I am curious if there is an interest in these...
I have thought about it -
They would be similar to what I already have made for me but would be a thinner metal - engraved to say
Polk Audio with SDA below it
Predrilled for binding post and a SDA connection - the only downside is you would have to enlarge them to whatever you would need them to be...
I would probably be able to do them for around $24.00 a piece with a minimum 20 quantity order... (from the factory of course)
