Project21 - Part II - subwoofer and DSP system

In L|A Vol 0 Jean-Claude described the development of the P21 mid-high satellites with optional passive cross-over. The satellites are now complemented with an active subwoofer. A DSP cross-over and correction unit integrates the subwoofer and satellites into a very high quality audio reproduction system. Jean-Claude describes the driver- and DSP selection process and gives guidelines how to get the most out of the DSP system. The article also describes a completely built unit and is finalized with extensive tests and measurements. Level- and balance control of all amplifiers in the active enclosures is achieved with an RF remote control system, described in another article in Vol 1 by Jan Didden.
