Product Type
Subwoofers with a box,
Price Range
Number of Subwoofers
This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
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.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.

    Polk Audio was founded by three people who have "golden ears" for good sound. Mathew Polk, George Klopfer and Sandy Gross joined efforts to create a loudspeaker company that is dedicated to crafting high quality, great sounding loudspeakers for the public. With the creation of The Monitor Series in 1972, the company got their start in a two story house outside of Baltimore, Maryland. In 1974 the Monitor 7 was released and Polk Audio started to become a well know name in the audiophile industry. Since their first successful loudspeaker they have established a reputation of producing quality products. Now, the company holds over 65 patents for new technology in audio design. Music has always been their passion and creating practical audio solutions is their mission.The Polk Audio brand has made resounding waves in the car audio industry. They feature an expertly crafted line of full-range speakers and component speaker systems for premium sound. The Polk subs are a hot seller with their flashy metallic look and loud bass reproduction. Check out their top notch line of car amplifiers, perfectly designed to power your subwoofers.
