Our take on the BIO-5X7-COX 5x7" Coaxial Car Speakers, Pair

The CT Sounds BIO-5X7-COX is a pair of 5x7-inch 2-way coaxial car speakers rated at 80 W RMS and 160 W max per pair, with a single 4-ohm voice coil. A polypropylene woofer handles the mids and bass, and a silk-dome tweeter sits at the center for the highs. They are meant as a drop-in upgrade for factory speakers and run fine off a stock head unit, though an amp gets more out of them. Against other budget coaxials, the draw is the component-style materials at an entry-level build level.

Best forReplacing worn or blown factory 5x7 speakersShoppers on a tight budget who want a full-range coaxial pairStock head unit or light amp setupsOwners who want silk-dome highs over harsh metal tweeters
Pros
  • Silk-dome tweeter is smoother than common metal-dome budget tweeters
  • Polypropylene woofer with a single 4-ohm coil is easy to drive
  • Runs off a factory head unit, aftermarket unit or multichannel amp
  • 80 W RMS per pair is enough headroom for most factory replacements
  • Sold as a matched pair, so both doors or rear decks get done at once
Cons
  • Only 80 W RMS per pair, so it runs out of steam on high-power amps
  • 5x7 is a less common size than 6x9 or 6.5, limiting vehicle fit
  • No separate crossover, so the tweeter runs off a simple built-in network
  • Few owner reports available, so long-term durability is unproven

What reviewers say

  • 4.8 / 511 ratings

Ratings are strong but thin, with 11 scores averaging 4.8 out of 5. Buyers treat them as a straightforward factory replacement and like the balanced tone for the money. There is not enough feedback to judge long-term reliability.

What people mention
  • Sound qualityPraisedOwners describe a balanced, full sound with tight bass and clear mids for a budget coaxial.
  • TweeterPraisedThe silk-dome tweeter is called crisp and smooth rather than harsh.
  • Power handlingMixed80 W RMS per pair suits head-unit and light amp setups but limits louder amplified builds.
  • FitMixedThe 5x7 size drops into some vehicles directly but needs adapters in others.

Questions and answers

Do these need an amplifier?
No. They run off a factory or aftermarket head unit. An amp gets more volume and control out of them, but it is not required.
What is the power rating?
80 W RMS and 160 W max per pair, with a single 4-ohm voice coil. That suits head-unit power and modest amplifiers.
Will they fit my car?
They fit vehicles with 5x7 or 6x8 openings, often with adapter plates. Check your factory speaker size before buying.
What is in the box?
A matched pair of 5x7-inch 2-way coaxial speakers. Mounting hardware and adapters are not listed.
How do they compare with 6x9 coaxials?
5x7 gives less cone area and usually less bass than a 6x9. They are the better pick when the factory opening is 5x7.
