I know Randall is not noted for its bass gear, but I had an opportunity to try out the RB500 head with the RB810XLT cabinet last night, in a local music store I had not been to before. Since I was the only person in the store that evening, I was able to pull the cabinet out from the wall and move it nearer to the centre of the room. I was quite pleased with the sound capabilities. I tried 2 different basses through the rig, both 5 strings (an offshore Spector and MTD). Lots of lowend (ported cabinet, overall 'feel' reminded me of the Peavey TVX offerings), and the tweeter was not too overbearing. I can't find any specs on this stuff, even on the Randall website (like weight, for instance). Pricing was in the mid-range end of things, with the head being $799 and the cabinet $859. Seemed fair, given what I experienced in a half-hour test run. I'm not in the market for a rig like this, but it struck me as potentially good value for rock/metal. Anyone use a setup like this?
