Hmmm....that seems odd. I haven;t looked inside any of these boxes sold by them. However, their site says the following: "Best of all, the music doesn't pass through any inductors (coils), resistors, or capacitors. A crossover is a necessary evil in all other speaker systems. With Lowthers, there is no crossover to deal with." in the technical discussion page. This indicates that they are NOT using any EQ. Guess the best thing is to open the box & check! -akhilesh
