Stereophile measured SPL at one metre. Probably at 1kHz, BTW which is an indicative but hardly final measurement. It is however useful./ Since CURRENT was mentioned, and adding onto Jeffreybehr informative post, the 4ohm nominal indicates the need for twice as much current as in the standard 1W/8ohm/(1kHz) ratings... for 2ohm, four times the current all else being equal.
As such, it seems difficult to achieve 110db (spl) with those speakers UNLESS the drivers are extremely resistent both mechanically and thermally. Or maybe, the 110 db is an indication of in room spl levels, both speakers driven (even then, each speaker would have to stomach nearly 1/2kW rms). Maybe they mean "peak" (1-3ms)? Or, the 80db spl is wrong???
