Frequently Asked Questions – 46 cm Subwoofers

Why choose a 46 cm subwoofer rather than a smaller size?

The 46 cm format allows for higher sound pressure and deeper bass than standard sizes. It is ideal for advanced installations where impact is as important as quality.

What enclosure or installation type for a 46 cm subwoofer?

46 cm subwoofers often require custom or large-volume bass-reflex enclosures. It is essential to carefully consider the available space and enclosure structure for optimal performance.

What amplifier power should I choose for a 46 cm subwoofer?

It is recommended to choose an amplifier with approximately 40% more RMS power than the subwoofer, so that the amplifier can operate comfortably without clipping, ensuring clean and long-lasting sound.

What role does the subwoofer's impedance (ohms) play?

Impedance indicates the load the amplifier will have to work with. A 2-ohm subwoofer requires an amplifier stable at 2 ohms. Improper matching can reduce available power or damage equipment.

Do you offer support for selection or installation?

Yes. Our consultation service via chat is available to guide you in choosing the 46 cm subwoofer and suitable amplifier. You can also request a personalized quote for complete installation.
