I would love to find another VTF3 MKII to add to it but they dont make them any longer . I have found some other used subs that I would consider but they are not HSU.
Opinions please.


Really, much ado about nothing. I have FOUR subs(three different manufacturers, one down-firing, three front-firing) and as long as they have somewhat similarly capable frequency ranges(especially at the bottom end) and power, volume balanced and everything properly in phase, it will be no problem. Obviously, as we all from time to time may add or change equipment in our systems, a model we may have and like will no longer be available so when we see something we do like with similar specs and even price BUT from another manufacturer, it is quite common for this to occur. If you want something close to the HSU model you have , check the "Outlaw Audio" website, the LFM-1 Plus and EX are essentially slightly re-badged HSU models with similarly good performance but a little less costly.

Practically speaking, moving subs around to different locations in your room, even with the same manufacturer, will have a considerably greater affect than using subs from different manufacturers. Go for it.
