Those Traces were pretty common in backlines around here for a little while. Don't have much experience with them but the few times I did, yeah, huge girth and "balls" for what you'd think of as 250 watts. I might be inclned to get one for a something different and totally gig capable amp, although, with the 800rb (one of my favorites) you absolutely can't go wrong. I really liked my SWR sm400s, but some other swr's, not so much. A couple of the smaller ones, California Blond, Baby Blue, etc. were just great.
