Wildly fluttering woofer


Without any kind of warning the left woofer of my Thiel 7.2 speaker started fluttering-the excursion was at least two inches. Won't happen with a CD. Tried another record and the same thing happened again. I have not switched speaker cables.
System: VPI Mark IV turntable with Graham Phantom arm and Dynavector XX2 cartridge, McCormack DNA 500 amp, Audible Illusions Modulus 3B pre-amp, Thiel 7.2 speakers, all wires are Audience. HELP!

I haven't checked my posting in a while hence the delayed response to your last post. Without sounding like a sycophant, your communication skills blow me away.
My left leg which has a Jones fracture of the fifth Metatarsal bone got another cast yesterday for another month. Don't know if I mentioned that I retired on April 17, bought a Honda Civic Si with six speed manual transmission two weeks later, and fractured the bone two weeks after that. So, the car sits!
According to Art Ferris at AI, my pre-amp checks out O.K. and will be returning soon. Meanwhile I can listen to music thru a Yamaha C-60 pre-amp with interestingly MM &MC(with variable loading).
Changing caps on my Thiel 7.2s is way beyond me and tube rolling sounds interesting but I'd still be hesitant to experiment. Maybe I'll run the idea past Art, although I can predict the answer. I will however engage the sub sonic filter om my 3B.
Since the pre-amp seems O.K., I have to consider that excessive tracking force may have caused the woofer flutter. Hope to hear from you again...
Thanks for taking the time to care, Katz1
That kind of fracture can take a while to heal, as you are coming to realize. Sucks about the car, I can relate. I broke my neck 7 days after purchasing a new Subaru Outback and wasn't allowed to drive it for 4 months. A couple of times I sat in it just to take in that "new car smell".

Check the capacitance setting that you're using for your cartridge, too much and it can boom. Wherever you moved your turntable may coincidentally happen to be the worst spot in the room for a turntable. Corners, for example can be boomy.

You'll figure it out. Now's the time to relax and be thankful for what you have and make the best of your situation. I felt like listening to Michael Jackson one night and recorded the playlist. I called that CD "The Halo Session". Good CD, very reflective of my mood that night.
Dear Heyraz, you might have fit another piece of the puzzle-the turntable is in a corner, I have always listened with the TT cover up/open. I too sit in the car and start the engine-it's better than nothing.
What happened to your neck and did you need surgery?
By the way, have you ever heard of the "Ukulele Orchestra of Great Britain"? Check them out on you tube.

I am going to check out Ukulele Orchestra. The name alone has my interest. Have you ever heard Vaughn Williams "Concerto for Tuba"? I couldn't resist that title.
When I landed on my head the force broke C1 into three pieces. It's called a Jefferson Crush Fracture and it's similar to what would happen to a pretzel ring if you slapped it on a table. C1 can only absorb so much force, after that it splits. A bad bop on the head is all it takes.
The C1 fracture wasn't as life threatening as the subdural hematoma, in fact the C1 issue wasn't realized for two days. I told the doctor that my neck hurt but not in the usual way (I had C5-C6-C7 fused the year before because of herniated discs). In fact, during the car ride to the ER I supported my head in my hands because it felt like it might fall off of my neck. I walked into the ER supporting my head, covered in blood looking like Carrie at the prom, and passed out shortly after.
After I awoke from the brain surgery, the doctor asked me if I had a runny nose, to which I replied "funny you should ask". He shot a picture of C1 through the roof of my open mouth which showed the C1 fracture as well as a fracture to the spenoid bone, which is behind the ocular orbits, one of which was also fractured. My "runny nose" was my cerebral spinal fluid leaking out.
Fortunately for me, I needed no further surgery, just rest and a halo to keep my head on straight so C1 could mend. Because of the trauma, the retina in my left eye also detached, but laying in bed for a few days gave it the opportunity to lay back down and re-attach by itself. That issue was realized many months later during an eye exam. I complained of blurry vision while I was in the hospital, but by the time they got an ophthalmologist to examine me, the retina had already settled back, my vision cleared up, and nothing was seen till scar tissue formed later on. The runny nose stopped by itself, and thank god my body did a great job of healing itself. I just needed food, rest and time. I was forced to take the summer off, so I adapted and made the best of the situation. No complaints, I could have easily died, or worse.
As a bonus for my pain, I got a great torque screwdriver out of the deal. It's very precise and calibrated so the halo can't be over tightened to the skull. The halo is in my shed hanging from a hook.
So take it easy and try to enjoy the down time. If you're like me, you'll come out of the gate fast once you're medically cleared. You just have to be patient.

Reading your medical story was a harrowing ride. Since I'm an atheist, and don't believe in miracles, your'e one lucky audiophile. My "pinkey" story is, hands down" almost like a burp in comparison. I hope you buy lottery tickets because it seems you buck the odds.
Whenever I need a little pick-up I give the U.O.o GB a listen on you tube. A friend in London turned me on to them two years ago and I saw them live in Santa Barbara, California a few months ago. Afterwards my wife told me I had a grin on my face for the entire concert. They were almost as good as Versed and Demerol.
My wife started a "social enterprise" called Kishe' foods about a year ago. Her goal is to support small scale coffee farmers in Guatemala and also diversify their sources of income. It's a giant undertaking as my wife(2nd) has no prior business experience. We have 37,500.00 lbs. of green coffee arriving on the west coast in two weeks and we're still trying to develop a marketing plan. Please visit kishefoods.com and check out the web site she's building. Let me know what you think. We could use your writing skills.
