What kind of budget do you have? The Barefaced 210S is small, light (31lbs), really loud and has response from 30 Hz to 6kHz (no tweeter). They are made to order in the UK and then shipped to you overnight, shipping is included in the price which is approx. $849 US dollars. The cabinet has switchable ohmage, you can set it to either 4 ohms for single cabinet usage or 12 ohms if you decide to add one or two more later. You can run 100-500 watts into it safely, more if you play clean.
The newer Mesa Boogie Subway cabinets are light and loud, too, but also pricey. You would be looking at a 12" or 15" speaker, though, not sure if they have a 2x10 option
Where do you live? I am most likely going to be selling an Eden 210XST cabinet soon, cab is in the SF Bay Area. Nice sounding cabinet and easy to move size but 59lbs so not exactly light.
The Schoeder cabinets are nice, too, lots of choices out there.
