Wattage is used as a marketing tool. The only reason it's discussed is for headroom and spl (loudness) capabilities. No one ever listens at max volume all the time, so we recommend that you buy based upon how loud you listen and the impedance (Ohms) of your speakers. Having loads of power (watts) is called headroom and just means you aren't distorting the signal at high volumes and potentially damaging the driver. Sent from my Android phone on the HTF App!
