JBL E140's - Anybody like them?

Discussion in 'Amps and Cabs [BG]' started by LoveThatBass, Mar 13, 2005.

  1. I just bought one but haven't received it yet and wondered what your opinions are on this speaker? I plan to use it in my Avatar B115H bass cab.

    I use E145s - I think the E140 is more of a low frequency air mover. They will last forever if you don't abuse them...

    That's back to front. The E145 goes much lower and is a better suited as a bass giutar speaker. I wouldn't ever part with my E145.

    I know some of the old Sunn and Fender speakers used E140's, but that was in their 2x15 cabs.

  4. So, how would you characterize the E140?
    Lows, mids, highs and overall sound?

    It's a good speaker. I'd characterise it as a specialist mid-bass driver. It doesn't go too low, which is why they used to use 2 of them. It apparently has a punchy but smooth response right through the range. It pretty much gives up at 2.5K so it will need a tweet of some sort to get some highs out of it.

    What are the dimensions of the cab you're planning to put it in?

    I was looking at getting some new speakers for my old fender cab. Here are the inside dimensions of my cab.
    H = 28 1/2 inches
    W = 26 1/2 inches
    D = 9 1/2 inches
    What do you guys think? :confused:

    That's about 117 litres. Is it a 2x15 cab? And is 9.5in deep correct? That seems very shallow.

  8. Weird. They state it goes from 40-2500 hz. You would think that would be low enough.

    Well technically every speaker ever made goes to 40Hz. The question is how much it is doing down there. If it's 10 or 20dB down at 40Hz, you won't hear it. That's why "Frequency response" specs are useless for anything other than marketing tools.

    In a 27litre cab, which is the recommended size for QB3 alignment, the E140 is -3dB at 96Hz. As far as I know the Avatar cab is bigger than 30 litres, so it may go deeper in that cab if tuned properly. I run in E145 in a larger-than-recomended cab and i've measured it to be -3dB at 50Hz. For reference, a typical 4x10, despite manufacturer claims, is -3dB at roughly 60Hz.

    I can run a simulations through WinISD pro if you like, but I'll need the Avatar's dimensions.

    I agree, the 140 is not a good low-bass driver. I used 'em plenty times back in the 70's. And had one up to a few years ago. really a smooth good sounding speaker, but it dosen't handle the lows. E-145 would be the ticket if ya gotta go JBL. I always preferred my EV's if I had to use a stock off the shelf speaker in a bass cabinet, that is until I re-discovered Eminence. Love my Kappa Pro LF. Its kinda what Jim Bergantino uses. Anyway, sorry for the ramble.

    Good lows but the mids and highs are not good. Have to rely on a Horn. I was hoping to get by without using a horn. I like lows but also, the spacious sound of good mids and smooth highs.
  12. If you do not mind that would be of great help to me.Thank you in advance for any help you might lend here.

    27"H X 25"W X 16.5"D (outside)
    Vented at the bottom 21/2" x 25"

    inside would be 24 3/4" H x 23 1/2" W x 14" (speaker board recessed 1 inch)
    Not counting the vent area

    The E140 was used in the JBL Cabaret bass cabs which I used years back. Went plenty low enough, it was just a beast to haul around. I'm sure the E140 will do fine in the right cab.
  14. Thanks Reefer...how did it sound in the mids and highs (bass wise)

    Well, it's been 20 years since I used one, but it was definitely more of an old school sound. The Cabaret sounded great with the E140, but I tried the E140 in other cabs and didn't have as good as sound as the Cabaret. But the Cabaret was a much bigger cab than the others I tried.

    One of the best sounds I ever had was the Cabaret with a SWR SM400. Very rich, full bodied tone. I have very recently gone back to 15's after using 10's and 12's the last few years. I just can't get that '70's sound out of my head! :)

  17. The old Fender and Kustom cabinets from the late '60s and early '70s actually used D140Fs. Not absolutely certain about Sunn though...

    Ohh. That got my attension. Tell me more! :bassist:
  19. The E140 is loud, very efficient, but has a very short Xmax. Proper tuning is very high up the scale, so it is not particular well suited as a bass guitar driver, but more for vocal PA use above 100 Hz.

    The E145 is a whole lot more suited for electric bass. If you can find an E145 with authentic factory cone, grab it. These are highly engineered drivers, and one of the very few with an under hung voice coil. Very linear, very punchy. Huge magnet.
