I never liked the sound of the unmodified second generation Model T for bass. Too midrangey for my taste. Since I've done a couple of mods on mine, I like it very much. However, even through one Model 215 and one Model 410H, it's marginal for loud gigs. When everything else in the band is miced, it gets well into distortion. Some like that, but it's not my preferred sound for bass. Of course, the Model T can go down to 2 ohms, so I could have used two 215's and two 410's, if I had them. That might have been enough...
