Also there is a somewhat standard practice in my tier of pro audio to always use amps that can deliver at least the full power (or more) of the speaker even if only planning to use 1/4 of it. This covers us for the unwanted massive transient spikes that can sometimes occur in live performances (knocking a mic or loose connections for example) as an over powered amp/underpowered speaker is a far safer combo than underpowered amp/overpowered speaker due to risk of amp clipping and sending DC voltage to driver
Its hard for me to not default to the same practive when dealing with smaller projects
