Wiring Wizard & Port Calculator

Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!

Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.

Frequently asked questions about 12" (30 cm) bass-reflex enclosures

What is the net volume of the bass-reflex enclosure?

The net volume is exactly 50 litres and has been specifically designed for 30cm subwoofers. This size enables optimum low-frequency reproduction down to 25 Hz, whilst maintaining compact external dimensions for installation in a vehicle.

What is the wall thickness of the MDF?

The cabinet walls are made of 18mm-thick MDF, which ensures exceptional stability. This material thickness prevents vibrations and resonance, even at high volumes and power outputs of up to 500 watts RMS.

What subwoofer power rating is the enclosure designed for?

The bass-reflex enclosure is designed for speakers up to 500 watts RMS. When paired with suitably rated amplifiers and high-quality 12-inch drivers, it delivers competition-level performance with powerful, precise bass.

How is the bass reflex tube sized?

The diameter and length of the bass reflex port are precisely tuned at the factory to match the 50-litre volume. The tuning frequency is around 35 Hz, which enables deep bass without any rumbling.

Is the enclosure suitable for car audio and home use?

Yes, the technical specifications allow for both uses. In the car, you’ll benefit from its compact dimensions; at home, from its audiophile tuning for high-quality music playback.

What surface treatment is recommended for MDF?

Untreated MDF should be primed and varnished or covered with carpet. This protects it from moisture and improves its appearance – which is particularly important when it is installed in plain view in living areas.

Can I combine several cases?

Yes, to achieve even higher sound pressure levels, several identical bass-reflex enclosures can be operated in parallel. Ensure you have sufficient amplifier power and use identical speaker drivers to achieve a consistent sound.
