Earthquake MiniMe P8/W 320 W 8 Inch Powered Subwoofer With Passive Radiator and White Laquer Finish

Earthquake MiniMe P8 320 W 8 Inch Powered Subwoofer With Passive Radiator and Piano Black Laquer Finish
  • The MiniMe MKV has a much smaller cabinet than the exsisting MKV models, and accommodates a tiny 8 in. driver new to the Earthquake family,  providing a suprising bass response and high output unlike any other 8 in. on the market. The SLAPS patented passive radiator ensures that even this tiny area moves as a absolute piston right through the subwoofer bandwidth and beyond.
  • Driven by our 320W Class-D amplifier, this driver can produce king-sized amounts of bass power with absolute control - enough for most large high-end projects.
  • All-inclusive controls are provided so that the subwoofer can be integrated seamlessly into either a multi-channel or 2-channel installation. 
  • Features:
  • • Built in 320-Watt, high efficiency digital amplifier
  • • Long throw, premium quality drivers
  • • Convenient compact size
  • • Automatic signal-sensing turn-on and stand-by mode
  • • Perfect for all sub applications
  • • Operation status LEDs
  • • SLAPS Patented Passive radiator technology
  • • RCA & high level inputs
  • • Selective variable crossover
  • Input Sensitivity Full Output: 240mVrms from left input with volume control at max, 90mVrms with volume control fully clockwise and both RCAs used. 
  • Frequency Adjustment:
  • 50Hz - 160Hz 
  • Phase Shift: 0-180° 
  • High Cut Filter: 35Hz-100Hz
  • Output Levels: Greater than 108dB peak SPL (includes room gain) from 25Hz to 90Hz
  • Sub Operation Switch:
  • In LFE position, the frequency adjustment becomes disabled and the subwoofer runs in a Full range mode, from 20Hz - 2kHz. While in Sub position the subwoofer reverts to the manual frequency adjustment, allowing the user to operate and fine tune the subwoofer.
  • SuperNova MiniMe MKV 

  • Power 320 Watts / 160-Watts RMS 
    Driver  8” high-performance with extra large magnet and long throw mechanical design yield very high back emf. The result is extraordinarily high operating efficiency that is, more acoustic output for each watt of input. Also includes Earthquake's Patented 8" SLAPS (passive radiator)

Earhtquake SuperNova MKVI 12 Inch / 15 Inch Subwoofers
    Earthquake Sound Corporation is proud to introduce the next generation SuperNova MK Series.

    The new SuperNova MKVI includes an all-new recessed amplifier with built-in room correction. Many companies claim that they have room correction built into their amplifiers. However, their subs only use level adjustment by volume. 

    Earthquake's new SuperNova subwoofers with built-in IQ amplifiers deliver the tools you need to correctly adjust a room to precision audiophile status.

    Most subs with built-in amps use a simple equalization method that does not correct the rooms' "phase" related problems. The new SuperNova MKVI subs have true room correction that take time reflections and refractions into consideration. These state of the art amplifiers fix both the arrival time and equalization while others try to equalize rooms by adjusting the volume. Would you call that room correction? The new 99% efficient SuperNova subs with IQ amplifiers address the actual phase correction problem along with the room EQ. 

    Room Correction: 20, 30 and 40Hz Room Equalization With 12dB range and Boost. 
    Optical Distortion Limiting Circuitry (OoDL): ODL was created to eliminate audio amplifier input stage clipping without distorting the audio signal. 
    Overdrive: Overdrive is a patented feature that allows the Supernova amplifier to generate maximum output with virtually any level of input audio signal. 
    SLAPS Passive Radiator (Follow link for more info) 
    Full range speaker outputs high level audio input Signal detection circuitry Variable, 24dB per Octave, low pass filter 110 / 220 power connector
