WakeWorld - KMT6 or Single Skylon Deafcon IV

I Bought a single Skylon deafcon IV on ebay and i'm trying to decide if i should keep it or sell it and get the Kicker KMT6.

There are 3 real issues and here they are in the order of importance.

Cost:

Because I already own the deafcon it would be the cheaper route unless i could sell it for the same cost of getting the KMT6

Performance:

Which of these choices will produce better music to the rider?

Aesthetics:

I would only have a single deafcon probably run right in the center of my tower. I know this will probably look goofy so the KMT6 obviously wins here.

Your thoughts and input would be greatly appreciated
