    CT Bio 12”

    I haven’t installed it yet…although, i do have an 10” Bio Sub on a ported box and it sounds really good. I’m glad I made this purchase and will install it on a 12” sealed box (with Polyfil).

    Go CT Sounds!

    This thing is awesome so far for my room setup!

    I am loving this little 12 so far, it sounds amazing in my room and am planning on buying more in the near future for a bigger build! CT Sounds has outdone themselves on their lower level subwoofer.

    Amazing sound but sub blew

    after around a month of having this speaker it sounds amazing but the sub blew, i know you can’t expect too much especially with how good of a price it was so when you make this purchase make sure to get a warranty

    Bio 12’s

    For the money you can’t beat the price on these subs. They sound great and good low end from a entry level sub. They are well built. I have the Meso 10’s in my 4Runner and OMG they are Amazing and will knock your head off. I have the 6.5 Mids with 2 bio 12’s on a CT sound 1000 in 4 ohm in standard cab Chevy.
