help with speakers [message #16738] Wed, 22 February 2012 09:56   Worlddrum13 Messages: 7 Registered: September 2011 Junior Member hey all. i have a 1970 k100 and matching jensen 212 cab. i am wondering if anyone has any pictures of their jensen speakers so i can identify mine as being the same. there are no markings or brands on mine anywhere that i can find. they have the big square magnet and the chrome dust cap. i dont have any pictures of mine at the moment but im hoping someone on here does. i just want to verify that mine is original or if they are "after the thought" speakers. any help would be great. thanks!

If you want to see what a original to your cabinet vintage Jensen C12N looks like,with its black and gold lable, check out Jensen speakers listing on the ebay site. The new Jensen company makes a C12N model again and they sound 96% of a match to my orignal ones from 1968. The CTS guitar driver is a little lighter in the mids than a Jensen to my ears!

The best way to tell what speakers you have it take the back off. Then you know for sure. After 40+ years, no telling what might be in the cabinet. Also if the speakers are original, there should be a Kustom Logo paint stamp on the frames. Regardless of brand, each speaker should be 16 ohm each for a 8 ohm total load. pleat Report message to a moderator

I was able to take a look at my speakers. Nothing mentioned above seems to match up with what I have. My speakers are square magnet, silver dust cap. No brand stamped anywhere on it. "121638g" and "67 742" stamped on them. Report message to a moderator

I have a set of 4 from 1983 in a Risson 4 x 12 cab from Bob Rissi and beside it weighing a ton, it is the best sounding 4 x 12 cab I have ever owned....even over Vintage 1960 Marshall cabs. They are cheap to buy too. (the speakers). Report message to a moderator

Re: help with speakers [message #16751 is a reply to message #16738] Mon, 27 February 2012 12:51   Worlddrum13 Messages: 7 Registered: September 2011 Junior Member Did kustom use these speakers or did someone put them in later? They did sound good. I actually swapped them for newer speakers that handle the lows better. I'm using mine as a keyboard amp. It sounds great with the Rhodes. I thought the extended range would be a little much for the "stock" speakers. Report message to a moderator

The next step up was the Jensen drivers, and up from that was the Altec Lansing 12" driver. Report message to a moderator
