  • Deep bass down to 40 Hz from 15 inch woofer
  • 460 W RMS Class-D amplifier drives 2000 W peak output
  • Three DSP presets tailor sound for monitor, DJ or live use
  • XLR input and output link mixers and additional amplifiers
  • Plywood cabinet cuts resonance for cleaner low-frequency response

Powered subwoofer for live sound

The PRORECK SP-15X is an active 15 inch subwoofer delivering 460 Watts RMS and 2000 Watts peak through a built-in Class-D amplifier. It targets DJs, bands and venues needing low-frequency reinforcement for weddings, parties, concerts or church services. The plywood enclosure reduces cabinet resonance compared with plastic alternatives. Two side handles simplify transport for mobile setups.

Thermals and power in normal use

The Class-D amplifier topology maintains efficient operation during extended performances, limiting heat buildup inside the plywood cabinet. An electronic crossover filters the signal from 40Hz to 120Hz, while the XLR high-pass output passes frequencies from 120Hz to 20KHz to companion speakers. The 4 ohm impedance and 70oz magnet structure keep current draw predictable under continuous bass output.

Upgrade path and when it matters

This subwoofer replaces a passive cabinet plus external amplifier rack, consolidating power and processing into one enclosure. The three DSP presets — Monitor, DJ Live — let you match the response to the venue without carrying a separate processor. The jump is worth it when you need a single 62.5lb unit that covers 40Hz to 120Hz and provides an XLR link output for stacking additional tops.

Questions about this item

How do I connect the SP-15X to my mixer and run tops from its high-pass output?

Use the XLR input for signal from your mixer, select the DJ Live or Monitor DSP preset, then patch the XLR high-pass output (120 Hz–20 kHz) to your full-range tops; set the crossover to 120 Hz on the sub so the tops receive only frequencies above that point.

What components will need attention after extended use?

The 70 oz magnet 15" woofer with its 3" voice coil and the Class-D amplifier are the primary wear items; monitor for voice-coil rubbing or amplifier thermal shutdown after heavy sustained output.

At what output level does the 460 W RMS limit become audible during a long set?

When average power approaches 460 W RMS the built-in limiter engages, reducing low-frequency output to protect the 4 Ω driver; you will hear compression and reduced bass extension before the 2000 W peak rating is reached.
