The QM-12DC 2-way full range loudspeaker has all the benefits of the 10DC with the added benefit of more bass and efficiency. The 12" and 1" dual concentric driver has been optimized for vocal presence and has a very uniform frequency response. This will give higher SPL before feedback from a very compact low profile multi-purpose speaker. The 10DC is a great versatile tool for any audio application that needs a mid-powered stage monitor, wide dispersion FOH speaker, delay speaker or addition to a QM1000A system.
