Dual outputs with amps with speakon and normal 1/4" ouput...?

Discussion in 'Amps and Cabs [BG]' started by Kevin_BlueBASS, Apr 26, 2009.

  1. Hey,
    My Yorkville XS400C combo has a speakon 1/4 "and normal 1/4"
    and I was wondering if I could plug two smaller extention cabinets into it-
    one per output jack (8 ohms each proabably since the amp is 4 ohms)
    but before I pursue this I need to ask some annoying Noob questions! :bag:
    (sorry if there's been countless threads about this before- wasn't sure what to type in the seach bar :oops: ...

    If I were to get two 8 ohm cabs (the head in the combo runs down to 4 ohms)
    that handled say 150, 200 watts each would I be able to attain the full 400 watts from the head's rating?
    Or would each cab have to be able to handle 400 watts?
    Thanks in advance guys!
  2. I'd use the combo's 'cab' along with an 8 ohm at 200 W cab.
  3. Hey,
    Thanks for the help!
    So if I plugged a GenzBenz 8 ohm 150 watt cab, would I be powering both the cab in the combo and the ext. cab?
    Would it be any louder?
  4. It sure looks that way Kevin. 150 watts might be a bit light but if you aren 't planning on having the pedal to the metal . . .

    I found the manual on the Traynor website & only did a brief read of it. It's worth getting & you might as well get the Service Manual while you are there; worth having even with a Yorkville.

    Be careful plugging in too many speakers, watch your ohms, don't go under. The result will be a dead amp. I'd think one ext cab would be more than enough, plus, the amp isn't designed to push that many speakers anyway. Stick to what it says in the manual.
  6. So it WOULD work to have both the (250 watt 8 ohm) speaker and 150watt 8 ohm cab run at the same time? (The amp is rated 400 watts at 4 ohms).
    I'll be able to access the amp's full potential and it will be louder right?
    (Sorry for the repeditive questions lol)

    Yes, a whole 6dB. You get 3dB from the extra speaker, and 3dB from the doubled power. It isn't much in most cases.
  9. Hmmm.... so ANY ext. cab would only boost it 6db?
    I think I'll go for it anyways...
    the 1x12 coupled with the 1x15 can only bring more punch and definition!
