SubMersive F2+ Features:


Amplifier & Controls:

  • 4000W continuous power amplifier (with slave connected)

    • 2400W continuous power as a single unit

    • Capable of driving our passive SubMersive F2-Slave to the same levels as a single F2+

    • 4 Conductor Neutrik SpeakON connection for powering optional slave unit

    • US designed, high current, high duty cycle, class D amplifier design

    • High efficency of up to 95% for maximum power from available home circuitry

    • Fully Manufactured in the USA (board level up)

    • Nominal 120V operation (HP i+/F2i+ version available for 208-240V operation)

    • IEC Power Cord (10' length included) - right angle plug available

  • Connection options

    • 12V trigger and auto sensing - 3.5mm mini-cable connection

    • LED indicator for power, standby or error codes.

    • XLR -Female input (LFE/mono) with looping, XLR - Male output (internal Y connection)

    • 2 summed RCA inputs for LFE or Stereo inputs

  • Digitally programmable, detented, control knobs for precision adjustment and tuning

    • GAIN (volume) control – wide range for matching any system

    • LF Adjust (low shelf/adjust extension/room sizing) enabling adjustment of low frequency extension from 12Hz to 27Hz or +/- 8dB shelf (see graphs).

    • Low pass crossover 30-120Hz + 200Hz, precise, digital, Linkwitz-Riley 4th Order fitlers (24dB/oct)

    • Delay adjustment - 0-20ms for multiple subwoofer blending

  • Proprietary DSP performance optimization

    • Smooth anechoic/outdoor frequency response

    • Carefully optimized, proprietary overload protection – never fear for the well being of your subwoofer while the SubMersive maintains composure to much more intense playback levels

    • Smooth power response to 200Hz for seamless crossover with compact speakers

    • Shallow sealed roll off maintained in all LF Adjust settings

    • Shallow low frequency roll off typically yields 8-12Hz in-room extension

    • LF Adjust shelving & room size adjustment allow for a best fit with large to small rooms
