I took the woofer out of the cabinet of my vintage speaker, and the magnet is pretty small, the speakers are rated at 40 watts. I have them hooked up to a A/V receiver, and I dont turn them up too high because I am afraid of blowing them, I think I need a better A/V receiver to "open them up". I played them on an old generic10 watt stereo receiver and they sounded more dynamic..
