Sounds like a recipe for disaster to me. People often make the mistake that small speakers are suitable for low powered amps but often the reverse is the case and the small cabinets make them inefficient and hard to drive. Something like the small Q-Acoustics 2010s sound like a completely different beast depending on what they’re on the end of. Small speakers in a large room are a compromise as it is, add a puny amp and I think a re-think would be in order.
