I finished making a pair of untraditional speaker cabinets with Altec Bass and Altec compressor for the tweeters and dividing network crossovers , as a result they sounded good with certain genres of music , especially jazz and believe or not with techno , well more like ambient , while some music sounds incredible good other music doesnt in fact it sounds terrible, i consulted my technician that repairs my gear , i described that the higher notes sounded very pitchy , he sugested i change the ohms from 8 to 4 , that helped a lot , but still rock sounds awful , lucky for me i enjoy jazz more than anything else , but still i would like to enjoy some of the old music i grew up with, Led Zep- Stones, Greatful dead- Santana and many others , i know for a fact that not all music sound good with every speaker , that is why right now i own several pairs of them, from Acoustat , JBL . Dali da capo , , Triangle , Pioneer , old Sansui, Snells , i still would like to get my new ones to sound good with most genres after all i have spend lots of time building them , any thoughts out there what could i do to improve them ?
