Honestly these work perfect if you have good speakers and no amp, with subs. That way your speakers are louder and the subs take care of the bass. Although the bass at times does sound muddy.

not a set

So the website doesn't really explain if this is for 1 speaker or for a set. It is just for one.

The product works great, just make sure you order two.
