1 Rob Williams 1 year ago Howdy, The only experience I've had with Dynas' are the Korean built Electromatic DeArmond 2000. Didn't like them. Too much quack and no love. Love my HiLo's in the Tenny but there seems to be alot of Dyna love. How would you characterise a REAL Dyna vs a HiLo? Can you mount a Dyna over a Filter cavity?
