Yes, I will be using a sub but I wanted to test it without one so I could get a feel for the range. I was just surprised at where the rolloff occured. I've heard bookshelf speaker with smaller cabinets go deeper (but perhaps less flat).
And I'm ok with this since I will be using a sub. I just want to make sure the speaker is fully functional. I think it is. Curious if any other owners had the same experience as me.
