What are the loudest and best quality, battery powered, portable speakers, for a party, for under £100?
Loudest (High RMS), best quality, battery powered, portable speakers for under £100.
High RMS does not mean loudest. The power rating of a speaker is the level of power a speaker can take before it distorts or takes on damage. Sensitivity is what tells you how efficient a speaker is at converting power into sound. More power means louder, if all else is equal (sensitivity), but power is hard to come by when you're using batteries. Generally speaking, I'd say that there is no such thing as a loud battery-powered speaker, unless you're using car batteries (or deep cycle marine batteries) to power car audio speakers. In low power applications speakers that are literally the loudest will have the least bass, so you really can't power a party with AA or D-cell batteries.
