Hi There,
I have a pair of Buttkickers bolted to my 5 chair two tier riser and they are excelent. The LFE's and the BK amp can be had for almost silly money if your in the states, certainly compaired to when they first came out. They can really add to an action movie in the same way that a sub can. You can stop trying to hit silly lows with a sub as to be honest shifting air to shift mass is not particularly effcient. They will allow you to run the sub lower with more headroom and get a greater effect. They made AvP worth watching....a sudden LFE effect at a quiet point and you jump.
If you watch a load of Rom-coms or chick flicks then....what are you doing here
I wouldn't bother with the aura ones, i had an interactor vest that i pulled apart to play with, they are more like a joke handbuzzer !
I have a pair of TT's that i will one day wire up and play with, they are also suposidly good, but the BK i'd say is king.
Cya,
Lee
