  • Your experience with modifying raw loudspeaker drivers and the results.

    I would like to know what some people have done to improve a stock loudspeaker driver and if it was an improvement over stock units. This based on actual testing results of before and after and you actually hearing a difference. ?

          The "Scam Speak".

          Many otherwise normal people put rope caulk or other damping material on stamped steel speaker baskets and are quite happy.

          There's that "Enabl" thing, sticking little triangles on the cone, not sure if I spelled that right. That's mostly over at diyaudio, IIRC.

            Had a stamped steel framed speaker that pinged like a bell, did something 'bout it - made me happier.

              This hobby is all about happiness. Normal is over rated. And I didn't say "dampening".

                      I've done the slits to a dead paper driver just to see if I could. Turned out okay, but I was of course not able to listen to it. Josh Bruner's slit-PM180 sounded quite good.
                      I've had to reglue phase plugs into drivers, with no ill effects.
                      I've adhered thick and heavy sport flooring tile (ground up tires) to driver chambers externally to eliminate ringing. This was very favorable. Adding mass in this instance has always been a benefit so far.
                      I've reglued terminals to drivers that had them breakoff.
                      I've added felt peel and stick dots to drivers that needed them.

                      Later,

                          I have read them several times and they very interesting. I dome similar mods to tweeters with good results.
