Does anybody make 2ohm cabs?

Discussion in 'Amps and Cabs [BG]' started by Alex, Apr 19, 2006.


  1. I am on the verge of buying an amp that can do 2ohms, but I don't want to/can't afford 2 different 4ohm cabs, yet I would like to take advantage of the extra output. Does anybody know of any 2ohm cabs that would be good as a standalone?

    Thanks

    Maybe, but it would be rare. It's relatively minor surgery to turn an 8-ohm cab with two 4-ohm speakers into a 2-ohm cab (i.e., wiring them in parallel rather than in series).
     
  3. Power doesn't mean anything by itself. You have to factor in the sensitivity and frequency response of the speaker. More power won't necessarily sound louder if it's going into a less efficient cab.

    If volume capability is your concern, you would get essentially the same volume benefit (or more) with a more efficient 4 ohm cab that you would by going to a less efficient 2 ohm cab, and you wouldn't be running the amp at it's limits. It's a good idea to avoid running an amp at its limits if you can.

    Are you sure that this amp just doesn't go down to 2 ohms, which would mean that it really uses two 4 ohm cab. IMHO I would suggest that you check the info on this amp, and make sure it uses a 2ohm cab and not two 4 ohm cabs. My amp is old like 30 years and it goes down to 2 ohms, I'm from that era and I don't remember a amp that used 2 ohm cabinets, I'm not saying there wasn't any I just don't know of any.:bassist:

    I wouldn't recommend buying a 2 ohm cab even if you can find it. Later on down the road you will want another cab for a different kind of sound and you will wish you had a 4 ohm so you could just add another on.
     
  6. You seem to be implying that most 2ohm cabs aren't efficient. Is that the case?
     
  7. The impedance of the cab has nothing to do with how sensitive it is

    What amp? I am asking because most amps with 2-Ohm ratings are fairly powerful, and a single cab that can absorb your amp's output power is probably not going to meet your affordability requirement.
     
  9. No, I'm not implying that at all. I'm just saying, you seem to be assuming you need to get the max power out of the amp. Presumably because you want max volume or headroom. My point is that just having the max power available does not mean you get max volume or headroom. 300 W into a very efficient cab gives you more volume and headroom than 600 W into a very inefficient one. So I'm saying that to look for a 2 ohm cab just because you get the most power out of the amp that way is looking at the problem the wrong way, because it doesn't guarantee you what you want. It makes more sense to look at other considerations first, such as tone, frequency response, sensitivity, and price, and then see how things look as a system with the amp you're envisioning.

    I've never actually ever seen a 2 ohm cab.

    Get an 8 ohm multi-driver cab, and then rewire it for 2 ohms...

    I believe ampeg made some cabinets that were biamp-able o could be run at 2 ohms. Check them out, versital if you ask me.

    i think there was a 2x8" and 15" 2way, and an 18" 2x10" cab. They are kinda rare, but they are out there.

    Many (most?) 8 ohm 4x10" cabinets can be rewired to 2 ohms, if they contain four 8 ohm drivers. Rather than series/parallel, the speakers could be rewired to parallel.

    I think the reason why we haven't seen many 2 ohm cabinets is because until fairly recently few bass amps were able to drive 2 ohms loads. Seems that 8 ohm cabinets used to be the standard, where two cabinets could be combined with heads that were rated to drive 4 ohms, while many are now moving to using two 4 ohm cabinets with 2 ohm rated amplifiers.

    There's a 2x8/1x15 cab at my local guitar center, and it's pretty lackluster. Sounds good, but isn't efficient at all.
