Has anyone heard of these speaker?


I picked up a pair of TETRASOUND speakers in a pawn shop and they are incredible...I have heard they were developed by an Canadian. Does anyone have other information on these?

I love pawn shop finds. How much did you pay for them? There's a review of the Tetra 506 in this month's Tone audio webzine:

Kkm and Elarado... neither of these websites are the speakers I have... mine have a about a 12 inch metal logo with the word TETRASOUND...
