48P48 EAS Subwoofer & Controller Although this project is covered elsewhere, it is worth adding it here for convenience. This has proven to be a very popular project since it was first introduced, and that interest has not waned. Using the ELF™ "Extended Low Frequency" principle, this processor is designed to operate a sub-woofer driver below its resonant frequency. This means that the box is small, resonance can be (comparatively) high, and the load is completely predictable.

71Linkwitz Transform Circuit The Linkwitz Transform circuit is an equaliser to provide extended bass response from any loudspeaker in a sealed enclosure. The effect is similar to the EAS equaliser described in Project 48, but the range is no longer only below resonance, but encompasses the normal frequency range of the driver. Updated 06Aug
PCBs available
