The MPBX 250 S2 ultra-flat closed subwoofer has been specially optimized for the performance of the MPS 250 S2 subwoofer. Thanks to the 15 mm wall thickness, the housing structure shows unparalleled stability. The internal sound-absorbing material increases the volume of the subwoofer and reduces acoustic vibrations. The internal bracing between the panels minimizes resonances, the rounded corners make placement easier. The 2S² (two sides/2 sounds) design allows you to choose where to place the speaker. It can be installed in the downward radiating position with the included feet, increasing the low-frequency extension, and if installed in the upper position, it produces tighter, more dynamic tones. The SSP (Sub Smart Plug) Plug & Play terminal blocks and traditional compression spring connectors enable a stable connection and quick release.

Ultra-flat, closed housing specially optimized for the performance of the MPS 250 S2 subwoofer.

15 mm (0.59 inch) wood thickness for unmatched stability.

Internal panel bracing with solid corners to minimize resonances

Rounded corners for easy placement

The internal sound-absorbing material practically increases the volume of the box and reduces acoustic resonances.

The 2S² (2 Sides/2 Sounds) design allows you to choose the position of the speaker as you like.

It has both SSP (Sub Smart Plug) Plug-&Play terminal blocks and traditional compression spring connectors

Strong screwless full metal grille with adjustable logo position

Ultra-flat structure designed for shallow chests

The Air Intercooling Revolution (AIR) prevents air pressure restrictions.

Unique mechanical swing, +20% more than traditional designs.

Six-layer copper voice coil (38 mm/1.5 inch) provides high heat capacity.

The ultra-flat, closed housing has a 15 mm wood thickness that provides unparalleled stability and durability. Rounded corners make placement easier, while internal bracing minimizes resonances, guaranteeing clear sound.

The 2S² (two sides/2 sounds) design allows the subwoofer to be placed on any side, so you can easily adapt the sound to the interior of the car. It can also be installed in a downward radiating position with the help of the included feet.

The MPS 250 S2 subwoofer has a continuous load capacity of 500 W and an impedance of 2 Ohm. Air Intercooling Revolution technology prevents air pressure restrictions, while the die-cast aluminum frame and six-layer copper voice coil ensure durability and excellent heat dissipation.

SSP (Sub Smart Plug) Plug & Play terminal blocks and traditional compression spring connectors make connection quick and reliable. The screwless full metal grille with adjustable logo position protects the speaker from damage.

Hertz's research and development department has developed the patented AIR (Air Intercooling Revolution) technology, which optimizes the air flow in the inner chamber of the voice coil and the magnetic unit. Thanks to this, internal air compression is reduced to a minimum, while maximum cooling efficiency is achieved.

Thanks to the SSP (Sub Smart Plug) technology, the MPBX has both a Plug-&-Play connection block and traditional spring (push) speaker connectors, which enable a secure, reliable connection and quick disconnection.

The 2S² (2 Sides / 2 Sounds) design allows you to choose the installation direction according to the desired sound. With an upward-radiating arrangement, a more powerful, tighter sound and better definition can be achieved, while the lower-radiating mounting - with the help of the included feet with Velcro inserts - provides a deeper, more extensive bass range.

The internal sound-absorbing material increases the volume of the subwoofer and reduces acoustic vibrations, while the bracing between the panels minimizes resonances, so you can enjoy deep, clear and dynamic bass in your car.

Internal bracing and rounded corners not only reduce resonances, but also make it easier to place the subwoofer in the car, thus providing excellent sound even with maximum use of space.
