Hello, I found the coil to be rubbing on the pole by cutting the dust cap off as described in a past post. I thought the problem might have been dried glue bouncing around, but found long drag marks on the aluminum tube that the coil is wound to. I figured this happened when I over threw the woofers while playing a Mannhiem Steamroller CD this past Christmas. (There is a passage that jumps out with a huge Kettle Drum and was using an Adcom 5500 Amp and have since went to Audio Research tubes.) I only heard the problem while certain tones were reproduced. The KP-28-E's go for $127.01 apiece. I have the feeling that these new woofers are not of the quality as the K-25-K. Just to lift one up is a difference. And no foam backing gasket is included. This is the one between the woofer and the encloser. Tech support gave me a name and e-mail for a guy who is supposed to do nice recone jobs. I think I will give him a try and just keep these reconed K-25-K's on hand if a problem comes up. Are these KP-28-E's a real recent model? Cannot find any info on them. Thanks for the help!

Hello all, I have a question on the differences between a K-25-K woofer and a KP-28-E woofer. Three days ago I called and talked to tech support about a woofer that was emitting a scratching sound.( Found to be the coil dragging on the pole piece.) I was told there are no longer K-25-K woofers available but have a better woofer, the KP-28-E. I asked the differences and was told that while the speaker will take a while to break in, I should not notice a difference. This is fine. Was also told that the woofer has a higher power capacity and has a larger magnet structure. Sounded great...I ordered two, to keep both speakers matching. They arrived today and noticed that the magnets appear much smaller. I weighed them and found a 1.5 pound difference. They sound fine. Will be better once broke in. But am wondering if they will last. The frames are the same. There are no longer rubber surrounds, but rather look like the radiators with a rib type surround. Are these O.K.? Are the magnets better now? Should I just recone the orginals and write off the KP-29-E? Can not find another speaker that uses this type. Thanks for any input. I just want to keep these wonderful speakers the way they always were. They sounded great when I purchased them new and still love em. Thanks
