The 1526 is intended for use primarily in subs, monitors, or low frequency instrument enclosures. 

The APX-1526-4 incorporates a heavy cast aluminum frame basket, which resists deformation and aids in heat dissipation.  The mounting specifications are standard 8 bolt and the baffle cut-out size is typical of many other standard pro audio loudspeakers.

The high power handling capacity and heavy duty construction of the APX-1526-4 is designed for pro touring or fixed sound reinforcement use, while the low distortion and well balanced response make it suitable for critical high level monitoring applications.
