After shipping damage did in the first SPK5 speaker @sgoldwin sent to Amir to test, another was sent with the crossover mounted internally. The second had an unknown issue, but was sent to me to fix. I later identified the issue as an incorrect polarity marking on the crossover board. Not sure where it happened, but the brace had broken free too and I had no simple way to fix. Rather than have me fix, @sgoldwin decided to send me another. This was around the holidays and it never made it to me ...
After some more iterations that need not detail here, we figured out 2 things. First, despite appearances, the Purifi crossover was NOT meant to be mounted on the brace. Second, the back baffle was leaking and needed to be sealed. So this set of posts documents the design mods done to redress.
Let’s start with the before pic...
Note the crossover mounted on the brace and the nice foam tape used to seal the back baffle. This pic also lets you see the twisty port design of the SPK5. Not as obvious is the wear spot where it is rubbing against the woofer coil (notice the light area on the edge at about eight o’clock).
