    I am sorry to say "concrete" is the worst thing to use when building a speaker enclosure as the acoustical qualities are horrid,maybe if you open it up and line the entire enclosure with a thick rubber it may work but if i were you i would use a particle board box.

    Great instructable. Thanks for posting it but unlike a couple f previous post I just don't get using concrete as the primary enclosure structure. I guess that may be due in part to my love of working with exotic hardwoods. To me, concrete just isn't aesthetically pleasing.

    Concrete looks great in this project. Its main advantage here is weight. Big weight is good for loudspeaker! ) I think it will sound better, if you separate speakers from each other to get stereo effect . )
