Priced Per Complete Component System: 2 midwoofers, 2 tweeters and 2 crossover networks.

Speaker Specifications

This is the manufacturer product line of speakers.
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.
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.
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 Component System
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.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

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.
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.
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.
180 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.
120 watts
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".
89 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).
60 - 20000 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.

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.
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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4.72" x 4.72" 
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
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.
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.

Well built solid components, nice looking crossover box. Going stong 6 months after install, top sq as you would expect from DLS. The highs are top notch, very mellow and not at all tiring. I am powering them from the front channels of HD900/5, 100w rms.

New Ulm, MN

DLS says it all "Super, Natural, Sound"

September 29, 2011

First off I would like to note that the picture displayed is the previous model.

I had these 2 way component speakers in my 05' Legacy LGT running passively off a bridged Memphis MCA3004 pushing 230 RMS to each seperate. As with most DLS speakers, they are very power hungry. I would atleast get 150 RMS/Seperate if not the rated 125 RMS/Seperate. I adjusted my Gains using an Osciliscope. Mid woofers were positioned "On Axis" in sealed, deadened kick panels, and tweeters were mounted in A Pillars "Off axis" at shoulder height. Don't be afraid to run the Mid Woofers "off axis." Every line that DLS has to offer, all the way from the Reference-Scandanavian has had great results with positioning "off axis." As with most soft dome tweeters, it is better to either Mount them up higher, usualy in the sail panels, A pillars, or perhaps up on the dash. They can get a little "bright." Tweeters are definately the strong point in this component set. Correct me if I am wrong but I believe Scanspeak out of Denmark "makes" all DLS tweeters, or atleast there higher end ones. Same thing with Focal, and Alpines F1 series. Mid-bass lacks a little bit, but taste is subjective. These are a "neutral" sounding set of component speakers. I upgraded them from a previous set of Boston Pro's. I couldn't stand the Harshness of Boston's Metal Dome tweeters. I have owned these speakers for about a year now, and have decided to sell them on a website. I have recently upgraded to a set of Seas Excels + Scanspeak tweeters. Also I will note that the crossovers are larger on the DLS UP5i's. The neodyium magnets make for easy installation, practicaly place this mid woofer just about anywhere.

Great component set, don't be afraid to feed them though. Don't evan bother w/ this component set if you plan on running them off a head unit. I am pretty sure most head units internal amplifier only put out 18-20 rms at max, if not less.

Anyways, solid set, has them cheaper than anywhere else. BUT BEWARE! DLS is known for having "fake copies." Especially with there amplifiers, so buy at your own risk. Check DIYMA. I believe there is an amplifier comparison between a genuine DLS amplifier and a Fake/copied DLS amplifier. Theres pictures of the internals/guts on the amplifier.

I only gave the "value" a 2 because you can buy raw drivers much cheaper, and get better results at a much cheaper price. I would actualy give these a 2.75, not quite a 3. I gave them a 4 on the look design because they look a lot more solid, and have a better build vs the previous model (as seen in picture)

Ease Of Use Gets a 4. Magnets are small, very easy to mount these. They are equipped with 5.25" mid woofers so you can mount them in 6 x 9 slots, or 5 x 7 slots, practicaly anywhere. i would have given it a 5, but crossovers are larger.

Features gets a 3 because you can not Bi-amp this set. You can try going active, but why pay for the crossover than if you're not using it.

Durability gets a 2. Maybe I just got unlucky but I had to get them repaired after about a years worth of use. One of the surrounds came up. However, I live in MN, and winters get down to -30, and summers can climb easily into the 100's. If I wouldn't have had my issue with the surround, I would have given them a 3 or 4.

Look design gets a 5. They look a lot more appealing than the previous model. Tweeters are attractive as well as the crossovers. I could care less about this aspect. Why pay for looks? Only thing anyone looking to buy speakers has to worry about is functionality.
