Ok, I need a small 4ohm cab to get the most out of my early 90's SWR 350 red face, the full 350 watts @4ohm. I just got a 6 string bass and with the low B Im thinking that my setup, after some testing at home (the 350 @ 225watts into a 8ohm 2x10 avatar kappa pro), is not able to project the B without some breakup or clipping the amp at higher volumes. Normally its fine with any of my 4 string basses, but this is my 1st B string bass and I see how they can really push your amp to the limits. Im using this setup in a funk band with a drummer, keys, guitar, and will be adding more instruments as we get our set more and more together. So, Ive got another matching avatar cab and a 2000rb head but I would rather make use of the lighter SWR head and one small cab for inside medium venues. I'd like to get an avatar 1x12 delta 4ohm or another 2x10 in a 4ohm version, which is best for a low B? My other option is that I have an old ADA bassline 2x10 cab that I could replace the speakers with 2 8ohm speakers for a 4ohm cab, but what Im wondering is that the cab may not be tuned for this? Although its a pretty solid built cab. I dont have the money for iamp 800 combo yet, so Im trying to keep the cost/weight down a bit until I can afford a full upgrade, but still would like to get the most out of my SWR for now.
