I believe Ultra's four tuning frequencies/settings go without saying. The "PB12-NSD new" is the latest revision of this model. Performance of the new PB13-Ultra in all settings, but especially in 20 Hz and 15 Hz, is very convincing. From all the subwoofers I have tested thus far (using the CEA-2010 test), in addition to the JL Audio Fathom f113, the new Ultra is the only commercial subwoofer that can even slightly tremble the "top 10" ruled by the all mighty DIY subwoofers.
Pictures from today (starting from #93)
Yes, I was able to blow the internal main fuse of the PB13-Ultra - twice.
It didn't seem to like my 30 second long sine sweeps at extreme levels (I was expecting this based on AV Talk's measurements though). More dynamic signals like the CEA-2010 bursts didn't cause any troubles, even at extreme levels. It shouldn't be possible to blow the fuse using regular program material. This "problem" doesn't have anything to do with the other PB13-Ultra amp problem (shut-down due to bad batch of components combined with sagging 110 V voltage). There are no reports of shutting down 230 V versions of the new Ultra.
