Speaker Specifications

This is the manufacturer product line of speakers.
Power (Rockford Fosgate)
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 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.
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.
250 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.
125 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".
87.5 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).
40 - 30000 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 or millimeters, required to contain the speaker.
5-11/16" x 5-11/16" 
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.

best price online

May 9, 2013

i bought these when they first came out for 499.00 from a local dealer. wish i had found them here first.
I am running them with a punch 300 which is rated at 100x2. it is a great set up. This is all i am running for mids and hi's. Gain is only 1/4 of the way up and the sound is absolutely amazing. Can listen to them all day at full volume. matches up well with my 1 10" cvx which is powered by a t500bdcp.

only complaint is that it came without any directions. the crossovers were different than the ones i had owned previously with my t2's so i was a little confused at first.

overall this is probably the best deal for the price for high end type mids/hi's. cant go wrong with this purchase. they are going into my next install as well.

Honolulu, HI

Loud, crisp and clear.

December 11, 2012

Title says it all, best sound quality speaker I've heard.
Two pairs running off a Rockford 600-4, and it super loud!
Design of speaker is a plus also, I've been commented about how far it's been heard without my sub on (blown) and it had the ability to drown out others system off the speakers alone.
Impressive prices from sonic as well better deal then I could get locally, just hope they continue to sell t3s continually!!

Swanton, MD

Overpriced, mediocre performance

March 5, 2014

Average set of components overall. Way over priced and the tweeters are way to harsh.

However, the build quality is superb and the packaging these came in was fantastic!! I have never received so many installation accessories and tweeter mounting options than I did with this set. The woofers provide an excellent low-mid range, but the tweeters leave much to desired. The crossovers also lack many options which are normally found above the $500 dollar price range, but they look damn fancy!

Based off of the price I would have to recommend customers away from this product, but if you can find a set for $300-400 they're worth it. After I returned these I went with the ID XS-65s and have been much happier.

Be careful

February 23, 2012

I bought these a couple weeks ago and am just now installing them because they are too deep for my acura tl. I had to pay another 200 for some custom kick panels that u can install your speakers into. I'm sure later today when I install them along with my Rockford t4-800 amp and my 2 L7 12's with the Rockford t-1500 I will be in dreamland but just wanted to let people know there may be additional expense that comes along with these.

unreal SQ with a serious punch

November 23, 2013

I bought these as a step up from my RF T2's. I have two pairs in my front doors and they are beyond ravishing. These speakers will make your music come alive in ways you cant even imagine yet. I have heard the utopias and the legatias. these speakers for 1/2-1/4 of the price of the focal or hybrid audios are right up close in the sound quality. the tweeters are bright and vibrant (although putting the trim rings on requires and ungodly sense of patience) and the woofers are insanely loud and punch with authority comparing to some 8"-10" Mid range drivers. I Highly recommend these to any serious audiophile. you WILL NOT regret this purchase
