We’ve finally completed the latest revisions to our new PCB “Daughter boards”. These attach to the back of the speaker driver and provide attenuation (a pad) to the speaker increasing the impedance which in turn results in more voltage from the amplifier at the terminals.
This is coupled with new surface mount LEDs with proper current limiting which gives really good brightness both backwards and now forwards through the transparent cone!
All in all this is an exciting improvement and early tests are very promising.
