Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Reference (Infinity)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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 ohms
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.
300 watts
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

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 giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
300 watts
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.
1200 watts
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

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.
1200 watts
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.
Butyl Rubber
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".
94 dB
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).
33 - 300 Hz
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

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Hatchback Style, Angled Back
Height
The height of the item, measured from top to bottom, in inches.
16-5/16"
Width
The width of the item from left to right (side-to-side) measured in inches.
21-1/16"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
17-1/8"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
1
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Binding posts
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

great for the price

November 12, 2008

I have 2 of these in a custom slot port box. And let me just say WOW. These subs for the price pound. I like insanely loud music and on some songs i have to turn it down. They are much louder than my friends kicker comps. So if your looking a cheap but great performing sub. Buy these.

Great Value - Hits Hard

January 18, 2012

I paired this with the Infinity Reference 1300a 300-Watt Amplifier and let me tell you this thing hits hard. Don't let the price fool you, now it's not going to win any bass competitions but if you are looking for a quality sub in a quality enclosure to add some boom to your system, don't look any further you have found what you are looking for!

Very nice, clean base.

October 12, 2015

I put this sub in a $2500 set up with Focal Krx2's and everything sounds great. The base is tight, and clean. It even hangs well with the hip hop tunes, and rattles the car pretty good. The girlfriend likes how it looks too. Highly recommend if you are looking for quality base at a good price.

94dB sensitivity=amazing efficiency!

October 12, 2015

I purchased the Infinity 1220se to efficiently use the 300W coming from my new Rockford Fosgate PBR300X1. I had been using an old 12" Sony Xplod I had purchased in the mid 2000's. The Infinity is rated at 94 dB of sensitivity compared to the Sony's 87 dB so I hoped I there would be an audible increase in sound output. Knowing that the dB scale is logarithmic every 3 dB increase in sensitivity is the same as doubling the power of the amplifier so going from 87dB to 94 dB should make my amp sound like a 1200W amplifier. I took this with a grain of salt knowing that manufacturers measure specifications a little differently and use tricks to "puff up" their numbers.

I received my Infinity 1220se and couldn't believe the size of the shipping box and immediately thought, "This is ridiculously huge and is going right back to Amazon!" I struggled to remove the 50# behemoth from its sturdy shipping box and quickly squeezed it in the modestly sized trunk of my 2014 Volvo S60 to hook it up. What I heard next was ASTOUNDING!! The Sony struggled to fill my car with bass while the Infinity easily filled my ENTIRE GARAGE with deep, rich, soul stirring bass. The garage door rattled and my dog ran for cover. My friends and I still can't believe that all this bass is created from only 300W. A friend hooked it up to his subwoofer amplifier with the same improvement in sound output and quality. To top it off, despite being ported, it still has tight, accurate bass. Needless to say I'm keeping my new subwoofer!

Great sub, great value

June 15, 2016

I have had the sub in my suv for about a month now. It is running on a class d Kenwood 600 watt amp and is amazing. I listen to a wide range of music and it performs well in every type. Highly recommend for anyone wanting to get an easy "bag" for your buck.
