Hey thanks for all the replies. I like the sound of the Tempesta / TC12 combo. Two things that come to mind when I think about a setup like this would be the connectivity options I have to the sub and the current power capabilities of my Pass x250 amp feeding the Tempesta's.
In terms of connectivity I use a BEL Canto DAC3 as a DAC/Pre which has XLR and RCA outputs. Currently I am running XLR to my Pass amp and do not use the RCA's. Taking the distance of the speakers into account my first thought would be that I may need to consider using XLR to feed the Sub portion and then use RCA to feed the Pass but I'm not sure if the Bel Canto can output signal to both at the same time.
My understanding is that long runs of RCA can be prone to potential noise issues entering the signal path given the 15' run that I would require to feed the signal to the Subs. Can an XLR Input be integrated into the TC/12 Sub portion?
Regarding the Tempesta's, I see that they are rated to handle up to 150w of power. Since the speakers are 4ohm that would mean my current amp would be jamming roughly 500w of juice down on them; if not more knowing how Pass amps are notorious for being under rated in terms of power output.
Now I usually like feeding a bit more power to a speaker then its RMS rating but this may be really pushing it unless the Tempesta can be setup in an 8ohm configuration instead of a 4ohm.
Is it safe to assume that the Visionario speaker wouldn't be a good fit in my configuration due to the rear firing port, or any port for that matter. The specs seem like a good fit showing a healthy dose of bass extension.
Rick, your recommendation of having the Tempesta mounted ontop of the TC/12 had me interested in seeing what this configuration may look like so after looking at the Gallery you have I found the picture linked below. I'm guessing this would be very close to what that configuration would look like.

Thanks again for any additional info you can provide
