tim -- what exactly was your mod on the 480 ??
Ey up ira, First off i changed the tweeters and crosovers and replaced them with a spair set of m90 tweets and crosovers
Then i put a set of my replacment woofers off one of my m90's now here comes the inportant bit, i drilled about 20 holes in the back of each speaker box alowing the speakers to breath i know thats the kind of thing you would do ira
But my god what a differance it sounds as clear as an m90 easily and the boxiness has gone and been replaced by a real deep warm bass.
I had totally forgotten about my mod when i pulled the box out eirlier expecting the same not so good sound (well i diddn't like it) but instead it was Realy like listning to my x m90 i would recommend anybody to have a go what a diferance in sound.
