Default Symptom Diagnosis please?

After a short play with my fynction generator in one of my two 15" Tannoy monitor I found that while in 100Hz raising the volume beyond a sertain point the sound comes a bit distorted, like a higher frequency is introduced together with the 100Hz(compared to the other. Any hints of what that may be? Maybe a loose turn on the voice coil? Any loudspeaker expert in here lease help! I am really desperate!

Sincerely,

Panos

My mistake! Forgot to mention that the test was done free air (on my bad) without the use of any kind of crossover. The differense is very obvious during the test between the two drivers.

I did, both measure 6.5 Ohms and there absolutely no scratch when pushing in or pulling out the cones.

Actually I noticed during loud passages of electric guitar and specifically at the beginning of brothers in arms frrom dire straits that the small solo was a bit distorted so I switched to mono and listen the same just changing speakers. The feeling is like tha amplifier distorts somewhat more than usuall. But its now definitely the speaker that looses control at 100Hz as tested afterwards.

Dear Joe,
I really thank you for taking the time to answer to my question, I am afraid this is the case and although this is a very easy driver to take apart its extremely costly and hard to find spare parts. Damn, use to love that driver.

Thanks again
