Pete H Posted September 13, 2020 Share Posted September 13, 2020 Getting ready to sell some drivers and can't identify these particular Klipsch 15" cast woofers and the labels came off a long time ago. I've done some searches, but can't seem to find anything that clearly shows what it is. Any assistance would be appreciated. Quote Link to comment Share on other sites More sharing options...
jjptkd Posted September 13, 2020 Share Posted September 13, 2020 They look like k-48-k Chorus woofers which would be 4 ohm but they could also be early model k-45-k which would be the 8ohm version. 1 Quote Link to comment Share on other sites More sharing options...

Pete H Posted September 14, 2020 Author Share Posted September 14, 2020 Here's a picture of a set of K48K's next to them. The K48K's are on the right. Quote Link to comment Share on other sites More sharing options...
billybob Posted September 14, 2020 Share Posted September 14, 2020 My K-48-E looked like the one on the left. From memory... 2 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted September 14, 2020 Share Posted September 14, 2020 Maybe check them with an Ohm meter to help narrow the search. 1 Quote Link to comment Share on other sites More sharing options...

The ones on the right are k-48-kp pro versions of the k-48-k with ribbed and coated baskets, vented voice-coils and screw down binding posts all designed for extreme / rough use. I've seen the k-48-kp both in 4ohm and 8 ohm versions. 1 Quote Link to comment Share on other sites More sharing options...

I'm going to check them both and probably run it through DATS to get some numbers on them. 1 1 Quote Link to comment Share on other sites More sharing options...

What you may not know is that besides the KP-600's and all my TSCM's, I also used to have A bunch of MCM-1900 stuff. I had five MWM doubles and four MWM singles along with a ton of other MCM-1900 pieces. I also had a pair of KP-480's among others. I also used to have like 43 separate spare 15 inch Klipsch drivers. Your 15 inch drivers in question do look to me like the K-48 drivers from my KP-480's Bass Bins to me. Those speakers were pristine and 100% untouched. One thing I have learned from the KP-600's is that the early KP-600's had a split pair off K-60 drivers that were replaced in newer KP-600's with a single K-432 driver for greater power handling. Also, the earlier KP-600's had flat magnet K-46 drivers like your drivers in question, where as newer KP-600's have the improved "Bump Back" K-46 which allows for more former excursion and better power handling. Not saying what I am going to say next is so but, I suspect your drivers in Question may be earlier versions of the K-48 ??? Rog 1 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted September 14, 2020 Share Posted September 14, 2020 Aren't the K-43 woofers cast frames as well? Looks like the ones in my MWMs. Quote Link to comment Share on other sites More sharing options...

Pete H Posted September 14, 2020 Author Share Posted September 14, 2020 checked them and the K48K's and they all meter out to 4ohm. 4.2-4.4 on the meter. so, now I know that. Quote Link to comment Share on other sites More sharing options...

Roger The KP-43Es that are in my MWM bins are vented, but don't have the extra ribs on the spokes. I had to pull a front off to see. I couldn't remember. 1 Quote Link to comment Share on other sites More sharing options...

Marvel Posted September 16, 2020 Share Posted September 16, 2020 I would have to call Klipsch to find out the power handling of the two. My MWM cabinets, while not new, appear to be newer than a lot of the MWM bins people have posted pictures of on here. The KP43Es in my cabinets look very similar to the Eminence Legend CB158 (an 8 ohm CB15). At least the frame and back plate with the venting.
