I've been reading several people whine about Klipsch's decision to discontinue the SWS. I assure you, this was not decided on arbitrarilly: It had nothing to do with sales, production costs, limitations, or anything of that sort.
Fact is, those who now have an SWS plugged-in are at risk.
The FCC refused to pass the unit after a thorough inspection. Thus, Klipsch, for one reason ro another, chose not to re-design the subwoofer as to pass regulations. My guess is that a redesign would mean a loss in performance.
So therefore, since the sub did not pass FCC inspection, if your SWS were ever to catch on fire you would -not- be elligible to collect insurance.
