I saw you want to pair a couple of 210’s together but you didn’t mention you already had the cabs so this is my suggestion.
Go to
Avatar Speakers and checkout the Genz Benz/Avatar cab combo packages.
Get a pair of Avatar NEO B210’s with a Genz Benz head. The head will be discounted with the purchase of any cab(s).
The Shuttle 6.0 head (600w @ 4 ohms) would be plenty enough to drive two B210 NEO’s, but you can get the 9.0 or the Streamliner for more $$$.
For small gigs, one cabinet will suffice. The cabs are solid and they use good Eminence speakers with high XMAX (excursion).
If you do have the cabs picked out already, consider the Carvin B2000 head. For around 600 bucks, it has brutal power, pre-amp tube and all pro features. It warms up very nicely. It's just a great head by any measure.
