About Earthquake Sound Corporation

For over 28 years, Earthquake Sound has been producing a variety of high-quality audio products that have impressed audiophile communities around the world. It all started in 1984 when Joseph Sahyoun, a music freak and Aerospace Engineer unhappy with the existing loudspeaker technology and performance, decided to put his advanced engineering knowledge to use. He pushed technological boundaries to the limit to create the kind of subwoofer he could live with. Earthquake quickly created a name for itself in the car audio industry and became well known for its powerful subwoofers and amplifiers. In 1997, using his existing expertise in the audio industry, Joseph Sahyoun expanded his company to home audio production.
Earthquake Sound has since evolved into a leader in the home audio industry, producing not only subwoofers and amplifiers but surround speakers and tactile transducers as well. Engineered by audiophiles for audiophiles, Earthquake Sound audio products are meticulously crafted to reproduce each and every single note perfectly, bringing your home theater experience to life. With true dedication and full attention to detail, Earthquake Sound engineers continuously develop new and better products to meet customers’ needs and go beyond their expectations.
From mobile audio to prosound and home audio, Earthquake Sound has been selected as the winner of many prestigious awards based on sound quality, performance, value, and features. CEA and numerous publications have awarded Earthquake Sound with over a dozen design and engineering awards. Additionally, Earthquake Sound has been granted many design patents by the USPO for revolutionary audio designs that have changed the sound of the audio industry.
Headquartered in a 60,000-square-foot facility in Hayward, California USA, Earthquake Sound currently exports to over 60 countries worldwide. In 2010, Earthquake Sound expanded its export operations by opening a European warehouse in Denmark. This accomplishment was recognized by the US Department of Commerce who honored Earthquake Sound with an Export Achievement award at the 2011 Consumer Electronic Show.

System Installation Considerations

There are several factors to consider before installing Earthquake Sound’s MiniMe P63 Subwoofer.

• What are the intended listening zones?
• From where in each zone will the listener prefer to control the system? Where will the subwoofer be located?
• Where will the source equipment be located?

Connection Tips

• Keep all power cords away from all signal cables to prevent humming from induced noise.
• Choose reliable signal cable cords (Earthquake Sound also specializes in high-performance RCA cables and patches).
• All speaker wires that are ran through the walls should be twisted type to reduce potential hum noise pick-up.
• It is best to use a grounded electrical outlet to power the amplifier. Lack of input ground reference could be unsafe. Consult with your electrical contractor about proper grounding.

Safe & Proper handling

The MiniMe P63 subwoofer is considerably lightweight and easy to maneuver. However, we encourage you to take precautions when unpacking the unit to prevent any possible damage to your MiniMe P63. We further suggest the following:

• Do not apply pressure or push against the face of the speaker as this will cause irreparable damage to the cone and suspension.
• When carrying the MiniMe P63, make sure that the speakers/grilles are away from your chest, eliminating the chance of pushing against the face of the speaker.
• Do not drop the MiniMe P63 or subject it to sudden shocks. This will damage the external finish and weaken the enclosure, creating air leaks.
• Avoid exposing the MiniMe P63 to moisture. Water will damage the structure as well as the amplifier and speakers.
• Cleaning the MiniMe P63 is best done using a soft cloth. If needed, use a mild detergent with water. Like any other electrical unit, always unplug the unit before cleaning it.

Unpacking the MiniMe P63

• Keep the original carton and packing materials for future shipment or storage.
• Check for any visual signs of damage. If you encounter any concealed damage, consult your Earthquake Sound dealer before proceeding with the unit installation.
• Retain the sales receipt as it establishes the duration of the limited warranty and provides information for insurance purposes.

The MiniMe is packaged well for safety. We highly suggest having a padded surface when unpacking it.
Step 1
On a padded surface, carefully place the box on its side to remove the bottom packing tape and staples.
Step 2
Without tilting the box too much, tug the bottom flaps outward and keep the protective foam in place.
Step 3
Gently reposition the box upright.
Step 4
Slide the box off, minding the protective foam on the top, bottom and sides of the subwoofer.

What Makes a MiniMe?

Digital Class “D” Amplifier

The MiniMe P63 amplifier utilizes the advanced class “D” circuitry with over 90% efficiency, allowing it to continuously perform without getting hot.
The 500-Watt peak power amplifier is fully equipped with 40 – 180Hz frequency adjustment control, 0 – 180° phase adjustment, low-level RCA input, auto signal sensing, and shielded components.

