Only complaint is the speaker wire terminal is kind of flimsy, I will buy another pair for another car ### ⭐⭐⭐⭐⭐ Great speakers *by A***R on 21 April 2026* Sound great. Very happy with the speakers. Very good sound, bass is good for the size of them. ### ⭐⭐⭐⭐⭐ What a bargain! *by H***E on 16 September 2017* If you're looking for realistic sound without super high volume capability for a low price, you'll be hard pressed to find a better product than this one. This is my first purchase from CT Sounds, but I doubt it'll be my last. I'm running these from a Sony MEX-XB100BT head unit, which pushes 40W RMS per channel, and you do get significant cone breakup when you push them too hard; the 30W per channel power rating sounds about right to me. Bass output isn't great, but they sound really good down to the 80 Hz High Pass Filter I'm running. If you want bass, you should really consider a subwoofer. The speaker terminals are pretty flimsy, but the rest of the construction looks pretty good, and I imagine they'll last a long time as long as you don't thrash them. These are great for rear fill or for an upgrade over stock speakers, and if you want clarity for talk or for music, they're a fantastic bargain. ## Frequently Bought Together - CT Sounds BIO-6-5-COX 6.5 Inch Coaxial Car Speakers, 200 Watts Max, Pair - CT Sounds BIO-6X9-COX 6x9 Inch Coaxial Car Speakers, 200 Watts Max, Pair - CT Sounds BIO-4X6-COX 4x6 Inch Coaxial Car Speakers, 160 Watts Max, Pair --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/272160760-ct-sounds-bio-6-5-inch-2-way-silk-dome](https://www.desertcart.gr/products/272160760-ct-sounds-bio-6-5-inch-2-way-silk-dome) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-23*
