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.
Indoor / Outdoor 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.
Yes
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.
No
Indoor/Outdoor Speaker
This designates whether the speaker is intended for indoor use or outdoor use.

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.
Dome
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.

Mylar
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.
200 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.
100 watts
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
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).
80 - 18000 Hz

Speaker Enclosure

Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
Paintable Frame
This means that the frame or cabinet of the speaker can be painted to match its surroundings.
No
Height
The height of the item, measured from top to bottom, in inches.
4"
