another rig question

Discussion in 'Amps and Cabs [BG]' started by cobrasneverdie, Jun 13, 2003.


  1. i am gonna get a new rig in a month or two but i am just wondering if 2 x210 cabs and the gk1001rb2 head would make a good combo and is there anything else i should consider before getting this? would a 2x10 and a 1x15 be a better idea? what would be louder? i play a 4 string and never go tuning below a half step down
     
  2. what type of cabs?

    the two 2x10's would sound punchier, quicker, and bolder with fingerstyle and slap/funk.

    while the 2x10 + 1x15 setup would have a nice fattie feel that i like it for a great pick grinding, rockin' Pbass kinda sound.

    but that's just my tastes...
     
  4. avatar cabs. am i just better off getting a 8ohm 4x10 and getting another 2x10or4x10 down the road?
     
  5. anyone?
     
  6. Get two 210s, both 8 ohms, then just use those together normally until you get extra money. Then daisy chain the two 210s and get a 115. The 210s daisy chained will act exactly like a 410
     
  7. i know the 2x10's would be the same as a 4x10.but should i get a 4x10 8ohm and then get another 4x10 or a 1x15or1x18 to make an 8x10with more portability and i would move more air by doing this.what is your opinion about this? if you move twice as much air but keep the same wattage would the volume doubble?

    Nope. When you double your speakers, with the same wattage, you get about a 3db increase in volume.

    Let's say you've got some typical musical instrument speakers, which are fairly efficient.

    1x10 = 94db
    2x10 = 97db
    4x10 = 100db
    8x10 = 103db

    To double your volume, you need an increase of 10db.

    Same thing with wattage. Let's take the 4x10 from the previous example......

    1 watt = 100db
    2 watts = 103db
    4 watts = 106db
    8 watts = 109db
    16 watts = 112db
    32 watts = 115db
    64 watts = 118db
    128 watts = 121db
    256 watts = 123db
    512 watts = 125db
    1024 watts = 128db

    ......and so on.

    Now, even if you have an amp that is rated at 1000 watts, you have to bear in mind that you are not amplifying a pure, smooth signal (sine wave) - you've got all kinds of peaks and valleys in there that have to stay within the limits of the amp or you get distortion, so overall you're going to average pushing maybe 300 watts. That's why it's good to have headroom - extra available wattage to handle those peaks without clipping.
     
  9. so basicly by doubbling my speakers i will get a 3db increase. how much louder would that be in a live show? or would there be little to no differnce? anyone?
     
  10. when you daisy chain w 8ohm cabs together.....will it become 1 8 ohm unit, or 1 4 ohm unit
