GQ is the newest series in the lineup of speakers from Grund Audio. The GQ Series includes five new self-powered models and are ideal for performing musicians and DJ's as well as being an outstanding choice for event production, corporate AV, and education.

The GQ Series models consist of three 2-way, one 3-way, and one subwoofer. The GQ-153A three-way has a 1-inch high frequency compression driver with rotatable horn, an 8-inch mid driver and a 15-inch low frequency transducer. Being very versatile makes it a great choice for a wide range of sound reinforcement applications.

The Grund Audio GQ-153A is finished with Tour Coat™ to provide a thick, durable finish to resist scratches and also helps protect the inner components by keeping moisture and dirt at bay. The Tour Coat™ finish maintains its appearance for years.

The self-powered GQ-153A is rated at 600 watts. The versatile multi-channel inputs found on this amplifier include an XLR balanced microphone input, a 1/4-inch line input, and RCA inputs for use with CD players and similar equipment. Also, any two sources can be mixed internally.
