technical question about adding a second cab

Discussion in 'Amps and Cabs [BG]' started by rolliefingers, Apr 6, 2006.


  1. i apologize if this has already been covered, but i need technical support and couldn't think of a better resource... i usually use a gk rb1001-II w/ an eden xlt 4x10 cab . tonight i'm playing with a stupidly loud heavy rock band and have been asked to use a 2nd cab - i have a trace elliot 1x15 i was thinking of adding. so i've got an amp rated at 700 watts @ 4 ohms, the eden rated at 700 watts @ 8 ohms and the trace rated at 300 watts @ 8 ohms. Question: will this work or will it put any of my equipment at risk? sorry if this a dumb question - i'm not too knowledgeable about wattage, impedance, ect... thanks.

    This will work just fine. Two 8ohm cabs equals a 4ohm load.
     
  3. thanks for the quick response xgabriel - i figured the impedence would match up, but i didn't know if the power ratings for the amp w/ these cabs would present a problem or not.

    Nope, the cabs should handle it just fine. Have fun!

    I don't know what the sensitivity specs are for the eden, but if I recall correctly, my Trace 1x15 was pretty inefficient, so the eden might be a bit louder???

    I would tend to agree with this here. But if the Trace 1x15 is all he has, then it should help round out the low end ok.

    This is good info. I have a Ampeg B2R that I use with one Aguilar GS112 which is 8 ohms - I believe the Ampeg is rated at 240 watts at 8ohms, and it seems underpowered. I will likey buy a 2nd GS112 which should give me a 4ohm load and my Ampeg would then push 350 watts. I've never really understood ohms... I just turn it to 11 and play...

    That B2R seems underpowered because it is underpowered. Nice tone, but you need a real efficient cab with that head to get any usable volume out of it.
