Crazy Idea? OR not?

Discussion in 'Amps and Cabs [BG]' started by Bassline_Delux, Jan 6, 2005.


  1. I've read through the 'Cabinet Building 101', but this is more of a should I, rather than how can I. I was thinking of building a 6x10 cab with an impedance of 2Ohms. I'm not too sure this is doable, or desiarble, but that would let me use my Peavey Firebass to its full potential, and I really like its sound. The Firebass puts out 700W@2Ohms, so the cab Would have to take that, which shouldn't be a problem. And if on some later date I decided to change to a pre/power configuration, most high-end poweramps can take a 2Ohm load, right? Basically, I'm asking if its feasable, or just a waste of time..

    Its certainly feasible. If there are 4 ohm 6x10s (and there are, even if some are 5.3333ohms) then you can half the resistance of every dirver to get 2ohms surely.

    About the extent of my knowledge. :)

    you can do it, but i wouldn't.
    there aren't a ton of heads that can power two ohm loads, and if one day you decide you like one of the many great heads that can only power down to 4 ohms, you have yourself an unusable cabinet. Likewise, there are power amps that can power 2 ohms, per side, but those same amps can only power 4 ohms in bridge mono mode.
     
  4. Ya thats what I thought, thanks. Just a thought.
     
  5. It could be because I'm way too lazy but I'd just buy a 4*10 and a 2*10 both 4 Ohms... or If building is your thing build them! I know it won't sound exactly the same but there's no reason it won't sound as good!

    That way you always have the option of using a head that only does 4 Ohms! Add any power amp and power both cabs! OR if you go pre/power you can just use each channel to power each cab!

    Also you don't always have to lug a 6*10 around... although that might not be a problem for you!

    To expand on matt_dutyfree's idea, how about a 4 Ohm 4x10 and an 8 Ohm 2x10. Net impedance is 2.667 but that way you send 2/3 of the power to the 4x10 and 1/3 to the 2x10 so every speaker gets the same power . . .
     
  7. I thik I may be able to get a 2x15 Mesa Boogie for $225(Wow), 800W (4Ohms). I'll sell my current 1x15, and put that under my 2x10. That should kick some ass.

    P.S. Apparently this cab has 2 400W speakers and I can power each individually at 8Ohms each or mono at 4Ohms, pretty cool.
     
  8. or use 16ohm speakers and build a pair of 5,3330hm 3x10" cabs!

    I havn't actually worked this out but: how about building it with a 4 ohm and a 2 ohm input? It can be both.
     
  10. I'd thought about that. But the only way I see that could be done is by adding resistors and ****, and I'm not too sure how that'll affect the sound.

    its not so much the sound as it is a waste of amp power. in the 4 ohm setting a bunch of the power your amp produces will be wasted.

    How about 4, 16 ohm speaker in parallel hooked to a switch jack (marked 4 ohms, output number 1) then 2 more 16 ohm in parallel that connect at the 4 ohm switch jack connected to another output jack marked 2.6 ohms.

    Now you have a 4x10, 4 ohm cab inside a 6x10 2.6 ohm cab.

    ?
     
  13. It'd be more practical to have the cab switcheable between 2 ohms and 8 ohms. A simple DPDT can do this if you have two 4 ohm drivers or four 8 ohm drivers or eight 16 ohm drivers. But with 6 drivers, that won't work out to exactly 2 ohms with either 4, 8, or 16 ohm drivers (not and have them all draw equal power). And I sure wouldn't go below 2 ohms....
