More info on this woofer?


Recommended Posts

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.

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.

Interesting info. You've been with us for almost 13 years and only 19 posts! I'm honored to get one here!

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.

Greg

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.
