Speaker ID? Homebrew, maybe?

[Trolly90]

Greetings everyone! I picked these up a the local Habitat for Humanity Thrift and thought they looked interesting...

They stand 20" tall, 10" wide, and 9" deep, but haven't tested them yet, maybe next week.

Anyone with any ideas/thoughts on the manufacturer of these or are they homemade?

As always, looking forward to your responses!

Looks like a P.A. speaker. Cabinet construction appears more complicated and better finished than most home brewed speakers (mine of course are an exception ).

Dynamic Speaker Corporation was a legit manufacturer, once upon a time. Their logo/monogram was a bit different tho.



Better sound through research... was a Bose tagline at one point in history.

I also have searched over the years to try to find information on the "Dynamic" speaker brand. There is also another one with the same logo but it is called "Major" brand speakers.i can find very little on either brand.
