1 problem with cabs and speakers for me is that where i play can vary so much.
I can play shows where ill be pushed right up against my cab or ever stood behind my cab, thats happened once or twice. in those situations im going to struggle to hear a lot of things, which is why i prefer angled to straight cabs. it just makes things a little easier to here. thats one reason ive never really pursued orange cabs.
Roo your cab sounds like the heaviest thing ever, in musical terms i mean!
when considering speakers i looked at cost, then what i could experiment with on the cheap, then different versions of those speakers and some variants. id love to be able to get a BUNCH of speakers and break them all in and test em all out, but that would cost serious money.
SO! my current plan is this.
re-cover a cab orange, put in 2 V30's in the X setup a la Ubercab, wire it for 4ohm or 16ohm mono (since i don't use stereo ever) replaced the wires with good quality speaker wire and throw out the 1960A pcd mounted sockets and switch.
all im buying then is the V30's. I MIGHT experiment with using some diffusers, since i do find my cab as it is at the moment pretty directional. I also read somewhere that the ubercab has some 'poly-fibre batting' in the back of it. not sure how that effects ubercab tone. ive never played an ubercab but from what i understand it has a good reputation.
Dave, the range of sounds seems even better than the first 5881 Avenger i had! maybe thats psychological, but id like to think it isn't!
haha
