Earthquake - MKV-15Piano - 15" Powered Subwoofer (Single)

Earthquake - Supernova Luminous LU-15 - Powered Subwoofer

When Earthquake Sound Corporation lunched the MK series of powered subwoofers, it immediately put home theater subwoofers on steroids. While THX 1 and 2 required to have 35Hz at 105 dB, the MK series laughed at those numbers. As tested by many, Earthquake’s MKIV 12 beat all subwoofers on the market (measured by Richard Hardesty of Widescreen Review, Dr. John E. Johnson of Secrets of Home Theater and High Fidelity, and Steven Stone’s Stereophile Guide to Home Theater). Earthquake Sound is pleased to announce the newly released Supernova LU-12 and LU-15 that further expands on the Supernova series of home audio subwoofers. Powered by the Luminous 1000 amplifier, these subwoofers pack power, features, and performance in an extremely compact enclosure with a luxurious black piano finish.

ODL Circuitry
ODL (Optical Distortion Limiting) is an LED/LDR circuit that convertsthe analog audio signal to light and optically couples it to the driverstage. This prevents the amplifier from clipping when the gain is settoo high which limits the distortion to near nil levels and maximizesperformance of the Supernova Luminous.

MAGMA-X Active Driver
With a massive moving structure and double spider, the extremelyhigh excursion MAGMA-X active driver enables the Supernova Lumi-nous to achieve deep, dynamic, and hard-hitting bass response thatwe all desire in home theater setups.

New SLAPS V2 Passive Radiator
A newly designed SLAPS passive radiator allows the Supernova LU-12/15 to reach dominating LFE without increasing the enclosurevolume. The patented design of the SLAPS helps the subwoofereffortlessly produce more bass at sub-harmonic levels while reduc-ing the load on the LM1000 amplifier. Simply put, the LU-12/LU-15will suck and blow more air than any other subwoofer on the planetwhile producing massive bass down to 15Hz with absolutely zeroport noise.

Balanced LFE & XLR Input
The use of a fully balanced XLR input can be used in cases when thedistance between the Supernova Luminous and the audio source isexcessive and susceptible to noise interference. Use the selectorswitch between the RCA and XLR inputs to select the desired inputmethod.

Variable Crossover Filter
A 4th order 24dB/Octave variable crossover filter from 50–150Hz isdesigned to control the subwoofer’s cutoff frequency. the generalrecommended setting is in the 2 o’clock position.

Phase Shift Switch
A 0º–180º phase switch allows users to synchronize the subwoofer toobtain a better and more precise bass response.

+12V Trigger Input/Auto
This feature allows the user to power on the Supernova Luminousfrom your home A/V receiver. When the A/V receiver is turned on, a12V signal is sent to the subwoofer and will power on while thepower switch is on the off position.
