Hear Every Line
A silky-smooth 25 mm soft-dome tweeter keeps voices razor-sharp, while dual long-throw 4-inch woofers fill out mids and low-end effects with confidence. The result? Speech that cuts through the action without sounding thin.

Slim Footprint, Easy Fit
Measuring just 140 × 322 × 186 mm, the low-profile cabinet slides neatly under your telly or projector screen, freeing up shelf space without skimping on output.
