Earthquake Granite-52 - głośniki do użytku zewnętrznego


The Granite-52 speakers and Granite-10D subwoofer –  part of the  new  ROCK-on  outdoor  speaker  series,  are  specifically designed to  imitate a rock appearance and easily blend  in with any  outdoor  environment.

Made  with  UV  treated,  weather-resistant  enclosure materials  and  durable  epoxy  resin  construction,  the ROCK-on speakers can withstand  the demanding outdoor elements.

Granite-52 are a pair of rock speakers with a 5 ¼ inch woofer and a ½ inch tweeter. They serve as your left and right speakers and have an amazing frequency response that is unmatched by any other rock speaker. They produce a clean, accurate sound.

The ROCK-on subwoofer, the Granite-10D, features high power crossovers that reduce distortions and deliver pure sound. Also, Granite-10D’s  port  is  “S”  shaped  so water  cannot  get trapped  inside.

The Granite-10D brings bass to your outdoor space, something that is greatly needed in today’s rock speaker market.  Combined with the Granite-52 speakers which have a matching finish, you can turn any backyard into an entertainment center.


Wiring Options

Earthquake Sound’s XJ-300FR Stereo amplifier can be used for your ROCK-ON 2.1 system. In tri-mode wiring the user can connect the 2 channel stereo and the mono at the same time. The subwoofer connection below demonstrates a series wiring formula which has a load impedance of 8-Ohm.



To simplify the wiring process, use Earthquake Sound’s SWAT 2.4 Wireless Transceiver:
    1. Connect the rock speakers and subwoofer to the XJ-300FR amplifier as shown above.
    1. Connect the SWAT 2.4 Receiver to the XJ-300FR amplifier through the RCA inputs.
  1. Connect the SWAT 2.4 Transmitter to any music player that has a mini jack or RCA output. Note:  Make sure both the Transmitter and the Receiver are connected to a power source, either through the DC power supply or the USB port.
