This Podium Pro Audio speaker was designed with pride right here in the USA. Customized built-in passive crossover perfectly mates the 30oz loudspeaker and high-frequency wide dispersion horn driver without losing essential midrange reproduction. The ports design smoothes air flowing in and out of the cabinet, reducing turbulence and port noise.

Only deluxe impact-forgiving aviation black carpet is used and tough ABS plastic corners help to prevent premature wear. Terminal consist of two 1/4" jacks and spring loaded quick raw wire connectors. Speaker mount for pole speaker stand. This multi-purpose Pro Audio Speaker was designed for many uses including Studio Monitor, PA, DJ and even Musical Instruments!! This speaker is built tough and built to last.
