I have quite a few 10" speakers lying around that I'd like to put to use in an open-back extension cab. I am considering purchasing a cabinet for this purpose and am leaning toward a combo amplifier cabinet rather than a proper extension cabinet. My reasoning is that even though I am not currently looking to buy another amp, it would allow me the option of purchasing a corresponding chassis-only amp to install. I don't see any downside to this other than the cabinet without the chassis may look a little funny. The cabinet would be for home use, not on stage, FWIW. Is there something I am neglecting to consider?
