CS Series Car Speakers

Cadence speakers have always been known to produce high quality music, and the CS Series is no exception. The 1" mylar dome tweeters produce an incredibly accurate presence of highs that blends soothingly with the mid-woofers. The injection molded polypropylene cone provides incredible sound damping and a very natural sound. The included rubber magnet cover will provide added protection from the elements which increases the overall lifetime of the speaker. The speaker surround is made from butyl rubber to provide maximum sensitivity and minimal decomposition of the suspension. For a high quality speaker that will not give you listening fatigue, go with Cadence and you will not regret your purchase.

Deep rich sound, but low quality construction

Cheap speakers, and you get slightly more than you pay for. The sound is impressive honestly, but the quality of the speakers are low. The tweeter component actually came loose from the rest of the speaker creating a huge rattle after 2 weeks of normal use. I would not buy these again personally, but if you are on a budget, you could do worse.

Great Value

These speakers replaced the mid drivers in the doors of my 2012 Kia Rondo. The speakers produce surprising bass and the mids and highs are clear and well defined. I also bought a Clarion XC1410 amp from sonicelectronix to power them. I couldn't be happier with my system - and all on a very low budget.

Pros: Affordable, sound great.
Cons: None at the moment.
