    <p>If you had to choose between these two frequency response graphs, which one
    would you prefer for your 5 string cab?</p>

    They're so similar that I wouldn't be looking at the frequency response at all. I'd be looking at the group delay and the SPL.

    Assuming equal SPL levels for the colored lines, #2. #1 only gains an itty bitty bit at the 30hz area.

    No offense, but I judge cabinets with my ears, not my eyes...

    :bag:
     
  5. By the look of the graphs, the first will have better lows, but the second one may cut through a bit more with the spike in the low mids. I'd take the second if it was based only off of those graphs.
     
  6. My guess is that #1 is in a cab that is too big for the driver with a high group delay. I would say #2 would be better, but these graphs can be very misleading!

    Someone's been playing around in winISD a bit much. In all reality though, I'm going to go with the one's who say choose with your ears :).

    OK, please go easy on me :)

    This is the blue line: http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=290-410&scqty=1

    And the Green:
    http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=299-395&scqty=1

    The box volume of the green is about 8 cu ft (32hz), the blue, quite a bit larger at 18 cu. ft(29hz).

    I see why people say to just buy premade cabs: you just don't get the same results and don't really save money. Sure I could get better results and buy a JBL driver for $300, but I might as well just buy a completed cab if I was going to spend that much. Plus I dont think I'd want to tackle building a box for a nice driver like that (I'd probably f it up).:meh:

    I'd never build a cab bigger than about 5' because I wouldn't want to carry it.

    I'd choose to use several smaller cabinets with smaller drivers, and biamp.
     
  13. Yeah those cabs would have to be monster. The really low tuning frequencies might make them a little muddy sounding too.

    Well here I am again, 3 glasses of wine and 4 beers later, and I must say thanks for all the help!, but I think I've abandoned the idea. I'll think I'll just just save and buy a nice cab, like a Behringer (jk). :)
    How is this for now? http://www.musiciansfriend.com/srs7/g=home/search/detail/base_id/110633
    Any good? or should I get a Behringer, I heard they are the best amps EVAR!!! ;)




    PS. How many smilies can you use before you are deemed slightly gay?

    Neither of those curves are particularly well suited for electric bass; both are actually far too flat into the low end, and more resemble hi-fi woofer response than what's really needed for electric bass, even 5 string. The bulk of the energy of electric bass lies in the 2nd harmonics and higher, so even for 5 string that means an f3 lower than 60 Hz is really not necessary, especially if the cabinet is sealed and has 2nd order roll off below fb and unloading of the driver is not a concern. Not that those curves are all so bad, but as you discovered the required cabinet size to get them is a bit much. And as someone noted the f3 chart is almost meaningless anyway, it's the SPL chart that counts. Flat to 31 Hz is useless if the SPL is 85dB.
