Thanks for posting. Another listening of the DR-1's (approximately forty years later) needs to be on my bucket list.

Cheers,

Dave.

At Bell Labs, I tested a phenolic-fabric fried-egg tweeter a local dealer had cornered the market in. Fabulous looking tone bursts and good freq response. So a group of us bought a case of 'em and I made a 120 degree array using 9 per side (which obviously simplifies the cross-over).

My experience is this: big tweeter power capacity is more worthwhile than I ever used to think; there definitely are moments in music where giant peaks occur in the high treble instantaneously (for example, female choirs). And apropos this thread, seriously multi-directional tweeting adds a welcome liveness to the sound of music at home as compared to the usual beaming treble (and esp. for us ESL folks).
