If you've ever had trouble installed boxy speakers in corners, JBL has heard your cries. With the JBL Control NOW Speakers, you can easily mount speakers in corners without leaving that awkward space behind them.
With a 90 degree shape, the speakers are much easier to mount and are modular, meaning they can be connected together to wrap around a corner. Up to four speakers can bracket together in this fashion.
JBL is known for producing top quality audio products, so there shouldn't be much of a problem there. These speakers are also known for producing evenly distributed sound and minimal distortion. But these speakers aren't cheap. Costing $225 a piece, you'll need to save up for a full set.
