Ok...
A Pair of Subs (Pairs have advantages) is a costly, albeit Wonderful proposition!
I think it best to direct you to SVS (US) for specific guidance. Specifically, I'll ask you to communicate with Ed Mullen:
edm@svsound.com
He's the Chief of Engineering, and would be most qualified to discuss sales in your Country, Product choices, and implementation. I will say from first-hand experiences, that Ed is a Walking, Talking Repository of Acoustic/Technical Knowledge!!
No Audiophile BS.
It costs nothing to ask!
Best!

*If I can extend my Sermon just a bit further...
Like RME, one of the BEST advantages SVS offers, is the Customer's easy access to Expert Technical Guidance, and Product Support! This is Valuable, as the most amazing Sub on Earth can make you VERY SAD if poorly implemented in a Room.
I've had my SVSs almost 10yrs, and have never had a moments regret. How's that?