Premium Long Throw Drivers

The active driver installed in every MiniMe P63 is specifically designed for accurate reproduction of bass and sub-bass frequencies. Built with TCT (Turbine Cooled Transducer ) Technology, stitched tensile leads, anti-wobble cone construction, and a reinforced dust cap, the MiniMe P63 driver effortlessly produces phenomenal bass with extremely low distortion while staying cool the entire time.

Passive Radiators

The MiniMe P63 is equipped with two passive radiators. One on each side of the active driver. This increases the efficiency and capability of the subwoofer for ultra-low frequency reproduction. Coupled with the premium long throw active driver, the passive radiators enable the MiniMe P63 to deliver louder and more powerful bass without using more power from the amplifier.
Luxurious Piano Gloss Cabinet

Available in five different high-end finishes. The deep luxurious piano lacquer begins with a thorough sanding and priming, followed by multiple applications of colored lacquer with an additional fine sanding between each layer, and finished with a smooth, high gloss clear coat. Available in black and white piano gloss, as well as in limited edition color finishes red, silver, and yellow.

When it comes to elegance and style, the MiniMe P63 delivers.

Control Panel Overview

1. AUTO/ON/OFF Switch
   This is a 3-way switch. When ON, the amplifier will remain on regardless of signal presence. When set to AUTO, the amplifier will only turn on when audio signal is detected. Additionally, the amplifier will go to sleep/standby if it does not detect any signal after about 11 minutes. When set to OFF, the amplifier will remain off regardless of signal presence. Note that the main power switch must be ON for this feature to work.
2. LED Power Signal Indicator
   This LED indicator reflects the main power status of the amplifier as well as the state of the amplifier (whether the AUTO Sensing is on/off and whether signal is being fed to the amplifier). Note that this LED will only light up when the main power switch is in the ON position.
3. Low-Level RCA Inputs
   These RCA input terminals allow the MiniMe P63 amplifier to receive signal from the amplifier or receiver that is powering the surround speakers
4. 115V/230V AC Selector
   The MiniMe P63 can operate in a 110-120V or 220- 240V environment. The subwoofer should already be set to the correct voltage depending on your region. If not, make sure the sub is not connected to any power source. Set the selector to the required power setting prior to reconnecting the subwoofer to a power source.
5. Main Power Switch
   When switched OFF, the amplifier will remain off as there is no AC power being fed into it. We highly recommend keeping this switch OFF when the subwoofer is not being used for an extended period of time.
6. Volume Control
   This knob allows the user to control the volume of the subwoofer. Always start at the lowest setting and slowly increase the volume until the desired subwoofer level is reached.
7. 0-180° Phase Adjustment
   This 0° – 180° switch allows the user to synchronize the subwoofer to obtain a better and more precise bass response..
8. 40-180Hz Frequency Adjustment
   This knob allows the user to set the subwoofer’s cut-off frequency. Signals above the set crossover frequency will be gradually rolled off to prevent them from interfering with the surround speakers.
9. BT/WiFi Power Port
   This USB port provides 5.2v of power capable of powering a Bluetooth™ or WiFi adapter (sold separately)
10. Main Power Supply Input
    Be sure to have the MiniMe P63 power switch in the OFF position before plugging the subwoofer into a power source.

Placing Your Subwoofer(s)

You often hear the term “subwoofers are non-directional.” This is not true. It is harder to choose subwoofer placement when low frequencies are crossed. The wider the room, the more directional the subwoofer. The easiest solution is to use two (2) subwoofers, feed a mono signal to both, and place them in the front, one on the left and another on the right.
While having two (2) subs is better than one, the MONO signal that drives those subwoofers keeps them from projecting the three-dimensional images in the sub-harmonics. Using two (2) subwoofers allows you to cross the subs up to 150Hz sound quality, imaging, and staging. In some applications, you might have small front speakers or planar speakers. The two-front-subwoofer system is an excellent solution to planar speakers’ low-frequency response early roll off from 150Hz on down. When placing these subwoofers in close proximity to the stereo satellite, the subs will enhance low-frequency extension. It will be better to have a stereo subwoofer to help in the lower bass notes and their placement.
Suppose you have only one (1) subwoofer in the room and it is placed on the right side of the room. If a bass guitar player was standing on the left side of the stage and played an EE note (42Hz), then the sub will also respond to that from the right side of the room and completely destroy the stage.
You will see illustrations showing the two (2) different suggested setups. In each of them, note the breakaway and the image separation represented by the black and gray arrows.

