the box PA 15 ECO MKII

You would expect this speaker to sound fuller and with more bass than the 12 inch, right? After all, why would you bother with a larger speaker in the first place? Wrong, this one has some spike in the mids, sounds thinner and slightly nasal. One should not bother but get the 12 inch, which sounds good, unless they need a solid cabinet for a different 15 inch driver. The build quality and looks are good.
