These Precision Power component speakers have a bloodline that no other speakers can claim. Their design is based on the world-famous a/d/s component platform except with an aluminum voice coil for improved heat efficiency. The woofer cone interlaces Kevlar, Mica, and Fiberglass to create a sturdy platform that can reproduce mids and lows with clarity. The silk dome tweeters are not harsh or shrill on the ears, yet can produce enough noise to keep up with the competition. The Precision Power PPI 355CS components come with a monster of a crossover with many different crossover configurations and a Zobel circuit. These speakers are truly the decedents of the world famous a/d/s component platform. Let your ears hear the sound of legacy.

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.

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.
120 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.
60 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 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 - 22,000 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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
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 deal for 6.5 component system

December 18, 2009

I took a chance on these - seemed too good to pass up such a deal. I would highly recommend these. I'm running them at 75W/side with a Polk SR104 sub (xover at 63 Hz) and it's really impressive. In my opinion, these sound far better than anything similar in the $200-$400 range - I honestly think you can put these against $500+ class components. Crossover are a bit big, but decent caps and air core coils take up space so it's justifiable. Tweeter mounting hardware is good. Although cables are included, they are 18 guage - I feel better with 12 and 16 guage. Fit and finish is also impressive - screw terminals for the cables on the midwoofers is great. Overall, this is one of the best component systems I've worked with. Is it as good as the best MB Quart when Quart was actually making audiophile grade speakers? No, but it's one incredible performer and nothing will touch it at this price point.

Amazing speakers at an amazing price!

October 23, 2009

Get them while you can. These speakers are a steal at $140. They are essentially the same speaker as the a/d/s 346cs.

60 watts RMS? I don't think so. These speakers are way underrated with RMS. They like a lot more watts than 60. There are people putting 150 - 200 watts RMS to them and the speakers love it. I'm putting 80 watts RMS to them and I'm thinking about bi-amping them (80 to each mid and each tweeter) or going active. You will probably not be as impressed if you only plan on running 50 - 60 RMS through them.

It is hard to put into words how these sound. It is really unbelievable that you can get so much sound out of this set. Mid-bass is very rich and deep...the highs are fantastic. They sound so clean and natural. I'm hearing stuff in music that I have not heard in my home system (which is very nice).

The crossovers on this set are amazing but are large 8"x4"x2". The feature set for the crossovers is really amazing and unheard of at this price point. The set comes with speaker wire (looks like 18 or 16 gauge). They also come with 5 different mounting options. The tweeter itself can not be taken out of its enclosure so in reality it is bigger than 1". Keep this in mind if you were planning on mounting in your cars 1" factory mount. It probably will not work.

Did I mention these can get very loud...
