The last day of the $279.99 deal, is tomorrow. With local taxes applied to the purchase price, our tab was $300.99. Tick-tock.
As to the broken grills, based on what others have had to post, a call to Klipsch customer service will reward you with a replacement grill.
As to the loose tube issue, simply sticking your hand in the vent opening and pulling on the tube, moves the loose porting tube back into place and if need be, simply remove the driver and glue that puppy into place.
Despite these minor inconveniences, the RW-12d is the Top Dog of this price point. The box is huge as the sub is double boxed, a factory box, inside a larger shipping box, supported with thick Styrofoam padding panels; well packed.
Remember, two subs is better than one sub, it's da law.
Hope the above helps.
