Hi all, I have the opportunity to buy a new Tannoy Mercury Sub 10 for 125 pounds/250 euro at a store. First of all i would like to know if this Sub is any good? It's part of tannoy mercury line.(t's budget line so to speak.) How does it perform? Will it be a good choice to combine with my KEF Q 50/Q10 and ref 100 center speaker? I was interested in the yamaha 320 or maybe even a RELq50.But these are nearly twice the price. While the Relq100 is nearly triple it's price. So for a first time Sub, this is very interesting. So i hope you can help me out. I have to make the decision by monday. So i would appreciate it if you could place your reviews of this Sub on this board asap. Like what's it's strengths and weaknesses. How to set it up etc.
