Improved Low-Powered Performance

When looking to replace your factory 5-1/4" speakers or upgrade your current speakers to something of better quality, look no further than the S-Series speakers by Boston Acoustics. These speakers will re-produce your music like you have never heard before and your music will sound just as the artist had intended. The Butyl Rubber surround provides increased bass response and added endurance of the speaker. The cone and tweeter materials used to compose these speakers are designed to produce an overall balanced sound that anyone can enjoy. These are a perfect match to almost any factory or aftermarket stereo without the need for an external amplifier. The integrated crossover network separates the frequencies to their corresponding woofers with great accuracy. These performance speakers are the perfect replacement for your stock door speakers!

Speaker Specifications

Series
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.
5-1/4"
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 Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.
35 watts
Sensitivity
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".
92 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 - 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
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.

Yes
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.
1-7/8"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-5/8" x 4-5/8" 
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
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 Speaker for use without amp

April 15, 2011

If you're redoing your car stereo with a new head unit and speakers, or just want to upgrade your stock speakers, without buying an amp these speakers are a perfect choice. They produce fantastic sound from small amounts of power. The bass is clean and the highs are crisp. Great speaker that will surprise you for the cost, if you're not looking to buy an amp. The biggest downfall is that the "covers" don't cover anything.

These were purchased to replace original OEM door speakers in a 1983 Mustang. Fit and installation were perfect. Sound quality is great, especially in an old convertible.
