Speaker Design

Speaker Type
The type of speaker determines the use that the speaker is intended for. Some speakers are manufactured specifically for home use while others are made for professional use.
Multi-Purpose Home Speakers
All-Weather/ Water-Resistant
All-weather and water-resistant speakers are made to withstand the elements. They usually have been treated with a protective coating to shield against all types of weather. From wet to dry, hot to cold, these speakers are prepared. Speakers that are water-resistant are not to be submerged in water.
Professional/ DJ Equipment
This feature designates if the speaker is designed for professional use. Professional products consist of high end PA (Public Address) systems, DJ Equipment, Karaoke equipment, and other uses that require a high end unit.
Indoor/Outdoor Speaker
This designates whether the speaker is intended for indoor use or outdoor use.
Multi-Purpose Speaker
This designates if the speaker can be used for multiple activities. Can be hooked up to anything that uses a 3.5mm headphone jack, such as a CD/MP3 player or a computer.

Speaker Specifications

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.
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.
100 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.
50 watts
1/4" Phone Jack
A 1/4" Phone jack can be used to connect the speakers to the audio source. The jack can usually be found on the terminals. The 1/4" phone jack can be used instead of connecting speaker wires to the terminals. If the output source supports this jack, a lot of time can be saved when setting up and taking down equipment.
3.5mm Stereo Jack
Uses a 3.5mm stereo jack to connect to an audio source. This is the common size found on most CD and Mp3 players, as well as most home computers.
A horn is found on some loudspeakers to increase the efficiency of the driving element. Often found in PA systems, horns are typically used to increase the high sound levels
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".
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.

Speaker Enclosure

Maximum Wall Thickness
This is the maximum depth the wall can be for the speaker to fit perfectly.
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.

Terrific for the money!

September 26, 2011

For the money, this is the best speaker set in the world. It seems impossible to have gotten so good and balanced a sound at the oh, so low price. I know a top record engineer/mixer who checks his mixes on them. He praises them for the solid bass and overall balance of frequencies. The sub-woofer does not have to be turned up much beyond one third.

For the $ this is a good deal.

February 13, 2013

I have owned these speakers for about 4 months now, I am using them as tv entertainment speakers in my small apartment living room, they sound great while watching a Blu-ray movie, fills the room with all the sound I would need. I wish they had a wireless remote with volume up & down, this model has wired control like most PC speakers. Would be a great set for gamer or someone like myself who wants to have an inexpensive option to upgrade tv sound.

The best for the money at any level of audio

April 2, 2012

I'm a pro recording engineer with a number of hits and award winning recordings to my credit. Know that the COBY CSMP80s, when properly placed and set up (the bass control is critical), are good enough for me to use as my main mix speakers!!! At a little over $30, that is phenomenal. I would not have believed it until I heard it. My go-to speakers are JBL LSR28Ps, which are highly accurate. The Coby's are not quite as good, but again, I could mix acceptably on them. The bottom end goes down to 50Hz if they're set up well and not too far from a wall. I've had no trouble with mine since I bought them a year ago. Buy 'em, and smile. I've bought ten sets and have given them to musicians and engineers who needed a second set of mix speakers.

The Coby csmp-80 is a very good stereo/speaker system. The Coby csmp-80 has a well structured box for the subwoofer, and 2 towers for the speakers. The subwoofer is the best for something this small. it has a very good bass response, it plays low notes very well, and high notes are not to bad. The knobs on the back of the subwoofer box are easy to use but sometimes they are hard to find if you are not looking but soon you will get used to were they are. Overall this speaker system is awesome if you want some thing for your computer or just to listen to something I would recommend this speaker system. hope this helped :)

Great speakers, dont be discouraged!

May 27, 2010

These speakers are an amazing value.. Coby is a pretty cheap brand but this is one product they did rite! I have 10+ years of dealing with audio equipment.. and these speakers are still surprising the VALUE they have.

Great sub, good CLEAN bass.
Decently loud.
Good speakers, they seem to pair decently nice with the woofer.

Lacking a little in the mids, but if your no audiophile, you'll be just fine!
Certain high frequencies in the satellites will distort at high volumes.

For the money this speaker set is awesome, yea you could spend 4x as much for something bigger and better, but if all you need is a nice little 2.1 system to listen to some music and watch the occasional movies, these will do it.

worth the price!

September 18, 2010


Cons: States it puts out 100 watts. I don't know exactly cause I have not used a meter to measure it. Sounds like half.
Low in the midrange do to speaker size.

Pros: It was well worth the price and loud and clear enough for a small room.

Bottom line, if u want power. Go buy the Klipsch 2.1. It will cost u another $125 or so but has a real 200 watt sound. I have it on my computer and the coby in da rest room for my mp3.
