Yes, the weight may be a problem for you. You did say in another thread that the weight difference between a 10 and 12 inch speaker was substantial enough for you to stick with a 10, so maybe Oak wouldn't be the first on the list. I've only played one cab made out of a solid hardwood and that was a Krank Revolution cab made out of Poplar, which is lighter than Oak by a lot. It did sound really great. Just going by the properties of Oak, I think the same cab would have more "dead" sound to it. Oak is very stiff and very heavy, two properties that, IMO, would reduce cab resonance a whole lot. Thickness of the stock, construction, open/partial/closed back, sealed/ported, the volume of the box, the speaker .... these are things that are as important as the choice of lumber IMO.
