Woofers – max frame diameter – 187mm Tweeter – square frame 120mm max I was considering having an aluminum plate or wood baffle cut to fit the front of the egg enclosure to facilitate mounting drivers and not having to deal with matching the existing mounting points/frame shapes. (see photos)
The Egg is .46 cubic foot volume with a 2″ rear vent pipe that can be trimmed to tuning frequency. The rear also has a terminal cup with gold binding posts. They are painted gloss black and look amazing when polished…
Since the terminal cup is removable, bi-amp designs are within the realm of possibility.
The Focal Eggs were reviewed in the 3/86 issue of Speaker Builder. The author commented, “the vented Egg is the best-sounding small full range speaker system I have heard.” I hope that with new drivers and electrics it will be possible to bring them back to this high level of performance.
