Eh, that's not exactly it. It is certainly capable of going well above that, of course. It isn't exactly the most "articulate" or "musical" sounding thing - it isn't designed to be. It does one thing and one thing only... LOWS! So, while it is certainly CAPABLE of going much higher, you're likely going to set the crossover point somewhere around 75Hz, depending on your upper speakers if you're using only the TubaHT.
My original idea when doing the sub experimenting (an I idea I still might implement in this impending church project) is to incorporate two subs. The CSC Trio12 BIB is GREAT at 32Hz and above. I might use it as the sub for all of the 16' stops and leave the TubaHT to handle the 32-16Hz range (that is to say 32' stops) only. This is largely due to the articulation differences between the two sub designs. The TubaHT is a 15" driver, with a LONG horn to traverse, at very low frequencies. Therefore, you can't really expect a good articulation out of it. It will just give you a solid fundamental and a few overtones. But the CSC Trio12 BIB is an altogether different design. It's a resonator pipe-type of thing which has the 12" driver mounted in the bezel (face) like any other speaker cab, but utilizes the horn off the back side of the driver. This sub has a nice quick, responsive attack. I like that.
Sorry.... I kind of went on a tangent.....
