How can 8″ loudspeakers properly reproduce low frequencies?
Long ago, Ampeg sold a superb bass guitar rig called the PR-810H Dual Bass Cabinet. If you ever heard a PR-810H, you know cone area is more important than individual cone size in determining how efficiently LF is reproduced. Specifically, LF radiation efficiency is defined by membrane surface area and excursion. The 8 loudspeakers used in GEO systems display very high excursion. And, because most of GEO-T LF energy is forward-radiated, the LF radiated by GEO T provides a higher output than a comparable 2x 15 LF section could provide.
