Compared to the PR:O 112 D2, this speaker offers extended low-mid and bass reproduction thanks to the 15″ speaker, making it ideal for standalone use without an additional subwoofer. The integrated DSP-based power electronics with 1,200 watts of power make the PR:O 115 D2 a powerful sound tool. The built-in MultiGrips allow safe and comfortable handling and make professional rigging a breeze by simply installing the TB-45N or TB-45NQ tilt brackets on them.
