Good info on Leslie vintage speakers. One correction: The Jensen C6435 number is NOT a date code. It is the "Cone Code", which specifies the cone, voice coil, dustcap, and spider combination for this "Special Design" version of the P15LL. The source/date code number combination for Jensen will appear as a 220 number followed by 3 or 4 additional digits which indicate the year and week of manufacture. Here is how a typical EIA Jensen source/date code 220341 would break down: 220=Manufacturer=Jensen. 3=last digit of year=1963 (NOTE: decades repeat. A single year digit could be '40's, '50's, or '60's). In 1970, the format was changed to a two-digit year code. Source codes were not assigned before 1945. Continuing, 41 would indicate 41st week. Some additional source codes: UTAH=328, ROLA=285, MAGNAVOX=232. Hope this adds some clarification to a somewhat murky subject.
Thank you so much for this detailed information. I have never understood those numbers and was misinformed by someone that the numbers there were a date code. I really appreciate your clearing that up for me.
I can do even better than that for you. Take a look at this speaker that I just won on eBay: www.ebay.com/itm/252785842871 Find one of these on ebay for less than $100.00. If it is already reconned then great. If not - send it to Slice Speakers of Kansas City at www.sliceinc.com/ and have John to recone it for you. You want it at 16 ohms. These cost $200 plus shipping to recone. I just looked at one of my bills today. LOLOL You will also need to place a subwoofer gasket - something like this - www.ebay.com/itm/VELODYNE-SUBWOOFER-15-RADIATOR-GASKET-SCREWS-VGC-L-K-/292047587721 under the speaker when you mount it in your cabinet to keep the spindle from tearing your new cone. This is a 200 Watt Bass speaker so it gives you more room for power and they do sound great. But with a 40 watt Leslie amp - you never use it to its max capacity. The typical Leslie bass speaker is a 40 watt speaker which keeps everything in balance. So therefore, you will want to have your amp rebuilt (recapped with new resistors), your crossover recapped and the speaker diaphragm coil cleaned on your Jensen V21 upper driver if that is what you are using. ( I can do those things for you in my shop if you wish). You can send me a message at: vintageb3organ@outlook.com if I may be of service to you. Have fun and get that Leslie sounding the way you want it sound. Thanks for the note and the request. I hope to hear from you soon. Hammond Doc!!!

Personal experience. I have tried the new one and it did not sound as good as my reconned vintage Jensen. I don't know why they chose a 40W amp vs a 50W amp vs an amp of some other wattage. My understanding is that there was variation in the wattage among certain vintage amps. For example, I understand that the 21H has less wattage than the 22H/122. The 251 amp is more powerful.
There are a variety of reasons including the condition of the amplifier, the tubes that are being used, the condition of the crossover, the condition of the organ, the condition of the Leslie cable, etc.
I have compared the new C15 to the Vintage reconned C15 and the difference is like night and day. The new ones can not compare to the quality of the vintage speakers. They just do not mount up.

btw...what is the exact difference between the 122 and 147 cabinet??
The amplifier.
explain.....is it more wattage??
There is some good discussion of the differences at this link: www.harmonycentral.com/forum/forum/Keyboards/acapella-18/332598-
But they are both 40 Watt amplifiers. I prefer the 147 personally. More gusto!!!
The 147 has more bounce to the ounce!!! LOL
why do u think the new jensen speaker didnt sound like u wanted??.. and why do u think leslie came up with a 40W amp?

Why do some Leslie's have way more bass than others

The new c15 needs to be broken in. They sound just the same as the old c15s if not better.
