This is a great sounding pair of PAS T1200 speakers. They work as they should and sound great and come from the Professional Audio Systems' Target Series. They can be used as mains or monitors. I was surprised at the quality of sound that comes from these. There are two 1/4" and speakon connections on the back of each and a high frequency attenuator. They feature a 12" woofer and compression driver in each cabinet. They are rated for 250w RMS and reproduce great sound. They are a litte dirty from normal use. I have used these personally. They measure about 24"H x 15"W x 16"D each. I have cables, mic stands, speaker cabinets, and more gear listed in other listings.
