System Design Suggestions

The Velodyne product you have purchased was designed to offer you the greatest amount of flexibility possible in your vehicle's sound system. However, due to the nature of the servo-control circuitry, there are some suggestions you should observe to avoid any problems and ensure maximum performance. Please read and observe these requirements before proceeding with system instal- lation.

●When choosing an amplifier, it must have extended low frequency response down to at least 10 hz

●Optimum performance is typically realized with one dedi- cated amplifier per woofer

●Amplifier used must have gain adjustment

●Amplifier used should be capable of supplying woofer with a minimum of 100 watts RMS

●Maximum suggested amplifier power is 300 watts RMS

●When installed in a sealed enclosure, the unit may require an amplifier towards the high end of the scale (200-300w); when used in an infinite baffle setup, power requirements are reduced and satisfactory performance may be attained with a smaller amp (100-200w)

●Sealed enclosures: accurate sound, simple to build but require more amp power than other enclosures

●Infinite baffle: accurate sound, simple installation, lowest power requirements

●Ported enclosures: much higher output, low power require- ments but more complex to build

As you can see from this diagram, the speaker and amplifier now become part of a loop. Actual cone motion is monitored, so now we can control the drive signal to the amplifier. In essence, controlling how the speaker responds.
