TEKTON IMPACT MONITORS

If one uses Tekton Design’s sensitivity specification of 94db 2.83V@1m, and enters into this calculator 150w (peak power output of the Tsakiridis Apollon Ultra amplifier), at 1 meter, speaker away from walls, the calculated decibel level is 115.8dB.

If one does the same calculation using John Atkinson’s sensitivity estimate of 87.5dB 2.83V@1m in his Stereophile measurements section of the Impact loudspeaker, the calculated decibel level is 109.3dB.

Both results are below the loudspeakers’s 120dB power handling limit (per Tekton Design’s specs).

Hopefully, Van L will provide some expert analysis to explain why the tweeters failed.

spacecadet65,
I agree with you completely. No matter how many times knowledgeable members warn of the folly of substituting drivers in speakers, there is always someone who tries it anyway.

A possible solution - don't buy a speaker where you feel like you need to swap out drivers, crossovers, and place it on springs in order for it to sound really good.

Jetter the sacd Iam talking is Suite espagnola. Asturias is a killer driver , the impact of this music will not make the tweeter happy.

Grant I will ask Van L what was really the cause, for this tweeters to burn the voice coil.
