CT Sounds Bio 1.0 12 Inch Car Subwoofer 4 Ohm

I got this to replace a 20 year old Jensen 12" subwoofer speaker that was blown. This plugged right in and fit perfect! Tested it out tonight and it sounds great, and that blown speaker buzz is gone. The materials feel of a very high quality, and not like the cheap paper cone my Jensen had.....BTW the original Jensen speaker had "China" stamped on it in big letters....lol. Anyway, I am extremely happy with this speaker and it is an excellent replacement for a home theater sound system....it's not just for cars! It is a great speaker, not just for the money...but just impressive all by itself!

The bass is not good. They don’t accept returns of this item. I am buying here again.

Its a good sub for the price but after a while i heard rattling from one speaker

Beautiful looking from the front , weak looking from the back , bought 2 of these and a ported box, played for one day, and put my single pioneer sub back in.... I bet ct makes great other stuff but these were not impressive at all

Great budget subwoofer i have 2 in sealed box running on a CT sounds t300-D its about half way up and the sound quality is great .anyways good deal would recommend them to anyone

The package came on time but was not package very securely. It was just a loose box inside of a bigger box. Although all that seem to work okay. Build a custom box and it sounds okay. Videos of build on YouTube channel (74 midwestbass)

Exactly what I was looking for. Great buy.

Terrible cheaply made product
