Priced Per Pair

Speaker Specifications

This is the manufacturer product line of speakers.
Max (Lanzar)
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.
5" x 7"
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.
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.
220 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.
110 watts
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 - 20,000 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.
7-1/4 x 5 
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.

Just Right

February 10, 2012

I bought four of these for our 2007 Ford Focus sedan based on power handling, frequency response and price. The rear speakers would provide rear fill, while the fronts would be amplified and crossed over.

The Lanzars dropped right into the car with no problem. Don't you hate when you buy a universal speaker and it doesn't quite fit?

I wasn't too concerned with bass response from these speakers, since I had a separate subwoofer. Plus I'm not an audiophile so who knows what's excellent. Generally speaking, the Lanzars were sufficient for me. Maybe the dampened doors helped.

I have the front Lanzars powered with 50 watts RMS and crossed over at 80hz. So far they've handled everything I've thrown at them in the 6 months we've had them. They get way too loud before any sign of distortion. I know that wouldn't be the case if they were playing full range, but it's all in how you use them, right?

All in all, we're satisfied. The Lanzars fit the car with no hassle and do everything we ask of them with no drama. On a different setup they may show weaknesses, but in our case... they're just right.

good speakers

September 17, 2013

i have these in 6x9s in my other car so i went with these for my father in laws car. i figured for the price couldn't beat it esp since he doesn't really care much for expensive stuff or a brand name. his factory fords were gone so he asked me to get him some speakers. at first i thought they had sucked compared to the 6x9s. but after i rode in the car again about 2 months later on a 2k mile road trip. they sounds a lot better. great for a stock replacement on a budget. sound is clear bass isn't really there but they produce clean sound especially for the price.. not to shabby

Toms River, NJ

Ehhhh, be careful....

January 7, 2012

I bought these because they had the most 5 star reviews on Sonic's website and they were CHEAP. I just recieved and installed them tuesday 1/3/2012 and immediately took them out and returned them to Sonic's. There is almost NO bass response and the 4 year old MA Audio 5x7's i had in there sounded 10x better.
I also had to return 2 sets of them for replacements before even installing them because the plastic around the speakers was craked and actually fell off in my hand, and wires were burnt and had solder all over them from the factory.
Be Careful and Look at SonicElectronix 40-60$ pairs MUCH better quality. I really couldnt see these lasting more than a month (if you get a pair thats not already broken).

Great speakers

July 4, 2011

This speakers sound great. They are real clear loud and soft. For the price you absolutely cant go wrong. i'd recommend these over lots of expensive speakers and they cost a fraction of the price. couldn't be happier with them.
