I just saw this Mike, when did I say that the Monitor Audios wer not SPL capable?
I do think the GS are a bit more robust than the RS but both would make very good HT or music speakers. Back when I compared them (five years ago), I prefered them (MA sliver) vs the Paradigm Studios. The Paradigm Signature's vs the MA Gold's was A very close call with the MA's being less expensive.
If you want big SPL at low cost , check out the JTR Triple8's. They can handle lot's of power and rattle your teeth out.
