We now have a procedure for removal, shipping and reinstall available for you guys below.1-Removal. Just be sure and mention to me when ordering or add to your paypal payments, etc. of heat shrink and appropriate amount of cardas silver/copper solder available for you guys upon request for $6 per kit. We have had a great number of you request a kit for re-installation so we now have the 4 pcs. Regardless, in these VERY rare instances I still must be clear that we cannot cover this issue. The second tweet's voice coil former literally separated from its diaphragm due to either a bad adhesive job originally, slight overheating, or just a really bad hardening of the ferro fluid in its gap. It was part of a pair and the mate was as easy as pie. As of August of 2012 I found my first non-repairable tweeter sent to us. All T-33's have this issue as all are over 10 years old at this point. This is strictly for those with T33's that just no longer have good midrange or overall volume and need new ferrofluid. I MUST be very, very clear that I do not repair blown or damaged diaphragms. I am still stunned at the difference it has made in my meridians.

Feel free to send them to me and they will return in amazing condition. It is a tedious process but I have decided there must be hundreds of thousands of customers in need of this service given soooo many kef 33's in the field. The difference in sound was mind-boggling! The tweeters degrade so GRADUALLY over time you don't really notice until things are simply awful. After obtaining the hard to find (and expensive) ferrofluid and diving in, I was able to very successfully remove the actual tweeter, its diaphragm, thoroughly clean the voice coil former, the magnet's gap, replace the ferrofluid, re-align, and successfully re-install the faceplate. I have been an accomplished audio tech since around 1986 so I decided to research the potential repair of these tweeters. I began looking for replacements but realized quickly that most any NOS T33 was still the same age as mine and would certainly have ferrofluid in near as bad of condition. apparently the ferrofluid in the original kef T-33's notoriously dries out leaving all of these amazing tweets quite handicapped by today's standards. After purchasing a pair of Meridian M30's and being disappointed in the sound I remembered as being more/less amazing in 1988, I began to research why. That specific version did not use the fluid. PLEASE NOTE.if you own the T-33A (or sp1074 tweeter), you DO NOT need this service. The T33 was used in simply dozens of Kef speakers. ****Please read!!!!! See our recent testimonials below. Important new shipping changes below as well. Pictures are for reference only!!!!!!! If you offer and expect tweeters, you will pay for the relist fees. IMPORTANT!!!!!! PLEASE understand that this ad is for the ferro fluid cleaning/replacement SERVICE of a single KEF t-33 tweeter and not for the actual tweeter itself.
