I have just purchased 3 QS-4's and a VP150. I allready have 4 subs. Given the choice of either of the above which would you choose and why. Thanks

What exactly are you asking....???? You made the purchases, so what do you want us to say??

I have not purchased the mains yet. Looking for opinions on the mains. Thanks

if you al ready have 4 sub bass is not a problem at all so I would go with the 50s for the added out put.
