Angry did I damage my FF165WKs?

I've noticed a crackle in both my FF165WK MTLTs. I've swapped sources and amps still there's a "ti" sound that accentuates some female vocals and percussion like snare drums. The "tick" sound is barely detectable on most tunes but it makes others unlistenable.

At first I thought I was listening to a FLAC of a scratchy album.

I can push the cones and nothing hits so the problem isn't mechanical.

A EL34 SET powers the speakers. (8-10 w/ch)

As you can imagine this is highly troubling, I'm losing sleep.

Is there anything I can check??

Thanks, Mack

Try to get it to do the thing reliably. Maybe with the frequency sweep and then hold the offending frequency, then you will have a better chance at determining exactly where the fault is by listening with your ear to the cone.
It might just be your cabinet or some loose material in it.
Also try with a difference amp or source.

Thanks, have tried one laptop running Daphile w/LiTe AH dac and another laptop running Win7 & FooBar2000 w/HiFime Sabre U2 dac. Also Trends 10 amp.

A frequency sweep is an excellent idea. I'll try that tomorrow night.

Are your tinsel leads at the bottom of the driver?

Are the screws too tight? And you should see if the noise exists with drivers removed from cabinet.

"Too tight"? I never thought of that. I'll check tonight, thanks!

I removed the drivers, they sure sound different out of the boxes, but pop is still there.

Click the image to open in full size.

Ran a Sweep and heard no ticks or pops. I paused the player for a while, no music, no pops.

I even tidied my wiring best I could. Still the electrical sounding "ti" is there.

I powered my XMOS spdif converter from USB then a wall wart, same noise.

The distortion seems to happen when certain sounds are produced by the music.

Arrg, Mack

To completely isolate the problem, have you tried them (either naked or in enclosures) in an entirely different system - i.e. a buddy's home theatre rig?

Are you sure it isnīt just in the music itself, can you hook up some reference speakers to your amp to compare?

Do you have to play it loud to hear the 'ti' sound? Is that a teee (short) sound or a tye (long) sound? Do 's' sounds sound OK, and does it happen more with piano strikes more than other notes?
