I know crazy, i havent contacted klipsch yet, i feel like a numbnut for not knowing, but yes frickin fantastic jump in transparency, im waiting for SET12 on this forum and on the audiokarma forum who has those ridiculous xovers on his fortes to chime in and let us know if he's ordered them or has them already, he showed interest last i spoke to him, I guess the only thing that beats this would be beryllium diaphragms if thats even possible, would probably cost some serious beaucoup bucks tho, but klispch or crites for insanity's sake lets make it happen, wouldn't mind some 30hz-50khz Forte's !!
