All of our G3 full-range speaker use the same mid-high section with horn-loaded midrange driver and coaxial placed high-driver. This ensure even sound quality, sound characteristics and phase response not only when using the same speaker model but also when mix speakers within the G3 series if necessary. Sound engineers will save time for setting up whole application by using standardized equalizer setups for the series and no need of adapting miss-matched phase responses by all-pass filters.
