Problems with Infinity Prelude MTS mid-range

I contacted the Swedish company that services Infinity (and JBL etc.) and amazingly they just had another MTS speaker in that had the same problem with thew 3.5" driver, sold at the same HIFI dealer as mine. The service man showed me the reason it sounded bad (same reason as stated earlier in this thread), and that it was clearly a manufacturing problem, probably due to magnetic material being present when they made the driver.
So he replaced both the 3.5" (left and right speaker) at no cost! "When you buy Infinity you should get good service, and these were faulty drivers from the beginning ..."
He had never come across this before and now he got two customers the same week!

Anyway, now that new drivers may be ordered you might as well have the speakers serviced if you have started to hear som buzz - it will get worse, believe me!

Magnus,

Thanks for the information. Hope the replacement 3.5's have the problem resolved. I will contact my dealer and see if he will do the same for me. As I live in the U.S. where the customer services the company instead of the other way around, I will probably have to replace the speakers myself. I have the complete surround system and two MTS w/ sub for a dedicated room. Every 3.5" driver has a problem now except one. Listening to a pair of Audioengine 2's instead of surround right now, and bought a pair of Dunlavy's for the dedicated room. Perhaps the New Year will find working Preludes again as they are excellent sounding speakers.

I have this problem with my midbass. Has anyone managed to repair them in a repairshop? (not infinity) Since i hear the problem is with some peeling, i thought maybe it could be cleaned, and thus repaired.

Has anyone tried/done this??

Well, I have Infinity Prelude Compositions since I think 2002, and I hope these problems don't crop up. I really like them a lot. They're especially good with low powered SET, better still if you can give them just a little more juice. The Cary V12 and Cary 300B are wonderful with the built in sub (25hz). The Primaluna Dialogue One I own also performs well, my brother's Leben CS660 is really a nice match. I always wondered why more people with moderate low-powered amps were not purchasing speakers such as the Prelude Compositions? These speakers cost about $3,400.00 back in 2002. Good luck solving issues, HK sucks for not owning up.

I change MTS for a pair of Tyler Acoustics D1 last year, GREAT DECISION. Didn't missed them.
They had more problems every day, first the mids, then one sub, then...
If you need spare mids or anything, let me know, I can sell them. The only problem is that I live in Ecuador and shipping will be expensive. I have 3 subs, 2 tower and a center speaker.
