You do not have real music-listening enjoyment until you have the right bass sound and that gut-busting feeling in the pit of your stomach. And that is something the new blue subwoofers can do with incredible ease. Rich deep bass sound and high, undistorted maximum sound pressures are the guarantee. And as if that were not enough: thanks to their new dual voice coils with 2 x 2 Ohms of impedance, all the woofers now allow much greater freedom in system configuration.

- Massive and rigid aluminum die-cast basket
- Massive gold-plated terminals
- Solid rubber magnet protection ring with HELIX logo
