TFL 760 Filter (eating tweeters)

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I suspect the filter in one of our TFL 760 is broken. The cabinet destroyed multiple tweeters, while other cabinets were doing fine with the same amp/ cable/ ...

I heard this is a common problem with the TFL 760, is there any more information about this? What exactly is breaking the tweeter?

How would I go about removing the filter? If I understand correctly, the tweeters will be 8 ohm if the filter is removed, not 16 ohm?

I recently found a post by Quentin Mrtk comparing the original CD-103 to a EV DH3 with the following measurements:
Green: original turbosound 
Blue:  Dh3 electrovoice

This seems like a huge difference in response. I always thought the CD-103 is a rebadged DH3, but is this not true? Is it best to get the destroyed tweeters recoiled, instead of replacing them with DH3 diaphragms?

	This thread may have some relevent info... Turbosound Floodlight internal protection filter - Speakerplans.com Forums - Page 1 A passive crossover or filter won't change a drivers impedance, but if it is damaged the driver can easily be blown. I suggest you take it out and inspect for damage, and then repair as necessary.
