If the driver your using is heavy like the Maelstrom or Tumult then YES definitely use some all-thread rod, the wax coating on the inside prevents a good adhesion of any kind of sealant. For the lighter smaller Sonotubes this probably wont be a problem, but with mine having a double thick bottom plug plus the outer layer and the driver weight there is no way a sealant would hold properly, also a extra heavy bottom will make the sub much more stable and will not walk across a hardwood floor as some have experienced. Another added benefit is the threaded rod sticking out the bottom makes a good place to screw on some feet.
