greg928gts Posted May 19, 2012 Share Posted May 19, 2012 This is from a 1964 Klipschorn. I'd like a little more information about this woofer. If anyone can help out it would be appreciated. I will be selling it on ebay. On the PWK tag it says K33J Greg Quote Link to comment Share on other sites More sharing options...
Guest " " Posted May 19, 2012 Share Posted May 19, 2012 It's a klipsch k-33-j, made by Jensen used in early 60's klipschorns. it was used with the larger throat opening (6X12 instead of 3X12) and used with the edge deflectors. Quote Link to comment Share on other sites More sharing options...
greg928gts Posted May 19, 2012 Author Share Posted May 19, 2012 Thanks SF. I was thinking Stephens, but wasn't sure. The Khorn it came from has a 3 x 12 opening and a larger splitter than normal. No edge deflectors. 1964 decorator model. Anything special about the value of these? Greg Quote Link to comment Share on other sites More sharing options...
filmofreddy Posted May 20, 2012 Share Posted May 20, 2012 Hi Greg, The K33"J" is a renamed Jensen P15LL. Jensen introduced the P15LL in the very early 50's. It was used in the Jensen Imperial Folded Horn. The only Difference in the Version they made for Klipsch was a 4 ohm Voice coil vs. the standard 16 ohm. The 16 ohm version was also used for years as the bass driver for the leslie organ cabinet. A very good woofer but, it's achilles Heel is it's lack of power handling. I like those throat deflectors in SpeakerFriz's picture. Lots of experimentation in the early 60's when a dealer discovered (through measurement) the nosedive the K-Horn took above 250 cycles. Klipsch scrambled for a cure when He hit upon the idea of a constricted throat (from an original of 78 square inches down to 39 square inches) that gave the K-Horn an artificial boost in response to compensate. That was another impetus for the developement of the K400 Horn. Quote Link to comment Share on other sites More sharing options...

So the grumbling distortion that is an iconic part of the B3 sound heard on recordings is partly from a P15LL just about to rip apart? Wonderful! Thanks.

WMcD Posted May 22, 2012 Share Posted May 22, 2012 I found this on the Jensen and presume it applies to the K-33-J. WMcD p15ll or K33J TS Parameters.pdf p15ll or K33J TS Parameters.pdf p15ll or K33J TS Parameters.pdf Quote Link to comment Share on other sites More sharing options...
Guest " " Posted May 22, 2012 Share Posted May 22, 2012 the k-33-j will run out to 3K which is much farther than most bass woofer....not being a smart ***...but it would make an awesome lead guitar amp driver. Quote Link to comment Share on other sites More sharing options...
