnet for the low end, a 1.75" wide dispersion cone for the midrange and a 1" super dome tweeter for the highs. The built-in capacitor crossover network does all the hard work - you just plug them in using the quick connect terminals and hit 'play.' Bass reflex vent provides even more low end for your buck.
