    Awesome! Thanks! I purchased a set of already modded T50RPs, so I've been in reading/researching mode to try and figure out any changes I'd like to make. But my pair sounds amazing already, not sure if there's much I'd change save for a touch more extension in the low end.
  2. ardilla
    Cleaned up formating. Added "Materials" - please contribute... EIther as a comment here or directly in the editor.
  3. cn11
    Maybe it would be useful to make up a list of materials mentioned in the thread (I know that my head gets to spinning every time I spend any length reading in the thread, and I can't keep track of what material is what!). It could be edited on the go, with useful info like best online retailers to purchase from, as well as current going prices.

    ^What he said.
    A+ will read again.
    P.S. Is there a guide to leakypants somewhere? open-air T50RP.
  6. JamesMcProgger
    Very nice thanks. I'll be refering to this wiki when I get my T50pr someday
