Stupid question - but!!

I have read up on building slot resonators and understand the basic principle. I have downloaded the calculator however, What I don't understand is what frequency I should aim for ie. what size slats and spacing, when putting the slats up on my inside out wall? Here's the room with the slat walls showen. Thanks JohnG

Really not that deep. Do a quick cal to see what is the narrowest spacing you'd do (most people it's 1/4" or 1/8") and the widest slot spacing. For me that was 3/4" That will tell you the bottom and top frequencie of absorption by the resonator. Nothing to fret about. :) The main reason I recommended it was to keep the room from being to dead. :)
