[QUOTE="Strainger, post: 1071557, member: 839"] Tweeters on Tannoy Mercury M3s failed. Markc blessed me with a pair of BOXED Tannoy Sixes mk 2 tweeters(603, 605, 607) - for free... thank you so much! The tweeters are still on their way from Mark, but I am wondering about the following: I do not have the exact specs of the tweeters, but as they are in the specific speaker models, there is a difference in crossover frequency and sensitivity: (Old) Tannoy Mercury M3 tweeter: 25mm (1") soft dome 8 ohms Sensitivity : 89dB (2.8Volts @ 1 metre) Crossover Frequency: 2.7kHz Crossover type (description): 2nd order low pass. 3rd order high pass. (New) Sixer tweeter (as inside Tannoy 607 ii): 25mm Gold anodised aluminium dome 8 ohms Sensitivity : 88dB (2.8Volts @ 1 metre) Crossover Frequency: 3kHz Crossover type (description): 1st order low pass. 1st order high pass. Would it be possible to overcome the 300Hz difference in crossover frequency? [/QUOTE]
