Re: Line 6 cabinets
Unless it's going to be for home use only, I would save up for a cabinet constructed of plywood, not MDF. Or, find a good deal, used. MDF is heavy and doesn't hold up nearly as well to abuse or the elements.
I have an MDF 4x12 that I got for dirt cheap. It needed work and it now has a plywood baffle and back board. But that cabinet sounds huge. It's loaded with WGS speakers. MDF doesn't necessarily sound bad, but again, it's heavy and no very road worthy. And usually, they don't come with the best speakers. Best bet if the budget is tight, look used for a plywood cab already loaded with nice speakers. Even if you don't plan on gigging with the cabinet, you'll be out more money buying a cheap MDF cab if you end up having to replace crappy speakers. Again, the cheap cabs often don't come with great speakers.
