You want a premade, major brand cabinet with speakers? Or, an empty cabinet where you can choose your own speakers? What is your budget? Cheap will most likely get you an mdf cabinet with, maybe, with brand name speakers. But you are limited to what they put in the box. MDF cabinet is probably fine if you aren't going to be gigging with it. More money can get you a ply cabinet with, definitely, brand name speakers, but still limited to what's in the box. And that can be from reasonable money to big bucks.
Depending on your budget, maybe look at someone like Avatar speakers. They make all birch ply cabinets. 2x12's in several styles, including a convertible back (open/closed). You can get them loaded, with your choice of speakers, or unloaded. Unloaded cabs start at just over 300, depending on style. Loaded, with Celestion V30's start at $379, again, depending on cab sytle. That's a real good deal for a good, all ply cab loaded with 2 Celestions. I don't work for Avatar. I do have two of their cabinets.

Of course, there are plenty of other options from plenty of different companies.
For inexpensive, empty cabinets, there is Seismic Audio. They are plywood, but a bit thinner, 1/2" ply as opposed to 3/4". Good, budget cabinets, but not as solid or rugged. I think they also sell on ebay, for a bit less than direct from the website.
