Cornnuts Posted November 26, 2001 Share Posted November 26, 2001 I just purchased a set of KG 5.5 from my brother. The speakers have been in storage for 2years. One of the horns has no sount coming from it at all. I did the obvious and switched the working horn with bad to eliminate the drivers, but the good horn worked fine in both cabinates. I took the horn apart and noticed some oily stuff in the speaker maganet where the cone slides into, is this normal? The working horn had the same condition but doesn't seem to impeed its performance so my guess it's there by design. Can I get the horn tested? Should I just replace it? Any recomendations for a retrofit horn if it can't be replaced? Quote Link to comment Share on other sites More sharing options...
STL Posted November 26, 2001 Share Posted November 26, 2001 You probably just need a new diaphram which should run less than $40 I believe. Just call Klipsch (at 1-800-klipsch). I believe the oily stuff is ferrofluid and is used to help keep the voice coil cool by helping transfer the heat from the voice coil to the magnet structure.

WMcD Posted November 26, 2001 Share Posted November 26, 2001 That's interesting. I've never seen any advertising about ferro fluid being used by Klipsch. And noone replacing diaphragms on the Heritage line has mentioned finding any. However, your post teaches us something new. Gil Quote Link to comment Share on other sites More sharing options...
JohnA Posted November 26, 2001 Share Posted November 26, 2001 PhilH mentioned several months ago that ferrofluid is so common now nobody bothers to mention it. I believe he said Klipsch has used it in selected drivers for some time. John Quote Link to comment Share on other sites More sharing options...
STL Posted November 26, 2001 Share Posted November 26, 2001 I agree that ferrofluid isn't anything special (as far as calling out its use). I have opened up tweeters in a KG4.2 and KV3 and neither had any ferrofluid. I wonder know if it could have "dried up" or if those drivers never had it.
