I've got a spare 044ti for my 240ti's lying around. Curiousity got the best of me and I was able to get it apart without damage. As expected, the foam pad is mush. I would imagine the two in the speakers are in a similar condition, and that may explain why I found them rather dull sounding when I bought them last year. I have since reduced the resistor value from 5.1 to 3 ohms on the tweeter circuit, and they sound much better to my old ears.
On to my question: I have two pieces of 1/2" thick foam at my disposal. I have determined that the more open, filter media foam is easier to compress but it feels more "springy" and has an almost plastic quality. The other foam is also quite soft, albeit more firm and "damped" feeling than the media filter type. Does anyone have a suggestion as to which would be the better option to use as a replacement ? Looking at a pic of a diaghragm kit here as best I can, it almost seems as if the original foam was somewhere in between my two options......
Also, should I apply a signal to the tweeter when re-assembling to center the voice coil ? If so, at what frequency ?
Many thanks for any advice !
