According to Greg dunn's dynaco site,These speakers
were released in the late 70's and information on them is scant.As I understand there were models-
40,60 & 80. Anyone know which model they are ?

I sadly have No intentions of pursuing them and have No
affiliations with the listing~

Dunno about the model, but I'm pretty sure that's a Seas tweeter and mid in there...nice bits.

Here's a quote from Dunn's site (Thanks Greg)

In the late 1970s, Dynaco released a short-lived set of new loudspeakers developed under Ed Laurent's supervision before he departed to join SEAS Corporation. The "Phase III" speakers were highly respected, but their introduction was apparently too late to make any strong impression on the audio industry.
