HERTZ MPS 300 S4 Mille Pro Series 1 Inch Shallow-Mount 4-Ohm Component

Subwoofer

Congratulations on purchasing our product. Your satisfaction is the first requirement that our products must meet: the same satisfaction as the one gained by those who long for experiencing the car audio emotion. This manual has been drawn to provide the main instructions required to install and use the system properly. However, the range of possible applications is wide; for further information, please feel free to contact your trusted dealer or our technical support at the email support@elettromedia . it Before installing the components, please carefully read all of the instructions contained in this manual. Failure to respect these instructions may cause unintentional harm or damage to the product.

1. All components must be firmly secured to the vehicle structure. Do the same when installing any custom structures you may have built. Confirm your installation is solid and safe. A component coming loose while driving may cause serious damage to the passengers, as well as to other vehicles.
2. Always wear protective eyewear when using tools, as splints or product residue may become airborne.
3. In order to avoid incidental damage, keep the product in the original packaging until you are ready for the final installation.
4. Do not carry out any installation inside the engine compartment.
5. Before starting with the installation turn the head unit and all other audio system devices off, avoiding any possible damage.
6. Make sure that the location you choose to install the components does not interfere with the normal operation of any mechanical or electrical devices of the vehicle.
7. Do not install loudspeakers where they may be exposed to water, excessive humidity, dust or dirt.
8. Do not install the components or make cable run close to electronic or mechanical devices of the vehicle.
9. Be very cautious when drilling or cutting into the vehicle chassis, making sure there are no cables or structural elements essential to the vehicle underneath or in the selected area.
10. When routing cables, make sure that the cable does not come in contact with sharp edges or near moving mechanical devices. Make sure that it is firmly attached and protected along its entire length and its insulation is self-extinguishing.
11. Only use cables with the proper section (AWG) indicated herein.
12. When running the cable through a hole in the vehicles chassis, protect the cable with a rubber ring (grommet). Be sure to provide proper protection for cables running close to heat-generating devices.
13. Do not run the wires outside of the vehicle.
14. Use top quality cables, connectors and accessories such as found in the Connection catalogue.
15. Warranty certificate: For more information visit the Hertz website.

ENCLOSURE DESIGN MP/MPS
In the following pages the Hertz Tech Team developed Sealed and designs for MP and MPS subwoofers. They are ready-to-build solutions, including the panel cut list, considering wood thickness 19mm (0.75in.) for MP and 16mm (0.63in.) for MPS series.
The Vb data is the net volume for the enclosure, i.e. it excludes the speaker volume, ports, any internal bracing and any other internal component.
The declared Fb is the actual tuning frequency of the box realized according to the ready-to-build solution. This geometry can not be accurately modeled using lumped parameter-based design software, hence those software may produce different results.Regular and Shallow variants for MPS series provide the same performance in just a different shape. Regular has the widest application while Shallow is the “solution” where low-depth is a matter.
Sealed enclosure designs provide optimally damped response for tight and accurate bass reproduction offering high energy in the range 20Hz-40Hz.
Where a high SPL bass is desired, and space is not a problem, the Reflex designs are the best choice concentrating most of energy in the 40Hz-80Hz range.

*The Thiele and Small parameters are measured with coils in parallel. For series coils specification multiply Re and Le by 4 and BL by 2, all other specifications remain the same.

The Thiele and Small parameters are measured after the speaker has been conditioned by a specific signal and represent the expected long term parameters after a short period of use.
