These 12 Inch Monitors have a minor manufacturing flaw. They are in perfect working order and perform just as any SA-12MT would! The flaw is on the jack plate. These monitors are supposed to come with Dual 1/4" and Dual Speakon connections. These were Manufactured with Dual 1/4" and a Single Speakon. They also have an indicator light on the jack plate that states "Protection Activated". This is NOT the case and this is simply an indicator light showing that there is power to the unit. Again, the indicator light is not a clip indicator, or an indicator letting you know that Protection is in place. IT IS A SIMPLE POWER INDICATOR LIGHT. This is why we are discounting these speakers and they must go! Please see the photos of the jack plate!It’s important that you can hear your music on stage. This wedge shaped, 12 inch monitor delivers every sound clearly with a 12 inch speaker, 4” x 10” Titanium Horn Driver, a frequency response of 45Hz to 20,000Hz, and 200 watts RMS, 400 watts peak power. Great quality monitors are very hard to find, especially at a decent price. The Seismic Audio brand was designed to make the professional musician, as well as the musician low on cash, sound great. With your purchase, you will receive a single monitor pictured and described above. So, put it in your cart today and get ready for years of trouble-free, crystal clear sound!
