E-140 on a SVT-15 cab ?

Discussion in 'Amps and Cabs [BG]' started by iguana, May 29, 2012.

  1. Well....I'm selling my Ampeg B-100R. I tryied putting a E-140 on it (rewired in 4 ohms) for a while. It was better that the original speaker at high volume, but in general wasn't what I was looking for.

    Whats the idea? Sell the combo, buy a head, and built a cab to put the E-140 on it. The question is, which cab? I cant buy a cab here (the prices are prohibitive) so I will built one. It could look like a Fender or Ampeg I really dont care, but my question is about dimensions.

    I don't wan't a giant cab, with something a bit bigger than the combo is ok for me, so I was looking with interest the Ampeg SVT-15 cab. What you think?

    Thanks in advance.

    Sorry that makes no sense to me. Would you reword it to make your meaning plainer. I know that English is not your first language. :)
  3. I bought the speaker damaged, without the cone or coil. So when I sent it to recone I asked to do it in 4 ohms instead 8.

    I have the E-140 apart from the combo. The combo have his original speaker installed right now
  4. Finally I built a SVT-15 cab with Fender's look (to match the rest of the band). Inside it's a reconed 4 ohms JBL E-140

    Im really happy with the sound. It's really a step forward compared with the Ampeg B-100r

    Now I can play in large stages and I can heard what I play with clarity.

  5. Nice work!
  6. you should ask why a reconed speaker, why the Fender's look, why why why why....and the answer is "cost"

    I live in Buenos Aires, Argentina, and Ampeg prices are totally crazy.

    An original Ampeg SVT-15 used cab here, is about 1500 american dollars, and a PF-350 its near 900

    I did it all for half the price.

    I think you have done very well, it looks great, bet it sounds really good too.:bassist:
  8. Thanks man :) I'm happy with the result, it was what I was looking for.
  9. Well, I had the E-140 on that cabinet for a year, but the sound was too hard. I decided to try a Peavey Black Widow (an old one I found) and I have to say that this speaker match the cabinet better than the JBL.

    I'm not saying that one speaker is better than the other, I just think the E-140 needs a bigger cabinet. The Peavey with his longer cone movement, produces a homogeneous amount of low bass in all the strings, something impossible with the E-140.

    So, Black Widow on the cab, JBL gone, and some money back on the pocket.

    Glad you found a driver that pleases you. Regarding the disappointing performance of the E140, it's worth remembering that the cone, surround and voice coil are critical elements of a driver. All else being equal, a 4 ohm voice coil used in the E140 magnetic structure would likely have substantially reduced Qes and Qts. The stock E140 driver is arguably, overdamped to start with. The 'new' 4 ohm driver would likely be heavily overdamped, resulting in mid and low bass being several db below the mids - a very unbalanced sound quality.
