FDP Forum / Fender Amps: Vintage (before 1985) / Was this speaker ever used in a Fender amp.

I don't recall ever seeing this particular model Jensen used as a standard speaker from the factory? Does anyone have any idea what these were used in?

I don't recall finding one of these in any Fender I've seen or repaired.

That LMI number looks like it could be a Hammond organ part number. They had Jensen put a Hammond number on all speakers starting in the late '50s sometime.

Hi roadhog!

I´m pretty sure these speakers were made in the later 60´s (when Fender didn´t use Jensen-speakers anymore) and were often used as replacements when the original speakers went toast - I don´t think they ever came as factory-equipment.

carsten is correct. The Vibranto series had higher temperature voice coils and were used, mostly, as warranty replacements. Ampeg used a similar speaker, the EM Series, in their SB12 marked "Concert Series". They were basically the same speaker; a C12P with a 40 or 50 watt voice coil and fiberglass former. The EM stood for Electronic Music.

So Fender stopped using the Fender labeled C12NA speakers in 1968. I don't remember ever seeing one with 68 date code. So these Jensen Vibranto Speakers were used in place of the C12NA and C10N from 68 on. The reason I'm asking is I've recently come across two 68 Bandmaster cabinets both have these speakers and the owners said they were original. I've never seen these in any old Fenders before but there's always something new to learn about these. Just because they were destined for a Hammond organ doesn't mean that Fender couldn't have ordered them from Jensen for replacements. A lot of other manufactures used the JBL D120F speakers in their cabs and JBL designed these for Fender. Thanks everyone.

Fender didn't use Jensen's in 1968. By mid 1967 they were using Oxfords and later in the year Utah's. The brown and gold labeled Jensens were only used for a very short time, roughly from late 1965 through early to mid 1967. The LMI is not a Hammond code, it's a Jensen code. I believe it stands for Lifetime (warranty) Musical Instrument. These were some of the last speakers Jensen made and may have put them out of business. They folded in 1972. Fender may have stocked these for warranty purposes and, in theory, could have used them in closed back cabinets, where it wouldn't matter if the Fender label was visible.

That's kind of what I was trying to say, I've seen quit a few 1965-1967 Fender labeled Jensen's, I actually have some from 66-67 but I have never seen any from 1968 now I know why. If your right and I think you are, it would explain why I've seen the Vibranto's in a few Bandmaster cabs from 68. It certainly makes sense. This stuff should be documented.

I bought a Jensen Vibrato in around 1968 as an upgrade for my blackface Deluxe Reverb. It came with a lifetime warranty as mentioned above and was unblowable even with my deluxe dimed and using a distortion pedal. A great speaker!

My used Tremolux cabinet came with 2 ceramic vibranto's in it, but one was trashed (the magnet was coming off the speaker, if I remember correctly). So I have one vibranto LMI (220818) and one Jensen C10N (220024) in it now. My Tremolux cabinet is probably from 64 or 65, as I don't think they made them in 66 (certainly not in 68) so the speakers must have been replacements, maybe for blown?

Every Vibranto I've seen was in a small PA or movie projector extension speaker cabinet. I have a couple I use with low-wattage amps like a ZVex Nano, Hotone head or as a Greta extension cab.

Related equipment with them has dated them to late 60's not 60's...but that's just the ones I've come across.

That pic looks very much like the Jensen "Lifetime" 15's I got in 1967. Just a different, but similar sticker on the basket. Still got mine, but think one is blown. Hmm..
Now, where did I put that lifetime warranty certificate?
