For example, I have a closed back 2x12 and the same exact speakers and everything sound very different in my other 2x12 and I dislike it but love the other....with the same EXACT set of speakers.
Also not bad here..... You can also order them unloaded if you already have speakers. Different 112 sizes too or you can ask for a specific dimension or color as well as they are made to order.
Late to the party, but I've noticed timber differences based on the enclosure. Things like smaller cabs sounding pokier and more broken up vs a larger cab, and changes from close-back to ported affecting clarity, smoothness, and overall frequency balance (not just the low-end either). I can not give a well-reasoned explanation for this stuff yet, it's just what I've perceived.
