Speaker Specifications

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"
Design
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
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
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.
Polypropylene
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.
150 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.
75 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).
130 - 20000 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
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.
2-1/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-3/4" x 4-3/4" 
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.
Yes
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.

Good sound for good price

September 8, 2010

Bought a set to mount on the side of our camper. They are a good size unless you want to really crank them up but for our use they are perfect. Our radio is not very powerful so up to about 3/4 volume they sound great. The rain and sun have had no negative effect on them at all.

Nice little speakers

August 15, 2010

I installed these on my motorcycle, and they sounded good, but do have their limits. At highway speeds, you could no longer hear the speakers, which makes them an ok set for quiet bikes and in city driving, but not good if you have modified pipes or do highway driving. Overall they have good range with some acceptable highs and midrange....they lack in bass, but I guess you wouldn't be bumping on a bike...lmao.

Great Value!

November 2, 2009

Features: I purchased these speakers as a cheap replacement. I was amazed at the quality but two things stood out right away. First the wattage rating is an amazing 150W. This is rare in a set of speakers this small especially if you have a decent head unit which pushes 52W per channel. Other speakers were only rated to 40 and we all know what happens when you crack the sound up with those! Secondly, the frequency response was a very wide range thanks to the true dual coil. 120Hz won't obviously give you that pounding base, but it was 40 Hz lower than other 5 inch speakers. Quality: The construction is premium and I like the reinforced housing. Other speakers just have the magnet housing attached to the speaker plane. These had struts that backed up the attachment and will obviously reduce the chance for cracks riding through bumpy water. All wiring was tinned and was stainless. No exposed copper to corrode. The wiring was plastic coated and was seamless. A true "marine" speaker instead of a name change. Installation: I have a 2001 Baylier 1950 Classic Capri and both of the factory speakers were cracked from normal wear. I had to bring the factory mounting hole out just a litte bit (1/8 inch). I used a rotary tool and a scouring blade and it was perfect. The included screws were more than long enough to penetrate the padding, speakers and set into the wood backing. My only complaint is that the spade connectors on the speakers are just a touch smaller than the wider factory clips. I had to crimp new ends on the boat wiring, but that was the only problem I had. I would definitely recommend these speakers to someone (especially a Bayliner owner) looking to replace or even upgrade their factory speakers.

I purchased this amp for my atv and im running 8 BOSS 5 1/4" coaxials with it. The amp has never cut out and seems to be very efficient. It has plenty of power. My bike sounds just as good as $1000.00+ systems that ive heard.

Decent speakers for the money

April 7, 2009

These speakers are descent for the money. I installed in a 1998 Bayliner Capri and I had to cut the hole slightly larger than the original speaker hole. they just fit in the padded area so they worked out. It will take you a little time to trim the hold properly, but these will work.
