rll Posted October 15, 2009 Share Posted October 15, 2009 Well, I'm in the beginning stages of building another pair of Cornscala cabinets. This pair will be veneered, and I'll lower the woofer so that I can replace the ph800 with a Fastrac at some point. I'll provide a blow-by-blow pictorial later on. Panels have been cut, but before I cut the port holes and get the biscuit joiner out, I want to double check a couple dimensions. The set of Cornwall plans running around (I don't have them with me at the moment, so I'm going from memory) calls for the port shelf to be 3 1/8" above the bottom, and the port holes to be 2 3/16" x 6 7/8". By my calculations, total area for the three port holes comes to 45.12 square inches. I've seen advice that 50 square inches is the desired/recommended/preferred/correct area for the port holes, so I'm putting out out a request for confirmation of those numbers. I don't have a pair of Corns handy, so I'd be grateful if someone could measure the actual dimensions of the port holes and the height of the port shelf from the bottom of the cabinet and report back. Or perhaps someone can say it's close enough. To me, 10% shy seems at least somewhat significant, thus the request. Thanks, Randy Quote Link to comment Share on other sites More sharing options...
