I have a Peavey 4x10 sitting on top of an Avatar 1x15. I'd like to replace the PV with something better. My concern is that the delta 4x10 does not dip as low into the frequency range to produce my downtuned bass setup (CGCF) as compared to the neo and kappa. However I already have a 1x15 and I don't ever plan on just bringing just one cab with me so I don't need to worry about how they work by themselves. If I get the 4x10 delta will the higher notes naturally go into the 10's and the lows into the 15 or will I hurt the 4x10? I'm hoping I can pick up the 4x10 on ebay (I've only ever seen the Delta's on ebay, which is where my dilemma arises) and save some scratch as I am a college student and a few hundred here and there can be a big deal. (I play heavy metal, I have an Ampeg B-4R, I'd rather run it bridged so I have more power, as I have two half stack guitarists (both have 120 watt all tube heads), an extremely loud drummer, and a loud singer to run against.) Thank you.
