i felt the same way until for a while about a 4x12 which is why i dealt with the weight for so long..... its very easy with a good 4x12 to get a killer tone..... BUT..... when i down sized my rig to a vetta combo and a 2x12 basson cab i started to realize i was missing out on a lot..... while the basson is very remincent of my mesa cabs in the past, the open back of the vetta combo added a bigger spectrum of frequencies i was missing out of my 4x12..... so when i got my roadster i started experiementing with different types of 2x12 cabs that were different than my basson.... open backs, 3/4 open backs, and finally i found ported/vented cabs and was blown away..... with the right design and the right speakers you can easily achieve the volume and punch of a 4x12 and get the wider spectrum of tone do to the ports/vents.... plus the bass responce of a ported/vented cab is so killer and that responce is missing in a 4x12 closed back because the speakers get choked..... so like i said before.... a 4x12 is always a great way to go, but there are many many more options that could be a better fit for a person...... plus did i mention many of the 2x12 ported/vented cabs weigh between 35-50 lbs and give you the volume and tone of a 4x12?
