10" Visonik question

[clutch1]

I was at Walmart today and walked past a shelf full of those crappy Walmart subs, but I noticed some Visonik ones (which is what I have now.. lol).
There were these "bass packages" with a 10", sealed box, and small amp, all for $50.
Visoniks are decent for the price from what I've found in mine.. would it be worth it picking a couple of these ups to add a little tighter bass combined with my 12" Visoniks or perhaps put in my room to add a little bass there?

$50 seemed pretty cheap to me, so I figured I'd look into it a bit more.
