I want to do some ground plane measurements of some speakers I have, I live on top of a hypermarket so the parking lot Sunday morning would be perfect for that.
However delivering power to even a handheld class D amplifier seems like mission impossible without buying an external generator. I was wondering if there are amplifiers out there (to deliver 1 to 5 W of power only) that i can use with a mobile phone power bank?
There are really no requirements other than a decently behaving frequency response vs impedance. In other words it just has to work and not pollute the measurements much.
