Nearly every compact monoblock we’ve covered this year uses Class D amplification — it’s more efficient, runs cooler, and lets manufacturers shrink the chassis. The BOSS Audio R1100M doesn’t. It’s Class A/B, an older and less efficient topology, in a market where that’s increasingly the exception rather than the rule. This BOSS R1100M review covers what that choice actually costs you, real verified RMS power, and why over 11,000 buyers and 500+ monthly purchases keep choosing it anyway.
