Frequently asked questions
Which is better for live stage monitoring?
The PRX415M is purpose-built as a stage monitor with two-way design, horn tweeter for vocal clarity, and focused 90° x 50° coverage. The AC118S is a subwoofer only—it cannot function as a standalone monitor without additional full-range speakers.
Which delivers deeper bass?
The AC118S reaches 32 Hz at -10 dB and 40 Hz at ±3 dB with an 18-inch driver. The PRX415M's 15-inch woofer reaches 55 Hz at -10 dB, making the AC118S significantly deeper for sub-bass applications.
Which is easier to transport and set up?
The PRX415M at 46.3 lbs with compact footprint and carrying-friendly dimensions is far more portable than the AC118S at 32.3 kg (71 lbs). However, both are designed for professional touring environments.
Can these work together?
Yes—the AC118S as a dedicated subwoofer can pair with PRX415M monitors (or other full-range speakers) to provide extended bass reinforcement while the PRX415M handles monitoring duties, though this requires separate amplification and mixing infrastructure.
