## Description

The CT Sounds BIO-5-25- 5.25” 2-way coaxial car speakers are the perfect upgrade for your factory car speakers. Sold as a pair, the Bio 5.25 inch car coaxial speakers are extremely versatile and can run off your factory head unit, an aftermarket head unit, or a multichannel amplifier. Named after the biosphere, the lowest layer of earth’s atmosphere, these full-range 5 ¼ car audio speakers come closer to earth delivering a nicely balanced tonal range at a price that won’t send you into space. The silk-dome tweeter combined with the polypropylene woofer delivers sound that is rich and full with tight bass and mids. Don’t just hear sound. Travel to the future and experience it. CT Sounds car 5.25 inch speakers will take you on a sonic journey of rich mid-tones and crisp highs.

Review: Given the price, honestly I wasn't expecting much but you never wanna put expensive speakers in a truck. I added these to my beater 2000 International rollback. Coupled with the dirt cheap $25 Dual Wal-Mart stereo as reviewed by Big D - Old School Stereo (YT), I'm absolutely blown away by how good this combination sounds. Plays Steely Dan crisp & clear turned all the way up to volume level 35 (max is 40) while not getting muddy at all with the bass set at level 5. Any other cheap setup like this never cuts thru the noise of a truck but this sure does. S/N ratio must be a little better than what they rate them at. Speakers appear to be built very well with nice quality textured powdercoat frames & I expect they will last as long as I care for them to. I'll be buying more sets for my other trucks. Super impressive!
Review: I feel like I could have gotten better for the price. Just make sure you install them right or they will not sound good at all. The highs are good but hardly any mid bass and I understand a 5.25 won't produce a lot of bass but still not good.

### ⭐⭐⭐⭐⭐ Review
*by C***S on 25 December 2024*

I was surprised by these speakers, using both of them as center speakers on a custom box on a large home theater system 20+ speakers system. Ive had them almost maxed out after breakin period and zero distortion, nice clean sound. Can't say much about bass as I'm using them as centers and the system has enough bass to shake the house down but they are nice and loud to be able to keep up with the rest of the system playing music and movies. I would buy them again. For a car system i couldn't tell you but as I'm using them they are awesome.
