Looks like the woofers are marked L.T.L Electronics out of Auburn, WA. Being that the name badge on the speaker grills is Audio Phase, I'm guessing this is way of cashing in on Phase Linear name which was also built in Western Washington.?.
Audio Phase Speakers + Calrad
I picked up a pair of "Audio Phase" (speaker grill badge) speakers today at a sale. Definitely late 1970's look. The cabinets are really nice and heavy with resessed speaker grills. It has 2 horns, tweeter and a 15" woofer. Has 2 controls, one marked "Calrad" the other has an animal on it. I see no other markings. Are these some high school wood shop project or a legit system? I've heard of Calrad, but not Audio Phase.
