JBL S3-1024
12" (300mm) High-Performance Car Audio Subwoofer

JBL believes sound quality should never be compromised. And Series III subwoofers make sure you don't have to compromise flexibility, either. That's because the high-performance, step-up subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—for your system. Special aero-cooling design in the voice coil boosts power handling as well as reliability. And an oversized voice coil handles more power than common two-inch voice coils. More power, more reliability, more flexibility—and no compromising. When you're ready to step up, Series III is your subwoofer.


Key Features:

    SSI™ (Selectable Smart Impedance)

    Most car audio system designs call for 2- or 4-ohm impedance. Series III subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.

    Aero-cooled voice coil

    The Series III voice coil significantly increases power handling and improves reliability by going with the flow—of air. The woofer's motor channels air pumped by the cone movement past the voice coil, and the voice coil former exposes the coil's inner and outer surfaces to the airflow. This aero-cooling design is unique among aftermarket subwoofers.

    Oversized voice coil

    The three-inch (75mm) voice coil proves you don't have to be a heavyweight to pack a serious punch. It handles more power than conventional two-inch voice coils, yet it's lighter than four-inch voice coils. It strikes the perfect balance between thermal power handling and low mass.

    Premium screw-down terminals

    Power is the lifeblood of any subwoofer. The terminals on the Series III accommodate up to 8-guage wire (8.37mm2 cross section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs. This ensures the subwoofer—and your music—has the power it needs.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

*Infinite-baffle mounting is possible, but the subwoofer's mechanical power handling will be reduced because there will be no volume of air to stiffen the subwoofer's suspension and prevent overexcursion. If you choose infinite-baffle mounting, consider the RMS and peak power-handling ratings to be half of what is listed

Tips for Installing the your subwoofer


Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
500 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.
2 or 4 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
3.0"
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
25 - 175 Hz
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".
92 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.
12.00 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
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Polypropylene
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Nitrile Butadiene Rubber (NBR)
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.

Ported / Vented
Sealed
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.75 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.50 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.
7.00"
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.
11.125"
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.

Hits Hard

November 7, 2016

I purchased this with amp kit and JBL GTX500 amp. I am running a 2 ohms in a sedan and have amp gain only at 40%. This thing hits hard in a 2.4cf ported box, if i turn it up anymore it drowns out my mids and highs..hits just as hard as friends 2 mtx 12s in a sealed box. Good kit and good product

Oh my goodness!! :D

October 27, 2016

I have this JBL S3-1224 wired up at 2 ohms with a Soundstream PN1.650D and have this in a Rockville RSQ12S 0.75 Cu Ft sealed box. I was able to get this whole set with some other things (Like amp wiring kit) at $300.00

Sub - $115 on Sonic Electronix WITH CRAZY DISCOUNT
Amp - $100 on Amazon
Enclosure - $45 on Amazon
Amp wiring kit (NVX XAPK8 without rca) - $33

My friend who has been in car audio for a while talked me into getting a sealed enclosure since he said that ported enclosures can be irritating after a long time. My friend said a sealed box can just about accomplish what a ported box can do if you feed the sub enough power. 500rms is a great amount to work with. He also reminded me that sealed boxes can go lower and sound tighter too.My JBL S3-1224 in a sealed box screams!

Pros:
No complaints and it does what it was designed to do. It's super loud. Can easily overpower my (for now) OEM speakers. The SQ is also there (With help of sealed box)

Cons: Only complaints were the lead wires would slap on the cone, so I had to do some zip ties on that, but other than that. couldn't be happier.

Very Underrated

September 16, 2016

So I've always been a fan of JBL but never really thought of buying their subs but thought I would try this one as a SQ sub and this sub has been absolutely amazing I am putting 600 watts to it and I have a pair of them in a sealed box and I couldn't be happier I like them more than any sub I have owned and heard (work at an audio store working with kicker Polk alpine pioneer and Rockford and at this price point and even those a couple hundred more don't even touch this sub especially as far as quality goes. Would recommend to any and all except those that use dirty power amps and constantly blow subs.

Loud clean sound

September 8, 2016

I bought 2 of these while on sale here at sonicelectronix. I put them in a ported box with about 1.6 cubic ft each. These subs sounds very clean and have great range. They do prefer punchier bass as they get very loud without breaking a sweat. I recently upgraded my amp to a true 500watt rms to each. They still sound clear and do not get too warm at rated rms. I really like the ssl switch. If you want to change your impedance due to adding a sub or wiring down an amp to meet dif loads you can. That alone will save you time and money. We all want to upgrade our bass over time and they allow easy cost effective solution. Only downside is that they are not on sale at the same price. I'm assuming this is due to the popularity to this new product. Thanks sonic

My 2nd new subwoofer

April 24, 2016

first the sub looks nice and looks well built. my first sub was a JLd12d3 @ 2ohms it hit hard in port box, but it blew being under powered. This JBL hits hard also @ 2ohms paired with Apline m-500 @ 2 ohms 500 rms match up sub nicely. been breaking it in, but i can tell it sounds good even before it has been fully broken into. rewired my amp to 8 gauge wire and my sub loves it. its nice that the sub can take 8 gauge wire getting all the power it needs for deep pounding bass. im happy with my purchase hope it lasts me a long time

Fantastic Subwoofer!!!

April 7, 2016

I have this on a Kicker 500w at 4ohms and the bass is awesome! I was a little scare that this wouldn't be enough power to complement my system but it was spot on! The selector thing is pretty cool, but kind of a gimmick I think...I guess if I add another one later it gives me the ability to choose from more amps. idk . Also, less importantly, it looks dam good!! Thanks sonic!!

Michael M on Feb 5, 2016
Best Answer: Hi Michael,

The amplifier is fine. Have your installer set the switch on the driver to 2ohms.
