I'm sure we've all heard about the upcoming H.O. series of subs that is due to make an appearance this summer. Recently, some talk of upgrades that could be used on the VTF-3MkII, VTF-2MkII, and STF-3 subs has also been going around. Maybe we could use this thread to post new info on these products as it becomes available and, of course, to speculate. So, with that in mind......post away.
