Description


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!

Great Speakers

Great Speakers. Good sound for small speaker. Very sensitive and loud. Excellent if you are using a head unit amp.

Good Speaker for use without amp

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.

Great Speakers

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.
