Mesa Powerhouse 1000 Question

Discussion in 'Amps and Cabs [BG]' started by Sanctum, Nov 13, 2003.

  1. So I was checking out one of these cabs in a store recently and noticed there are two jacks on the back of it

    one 4 Ohm
    one 8 Ohm

    Mesa's site says its a 4 Ohm cab, so I was confused. I understand on tube HEADS why there are different jacks for impedance, but don't understand it on this cab really.

    Hey Sanctum, what's up. I got to play thru one of those as backline (borrowed) and if I remember correctly the cab is bi-ampable. I think the 4 ohm jack was mono and there were 2 8 ohm jacks for bi-amp mode. Awesome cab!
  3. Yea thanks - I was there again today and noticed the "bi-amp" small print that I missed before. That sure is one loud cab.

    It's wierd, but if you hook the 4 10s up to an amp, then switch to the 15, I think the 10s go deeper. It seems senseless to me to biamp it. I had other 4-10s/ 1-18s, Etc. that I could have biamped, but I always went back to full range.
  5. Yea, I think I'd actually prefer a 6x10 to the 1000.

    Or two of the 4x10's. Those little cabs really crank.
  6. It occured to me today that I could run both sides of my Eden WT-800 into the 1000 @ 8Ohms. Wouldnt have to biamp either, but would have that option on the fly.

    If I remember right the WT800 is 400 or 380 x 2 into 4 ohms each. Bridged is 8 ohms only. The cab is 4 ohms full, or 2- 8 ohm separate inputs. It would be better to run the Eden stereo into each input. So you would be running 2 - 4 ohm outputs into 2-8ohm loads. I think that's better than running an 8 ohm output into a 4 ohm cab.
  8. yea ... thats what I said ......

    Its 400 watts per side at 4 Ohms, or 260 watts per side at 8 Ohms, or 800 watts bridged at 8 Ohms.

    If you plug into an 8Ohm load you're not getting a 4 Ohm output.
    By "both sides" I meant both speaker outs on the amp to the two 8 Ohm inputs on the cab.

    Not Bridged.
  9. Crap I wasted my 1000th post on that!