The black arrows represent the subharmonic frequencies.
The gray arrows represent the lows, mids, and highs as they follow the action.

The best response is achieved when the subharmonic frequencies are dynamically synchronized with the rest or the audio system, the black and gray arrows are identical.
Single Subwoofer Setup
This is a GOOD setup. The subharmonic frequencies (black arrow) always move towards the sub in the single sub setup while the lows, mids and highs (gray arrow) follow the action.

Placing the subwoofer in the corner of the room will produce a more boomy effect, often preferred for movies and soundtracks

Notice the breakaway and image separation is less in this setup than the single subwoofer setup.. For a music application, place the subwoofer as shown above or against the front wall, about a third of the room width.
Dual Subwoofer Setup with Mono Signal
This is a BETTER setup. In a dual subwoofer setup, the subharmonic frequencies (black arrow) always move towards the middle of the room while the lows, mids and highs follow the action (gray arrow).

Notice the breakaway and image separation is less in this setup than the single subwoofer setup.

Connecting Your Subwoofer(s)

Low-Level Setup – Single Sub
This is the best way to drive an audio signal into the MiniMe P63. Today, all signal processors (5.1/6.1 and more advanced ones) come equipped with built-in pre-amplifier outputs (RCA) that include a subwoofer output. Generally, the SUB PRE OUT is in mono format. Connect the SUB PRE OUT from the processor/receiver to the MiniMe P63 LOW-LEVEL INPUT using a “Y” RCA cable. We strongly recommend that you use the best available RCA connectors and cables. High-quality cables are normally triple shielded and the connectors are gold plated with forceful grasping. When using this connection, the MiniMe P63 only receives bass signals from the source. Therefore, the crossover frequency should be set at the max value.
Low-Level Setup – Dual Sub
For a more realistic sound stage and greater theater experience, we suggest having two (2) subwoofers and running them in stereo.
Using a “Y” RCA cable, connect the SUB PRE OUT 1 of the receiver to the LOW-LEVEL INPUT of the left side MiniMe P63
Using another “Y” RCA cable, connect the SUB PRE OUT 1 of the receiver to the LOW-LEVEL INPUT of the right side MiniMe P63
In case the subwoofers become out of phase with the main front speakers, adjust the phase shift to correct the problem. Note that maximum bass is only achieved when the sub is in phase with the speakers in your system.

Adjusting the Controls

There are two main methods for adjusting the level, crossover frequency, and phase of the Earthquake MiniMe P63 to match a system:

• Method 1 – Typical
  By listening and making adjustments to suit your preference.
• Method 2 – Laboratory
  By measuring the output and adjusting for flat frequency response.

Satisfactory results can be achieved if you make the adjustments based simply on listening. This is Earthquake’s preferred method as it allows the system to be voiced based on what sounds the best, whereas laboratory-flat frequency response can often be clinical and less than exciting.
The following procedures are for those who prefer a more methodical and scientific approach. You will need a test CD with low-frequency warble tones and an SPL meter.
Step 1
Disconnect the subwoofer and run the main speaker with a tone in its passband (80-100Hz). Measure the level.
Step 2
Disconnect the main speaker and reconnect the subwoofer. Set the subwoofer to its highest crossover frequency. Set the VOLUME of the subwoofer to give the same sound pressure level with the same tone you used in Step 1.
Step 3
With both the subwoofer and the main speaker connected, measure the level of the tones at the available frequencies. Because the crossover is set to high, you will have a peaked response. Adjust the crossover FREQ control to get the smoothest response.
Step 4
Use the phase control to make the response even smoother. It has its biggest effect at the crossover frequency. You can iterate between the crossover and the phase controls. Keep your hands off the VOLUME control as it was correctly set in Step 2.
Step 5
Listen to the subwoofer. Resist all temptation to turn up the VOLUME control. Play something with really deep bass to confirm that your subwoofer is working. Use the following charts to record more desirable data from test results.
