That bad driver in a multi-mid/woofer setup may not be bad afterall....................
The past week I have been suffering with what I considered to be a bad driver on my SDA1Cs. It smacked, clacked and generally made a hell of a racket when a drum kick or deep bass note sounded at high volume. I couldn't recall any time that I had really driven them too hard or to the point of mistreatment, but it was definately not working in unison with the other mids in the box. Late last night I took the driver out to see for sure what model I needed to look for, I noticed one of the speaker leads had come loose. Hooking it back up, problem solved.
SDA mid drivers in a sealed box/passive radiator design without a signal runnng through them to control excursion become the passive radiator. Being only 6.5 inches, they easily move too far and reach the limit of their travel in a most noisy and uncomfortable sounding smack.
Just thought I would pass on what may be obvious to some here on the forum, but we have had a number of members listening to speakers that are for sale find SDAs that had a mid driver that made racket at high volumes and assumed that replacement was neeed. I found out the easy way, this isn't always the case.
