Hola Gary...we have to think that the CLXs, as it is a model that needs a sub(s). On the other hand, the value 56Hz, it is just a merely figured number, because you still have 40Hz info at your CLXs. If you play with the back wall, you even can get outstanding deeper bass notes. But, we must think that the CLXs are designed in mind to have one or two subs, as a part of the whole speaker. You can buy the CLXs alone, but the truth is that they do lack the organ bass notes, and these bass notes are only archived with a sub(s). I have musician(s) friend(s) that had said to me, that they do prefer the CLXs without the sub, unless you are going to listen big orchestra heavy bass content or instruments that have very strong deep notes, like a big drum or similar. My liking is to have the stage wide, with the sense of good 3D, and clean...too much bass energy messes with the stage and makes it to have the bass player next to your seat, and not at the stage. Because our ears are not too good for bass notes, we usually use more energy bass of what the instrument(s) can produce. Dynamics are other thing. As I always say, sound it is a matter of liking. And what I do like, not necessary must be your liking. I do respect all the member(s) who like this bass energy of course. It is our privilege to play our system the way that we like it. And yes, we are fortunate to have very dedicated members with outstanding knowledge and great ears, and always are sharing it with us. People, trust your ears and try to listen unplugged musical instruments on the stage...and you will realize that we still are in dippers regarding sound quality. The good think, we are getting closer every day. Regards from Costa Rica!
