Bruce, perhaps you already know this, but you may wish to contact Ken Haerr ([email protected]) out at UplandloudSpeaker for some suggestions. Harvey Gerst once suggested I contact him, and Ken did a D140F re-cone and inspection for me. Great work.

Thanks Captain Bob.
I actually spoke to Ken a few times this past two weeks.
No doubt he knows his stuff.
Thanks for the suggestion, Bruce

great stuff john. i had a vintage d140f in a guild cab ported that sounded fantastic. i will probably get another one for a fender bassman single 15 cab i'm planning on. too bad they didn't make 4 ohm d140f.

i recommend a K140 if you can find one. it sounds almost exactly like a 'D' but handles twice the power. the K140 is still my favorite 15" of all time.
I just scored a mint set of JBL K140's. Cant wait to get them into a 2x15 cab.
I've have a Tech 21 Landmark 300, lying around as a backup amp. Should go nicely with this cab.

i know that you'll love 'em. and since they're so efficient/sensitive, it'll make you amp sound like it has twice the power of conventional 15"s.
john aren't the K's the really heavy ones? or is that the E's?
i might get a CTS too. The ones with aluminum vented dustcaps from organs are 4 ohm and are super cheap and available. I've heard they sound great, cross between a standard paper cone CTS and some JBL love. they are ribbed.

the E's are the heavy ceramic magnet ones. the D's & K's are alnico.
Can a E130 16ohm be reconed to 8ohm ? I really need it to be 8ohm. I want to use pair it with an 8ohm E120 for my 4 ohm output 1972 Fender Twin Reverb amp. My Fender only has a 4ohm tap.

Question. Is a JBL D120F magnet assembly the same as a JBL D130F magnet assembly ? Will they interchange ?Yes the impedance is in the voice coil which is part of the re-cone kit.X

so the k130 has 103 db sensitivity and the k140 (same as d140 which i have) has sensitivity of 98 db.
does this mean if i sold mine and got a k130 my amp would be able to produce louder cleaner notes further up the volume dial? old tube fender bassman

Well, I've asked Beans on Toast about the differences between the D130's and the D140's. I'm sure you know that Ampeg used the D130's as an upgrade in their B-15NL(Lansing). The voice coils in the D130 are Copper clad Aluminum, while the D140's are all copper. The D130's have a little better lower midrange emphasis. That said the D140's
were great bass speakers
