70's fender blue-label speakers: worth reconing?

Post by crow » Wed Jun 25, 2008 12:04 pm

i thought i'd get some opinions on whether i should get some blown "special design" 12" speakers reconed, or just get new speakers. i have 4, but only need 2 for a 2 x 12 bassman cabinet i'm putting back together. i suppose that since i'll probably use it to record bass with (i won't be gigging with it), maybe i should get some EVs.

I've had this cabinet (and the matching silver bassman head, which is awesome) for years and never cared for it (as a guitar cab), and a borrower blew the speakers, but right before i was about to give/throw it away, i saw in Recording the Beatles that Paul used this exact rig for a lot of later beatles stuff. naturally, i figured "well, if it's good enough for P-Mac (o god, i didn't really write that, did I?), maybe i should really give this thing a shot."

i'm leaning toward ev's, but am mulling it over and would love to hear some two-centses.

if you want to use it as a bass cab, the EVs will be nicer than the blues.

ebay the blue's and buy EV's. Alot of guitarists (including me) like the sound of those 70's blue magnets.

It totally depends on the EVs though! I find the super high wattage EVs dont sound as good as the lower watt ones. Apparently someone at Mesa Boogie agrees with me. The mesa version of EVs are just the Force series with the magnets from the EVM series.
The best EVs are those old ones with the chrome frame (why is a part you dont see chromed?) and the hammertone coffee can cover over the magnet.
Man I wish I had my old cabinet back!

I think they are the SP15? Not entirely sure. google image search shows similar looking ones called sp12. It has a chrome frame and a pinkish/brownish hammertone finish "coffe can" on the magnet.
Last one I had about 12 years ago. I think it had an alnico magnet. I used to play it through a 1x15 cab with an acoustic 450, later a traynor YBA 1a MKII. Best bass tone ever. Louder than 2 tubes and one speaker have any business being. Lost it to an unscrupulous landlord.

on further research, the SP12/SP15 appear to be the whizzer cone version. Mine had a plain ribbed cone, with a copper colored script EV logo. But aside from that looked just like the SP15
Man I wish I had never thought of that speaker. I need one for my Mesa cabinet now!

nah, mine had a different label, and it was brown not white. I found a pic of it from google search on audioheritage, but their site somehow foils deeplinking their photos.

I don't know how reliable this is, I heard the round blue label 70's Fender speakers were CTS.
not to worry, just keep tracking....

The blue labels out of my 70s twin were CTS. You can look up the codes to figure out who made them.
guitar files wrote:The first 3 are the manufacturers code

137xxx = CTS

304xxx = Stackpole

140xxx = Clarostat

134xxx = Centralab

381xxx = Bourns

106xxx = Allen-Bradley Speaker Manufacturers codes

220xxx = Jensen

465xxx = Oxford


The next number(s) is (are) the year. Initially this was a single digit, latter that was extended to two digits for clarity.

The last two digits are the week of the year. Note that if these digits are larger that 52, it probably is NOT a date code!
Whales!
