    • 6.5" rear deck speakers
They are great for the price frl and they perform great. And they also fit in the factory location on a 85 Volvo dl 240 and they sound really clear and don't have any distortion

    • Good speakers. Blew them way to early
Honestly good speakers for stock amp. Blew them up around 3 months in. I also blast heavy hard techno, uptempo, and EDM so that's my fault. Anything else these r awesome

These CT Sounds bio are well crafted with durable surround. This aids the speakers performance. It appears to be boxed well and has mounting and installation accessories. Their is filter located under the tweeter this should limit distortion and improve clarity. Update, these sound phenomenal and was easy to install. ... show more

    • What a bargain!
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. ... show more
