Mesa cabs are very well constructed, but also very heavy.
Their switchable crossover is also very versatile for tone shaping.
Out of all the Mesa big(ger) cabs, I like the 215 the best. To my ear, it has the perfect balance of mid detail, punch, and bottom.
The 412 has a little more bottom and less mid. It also handles more power than the 215.
