Hello I am new here and to Altec horns. I was given a pair of Altec 1202b. I am wondering if they can be modified for home use. the sound pretty darn good as is with the stock 807-8z horns and the 422-8z woofers. I am really surprised given they are old pa cabinets. I have some tannoy monitor gold so I know good horns. I stuffed them with 4 lbs of fill each and the tubbyness is gone. Does anyone have any experience modifying these? These are VERY close to being amazing speakers. I greatly appreciate any response.Thanks,EC
