I've only tried the Traveler 151P. I have two of them along with a Little Mark III head. I believe they do well enough on the lows, and they have a mid thing going on (that is they are more middy than my 121H combo's cab, seems like---I think?). Anyway, they are quite resilient and can take plenty of volume, especially when run as a pair at 500w. I usually only use just one, though, for most gigs. But, I do use them as a pair fairly often as well. I can't say much for the piezo tweeter, but I'm not really putting out enough highs, seeing that I'm running flats and going for a more old school sound (from a Markbass? I know, I know...but it'll do it).
If I had it to do over again, I'd pick two of the New York Randy Jackson cabs. Nothing but great reviews on that model. I bet the Standard HR would kick the most butt, though, if you wouldn't mind hauling it.
I thought my 151Ps weighed 37.3 lbs. at first. That was the listed weight. Come to find out they weigh more. When I kept noticing it on my home scale I contacted Peter Murray, who in turn contacted the company in Italy, and was told it was a mistake left over from when they redesigned the cab in 2007. The weight figure didn't get changed. So, now it reads 45.75 lbs., which is more than I actually wanted.
Hard to find reviews on the Club stuff, at least it was for me. I'd like to try one.
GASing for a Barefaced stack now.
