Delaying all frequencies is easy. smile

The "problem" is *progressive* group delay in the lower bass frequencies, especially in ported speakers (there's no escaping the physics). In the bass drivers, EBA corrects this by applying variable delay to less affected frequencies, to bring every frequency produced by the same driver(s) to the same group delay value. Non-bass drivers *do* have a constant group delay applied to bring them in line with the corrected bass drivers.
