Although the humble subwoofer
is probably the least likely to require placement inside a space that's beyond cable reach -- or concealment -- thanks to its non-directional sound frequencies, JBL and Infinity have teamed up to solve the problem anyway. The PS212W is a 12-inch $679 400W sub with an included 2.4GHz wireless transmitter / receiver bundled: yes, that's 2.4GHz, the same frequency nearly all your other wireless kit uses. JBL's Cinema Sound CSS10W also uses this overused frequency for its wireless, but it's only 10-inch and 300W, and will retail at the lower price of $559 when it launches in January next year.
