Shakey, I own a 4-way system, which began life as Green Mountain Audio Imagos, not sure about the version, but that's irrelevant because only the original cabinets remain.
How do tweak these to world class performance?
Re-wire using Dueland's four nines silver ribbon inside wire or version 1.0 or so.
Move the crossovers to the bottom of the speaker (instead of in separate boxes) eliminating
connecters that rob both signal strength and quality.
Upgrade the cross-over components, and finally roll in NOS drivers, except for the current construction super tweeters. Flavor cross-over points to taste. If you use the "good stuff", allow 150-200 hours of break-in time, with a signal playing through it, before any serious or critical listening.
