A mid-high-end midrange speaker with a very natural sound, paper cone and solid cast aluminum construction. Wide frequency response allows it to blend well with various midbass and tweeter combinations. These come with nice machined aluminum black anodized mounting rings and contoured hexagon grilles. The QK3 pairs well with the QK6 midbass and QK1 tweeter pairs, but it can be used as a nice addition to any 2-way components set due to its wide frequency response and ability to blend well with any system.
