(*): nei tower la bassa impedenza è un trucchetto indispensabile per "tirar sù" il dato di sensibilità, giocando sul fatto che se si misura con 2,83 Volt si mandano in pratica 2-3 watt al diffusore, e non uno.
Lab Report
We're becoming habituated to Klipsch making enthusiastic claims for its speakers' sensitivity (repeated in online 'reviews'), and the RP-600M fits the mould. Klipsch says it generates 96dB SPL at 1m for 2.83V input – which, if true, would be an outstanding result – but our tests recorded exactly 89dB, averaged for the pair, on pink noise. This is still a good result, but the 7dB gap to Klipsch's specification is a vast one. In part the sensitivity is achieved through the use of low impedance. Despite Klipsch's vague '8 ohms compatible' specification, this is a 4ohm design.
