Feel the Earth Move and Quake with Tremor-X Subwoofers

The TREMOR-X154 15" single 4 ohm subwoofer by Earthquake Sound is the kind of woofer no car audio enthusiast should be without. Its pressed pulp fiber cone and high-roll rubber surround provide sturdiness, rigidity, and increased performance, while the Turbine Cooled Transducer technology keeps the voice coil at lower temperatures for longer and louder bass reproduction. The woofer also features an anti-wobble cone construction and reinforced dust cap construction for improved linear movement, thus creating a nice steady bass at any volume level. Its spring-loaded terminals offer a quick and simple installation while the thick density magnets offer better efficiency. This Tremor-X series subwoofer has everything you need from a subwoofer and it's even marine compatible for installation on boats, not many other woofers can say that. In today's economy this woofer is the best bang for your buck.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Tremor-X (Earthquake)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
15"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
1500 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
750 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
86.3 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
30.48 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Bandpass
Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.51 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.51 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
3.00 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
3.00 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
6-3/8"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
13-3/4"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
28.815 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
138.75 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
0.667
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
0.890
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
3.700 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.
2.657

THE 15inch EARTHQUAKE TREMOR SUBS I PURCHASED FROM SONIC ELECTRONIXS ARE THE BEST SUBWOOFERS EVER, PERFECT DEEP BASS RESPONSE , 700watt RMS PER SUB , MAKE SURE YOU HAVE A MATCHING AMP TO GO WITH THEM. THESE WERE INSTALLED IN A 2006 TOYOTA TUNDRA DOUBLE CAB, IT SHOOK THE GROUND!! MAKE SURE YOU INSTALL THESE SUBS IN A PORTED BOX NOT SEALED. THESE BAD BOYS NEED TO BREATHE!! PERFECT SOUND AND SONIC ELECTRONIX IS THE PLACE TO GET THEM !!!

These things pound

April 29, 2014

I went ahead and bought 4 of these earthquake tremor x154 and built a huge 20 cube box in my Yukon denali. The box is port tuned to about 40hz and they freaking hit. The body and windows look like jello when they're pounding blurrs my vision with every bass note. People say 15s are sloppy and not accurate but these are clean, crisp and tight. I played some heavy metat with some double bass pedal and they pick up every beat. They have the xmax of 300-500 $ subs, but require way lower power consumption and theyre only running 90$ right now here on sonicelectronix.com. And earthquake gives them a 5 year warranty so there's no reason not to buy these. I will and have already recommended these subs to my friends that want a pounding system. I stand by my review and this product its a definite good buy.

For the Price, Well Worth It

July 31, 2013

First id like to state that the stated RMS handling is not true. Its shown on sonic as 750 watts, while in reality it is only 450 watts(as stated on the magnet of the woofer itself). Its a tad disappointing to see the false ad but it does not mean it is not loud. Its built very solid and can take some power and beatings. Currently I have 4 of these purchased, but only 2 loaded in my car(until i can afford to finish my wall), the two loaded in my car are being powered on 200 watts each( break in period till my amp ships here in a couple days), even on low power it murders the lows and can go as low as 16 hz so far in a 28 fb custom made box (not really audible in sense of a note, but it definitely tickles your colon). The pamphlet that came with the woofer that had the information on the woofer was weak though, came as a photocopied page that was actually fuzzy and difficult to read and didn't actually have a lot of information in it. Sonic was fast on the shipping and has earned my trust fully as an online vendor for all my audio needs. 4 out 5 for false advertising and sketchy looking instruction manual. Still recommended for those who want loud, low, and affordable, good brand.

Very good bang for your buck.

May 16, 2013

I have never really heard of earthquake audio, but reading the specs on the speaker, specifically BL and Xmax, and reading other reviews I convinced myself it was worth a try. I am glad I did, this single 15" receiving a nominal 400W RMS com in a custom designed vented enclosure tuned to Fb of 28hz completely obliterates the two 15's I had prior(power acoustik junk...). I would highly recommend earthquake audio(at least their subwoofers thus far) to anyone looking for good SPL and SQ on a small budget.

Great Sub

December 19, 2011

I got this sub a week ago and I gotta say that I was extremely impressed with it. I owned several brands such as JBL, Fosgate, Orion, MTX, Kicker, and the list goes on and on. This sub by far dworfs all of them. I'd recommend this sub to anyone and Earthquake Sound has become my number one brand as of late!!!

Best sub ever!!

December 12, 2011

All i can say is i change systems alot. Ive had all the name brands except re audio and earthquake. i now am hooked on earthquake. Great SQ and awesome SPL good for all music so far only owned a couple of days. In a sealed box with a fosgate p500-2 still in the break in period so i cant wait til its broken in. Just moved from 2 kicker cvr 2012 12 dual 4 ohm vented box to 1 fifteen and would do it again. Thought 15's were sloppy but very accurate. Good buy highly reccomend to any one.

Awesome Sub!!

December 12, 2011

I just got this sub today and OMG. I owned kicker Fosgate JL even bought L7's this sub ya i said it 1 sub beats them all for all music so far. I was very skeptical about a 15. 12's sounded better and tighter not this thing at any volume it sounds good even stressing the hell out of it. I am powering it with a rockford P500-2 bridged low gain for the break in period but still sounds great. Sooo buy one already.

what size magnet?
chad t on Aug 2, 2014
Best Answer: Unfortunately we were not able to find any of this information on any of our databases. All of our research came out to advising us that it had a "hick high density magnet". We have looked on Earthquakes website as well and they had no specifications on the magnet.
