Subwoofer Specifications

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.
360 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.
720 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.
Santoprene 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".
88 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).
20 - 300 Hz
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.
17.9 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

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.
14-3/8"
Width
The width of the item from left to right (side-to-side) measured in inches.
17-5/8"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
15"
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
17-5/8"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
3/4"
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.

Spring posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
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.

quite the surprise

March 26, 2015

When I decide I want to purchase an item, I do lots and lots of research before deciding what to get. I did the same for my newest audio system. I'll admit, I second guessed my decision many time before actually ordering this subwoofer but I am so glad I went with my decision. the box is 5/8", built like a monster and looks awesome! now on to the more important part- the sound quality. I have only continued to be impressed with how well this subwoofer handles low frequencies! it might only be hitting 88 dB, which is lower than some other 12" subs, but its hitting 88 dB on frequencies I didnt even know were there.On top of that, even though its in a ported box, the sound quality is better than several sealed subwoofers I've had in the past. All in all for the price you will not find a better loaded subwoofer. I highly recommend this if you enjoy annoying people at stop lights and want a cheap loaded enclosure. Once again, polk audio fails to disappoint!

Good Sounding Compact Sub!

April 30, 2015

I needed more space in my trunk so I decided to downgrade to get more space but I didn't want to sacrifice and lose all my bass. To be honest I didn't expect much coming from 2 12s before. However, I was pleasantly surprised at the good punch this 1 12 supplied and more so the sound quality of this sub. I would definitely recommend this sub to anyone looking for a reasonable compact sub that will provide sufficient bump on a daily basis.

Very clean

August 7, 2015

This sub has great sound and it hits really low frequencies with relatively low power needed to run it. 150-250 watts is plenty. The box is really nice too. I would buy another one.

JUNK

March 31, 2016

Stay away - this is junk. I powered this with a 300 watt amp. It lasted approx 4 hours of play time & then 1 of the voice coils shorted out & caused a "dead short" which took out my amp.

I have been installing "systems" since the 90's and never had this happen before. I should have known the price was "too good".

Between this and JBL.......
Hooked up in the garage and have to watch the volume.
I liked the looks a bit better and spec's also, have done sound in local clubs and gigging for over 12 + yrs as far as pro always loved JBL but what swayed me the most was what I said above.Have Polk for my surround system and very happy. Hooked up to a crunch 2000.1 and I was very happy with the sound and build not bling'y like the other.
and a thanks to Sonic shipping was right on time !

The DXi1201 is 17" wide and will fit right behind the drivers seat about 6" from my butt, with about 500 Wrms should have plenty of bass up front and all of the available cargo space available to use for cargo..
The 4 people that bought it before me had nothing but nice things to say about the SQ and it's made by Polk Audio so you probably can't go wrong..

can this be powered by the boss 1500 watt monoblock ?
erin t on Jan 20, 2016
Best Answer: It will run fine with a 1500 watt boss amp. Just pay attention to the RMS wattage and set your gain properly (never above half), using an SMD DD-1 is the best way.. I have this sub in my wife's car With a Kicker CX600 and its plenty loud at 325w RMS.

I got the Infinity Reference X REF-5002ix5-1/4" 2-Way Reference X Series Coaxial Car Speakers (peak 135 watts, RMS 45 wats at 3 ohms, JBL GTO928 6-Inch x 9-Inch 2-Way Loudspeakers (peak 300 watts, RMS 100 watts at 2 ohms), and interested in getting this subwoofer. So which amplifier do I need for this set up? Also, does this subwoofer fits for 1997 Toyota Camry 4 door sedan's trunk? Would the set up works or I need all at the same ohms for the speakers with the amp?
brandon v on Apr 5, 2016
Best Answer: Hi Brandon,

-Infinity Reference X REF-5002ix
-JBL GTO928
-Polk Audio DXi1201
(you gave us waay too much info, so I'm putting this here to it is easier to follow =P )

-So which amplifier do I need for this set up?

There isn't any One option, so here are a couple to choose from.

http://www.sonicelectronix.com/item_64246_Kicker-CX600.5-12CX600.5.html

http://www.sonicelectronix.com/item_67754_Rockford-Fosgate-Prime-R600X5.html

-Also, does this subwoofer fits for 1997 Toyota Camry 4 door sedan's trunk?

Unfortunately, we don't have a database of vehicle trunk space, so we can't answer this.

-Would the set up works or I need all at the same ohms for the speakers with the amp?

It'll work.

Hey, what are the main differences between this sub setup and the Polk Audio dB1212 setup?
Bryan C on Sep 21, 2014
Best Answer: Hello Bryan,

According to the specs found on the manufacture's site, the main differences , besides the cosmetics, are that the Polk Audio DB1212 is far more efficient - at 97 dB vs 88 dB - and allows for a tighter frequency range - at 26-200 Hz vs 20Hz-300Hz .
