just read up on the PG site and the Xenons are discontinued, and so goes the XeLoad with the flexiable 1-4ohm stability with similar output, suprised they are going this way, seems as if the Xenon was the step between the Titanium and the Tantrum, and now they are dropping it, so the new Rsd line is taking the place of the Xenon and none are ratted to be 1 ohm stable, what is going on, PG has always been a company with a top end line to aspire to have, now I am not so sure and this goes for the subs and components too, are they down grading to stay afloat and jumping on the F&F bandwagon?
