RE: Subwoofer with ESL 63

Thanks for the clarification and additional info Josh. I forgot to mention that Danny Richie recommends the side panels of a W-frame made from the plans he provides on his site be doubled---an extra 3/4" layer of MDF be added to each side---to stiffen those side panels and prevent audible resonance. Either that or put in a brace connecting the two panels together, running across the open cavity of the "W". Of course, there is nothing preventing one from doing both!---Eric.
