Hi,
I am thinking of buying this sub too and my system is similar to yours - RF52 fronts, RC52 center and S1 surrounds, driven by a Mrantz NR1601 receiver. My main reasons for considering this sub are Small size & weight, Price and frequency range (going all the way down to 22 Hz).
I am a little worried about the fact that you had to return the sub once and get a new one. I plan to buy this and ship it to India - if the sub I get turns out to be bad, then I don't think I will have an opportunty to exchange. Do you have an idea if anybody esle had the same problem as yours?
I want to get the sub mainly because, I am missing bass while watching movies (which incidentally is my main use). Can you let me know if this sub add enough bass for the movies?
Anybody esle that has an opinion on this sub - please post them here.
Cheers
