Frequently asked questions
Can these two products work together?
Yes. The AC599 handles full-range content while the PRX915XLF adds extended low-end support. You would set the PRX915XLF crossover to 80–120 Hz and high-pass filter the AC599 inputs to avoid frequency overlap, creating a complementary two-tier system.
Which is better for a small touring DJ setup?
The PRX915XLF is ideal as a subwoofer component because it includes built-in amplification, Bluetooth control, and daisy-chain outputs. The AC599 is a full-range speaker, so you'd need a separate subwoofer or amp to use it in a portable PA context.
What's the power requirement difference?
The AC599 is passive and requires external amplification rated for 500W program power. The PRX915XLF is self-powered with a built-in 1000W RMS Class D amplifier, needing only an AC outlet and audio input cable.
Which handles lower frequencies?
The PRX915XLF extends down to 36 Hz (−10dB), making it a dedicated subwoofer. The AC599 is a full-range 2-way system optimized for mid-to-high frequencies with substantial but not extended low end, typical of venue speakers.
