Priced Per Pair

Speaker Specifications

Series
This is the manufacturer product line of speakers.
db (Polk)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
5"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Silk-Polymer Composite
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.
Polymer/Mica Composite
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
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.
135 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.
45 watts
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".
93 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).
65 - 22000 Hz
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
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.

Yes
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.
1-13/16"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
1-15/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4" x 4" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
No
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Big sounds for a great price!

March 10, 2013

Installed this pair of speakers in a Goldwing motorcycle stereo upgrade. After using these speakers now for over 6 months, I don't think you can purchase a better value for waterproof speakers with the clarity and harmonics of the Polk Audio 501's.

Great Buy

September 14, 2011

Bought these for my Honda Goldwing motorcycle to replace the originals. Turns out the ones in the bike had some aftermarket speakers already in it. These sound so much better with better volume than the previous "upgrades." This was a great price on these as well. Would highly recommend them.

The Polk Audio db501 definately exceeded my expectations and offered a significant step up from my factory 4 inch speakers. I can turn up the volume without worry of distortion and they have adequate bass for such small speakers. Good speakers!

I had to replace some blown Nokia speakers. The remaining Nokias sounded tinny. The addition of these two in the back gives depth and clarity to the music. Now, I can hear the locations of the individual instruments. Plan to buy another pair to replace the remaining nokias.

November 16, 2011

I would like to say that these speakers are great. I installed them on my motorcycle, 1999 Honda Valkyrie Interstate. I bought four and I am very pleased with the sound. Had to do just a little modification on each speaker, but I feel that anyone could do it also. I also bought a power amp but have not installed it yet. Waiting for winter. I would recommend these speakers.

Quality Sound!

May 6, 2013

I purchased the Polk Audio db501 speakers 6 months ago and installed them on my 2008 Honda Gold Wing. They are a far superior speaker than stock. The sound is much clearer and less distortion at high volume. I had to shave off a little bit of the metal from both sides so they would fit. A friend did it with a band saw. It's not a big deal but they simply would not fit stock. I would recommend them to anyone wanting to upgrade from the stock speakers. The other speakers on the market are no better than the stock ones.

db501 in GL1800

August 6, 2012

This is the 3rd pair of speakers I have put in the rear of my G1800. They are the best ones I have put in to date. Much improved bass and volume compared to the previous 2 pairs I have tried. All the speakers have been driven off a kenwood 100 watt amp. An added benefit was that no modification was needed to install these little jewels. Previous speakers used were jm audio which were an easy placement but I wasn't satisfied with the sound and Sony exploid which I modified to fit the housing.

Not what I expected

July 22, 2013

I have owned these Polk DB 501 speakers now for 6 months. They did not hold up. Sound is now distorted and no better than the stock speakers I replaced that had been in the Goldwing since 1998. I am getting a fluttering sound on the Base. I would not recommend this product. There is better out there at the same or better price.
