Question: In a motorhome, how many watts to the speakers is "enough" for a good quality surround sound experience. Don't need to blow the doors off, but want to be sure I'm not going with too little.
It rather depends on the speakers as their efficiency can vary quite a bit, but generally it's a lot less than many people think. Deep bass (as in subwoofers) generally would need more power to sound good, but most RV speakers don't even try to produce deep bass, so that's a moot point.
Sound loudness is perceived logarithmically, and sound levels measured that way. Doubling the power increases the volume by about three decibels. Most of the time, your speakers would very likely be driven by a good bit less than a single watt on average--but it's the transient peaks that are of more interest, and where the extra power can be useful.
