I am looking for a sub for my cinema system, where although music is played quite alot movies are the main use of the system. I have a kenwood DVF 9010 dvd kenwood V7771D amp tannoy M3 frts tannoy MC centre tannoy M1 rs I was impressed with the review of the vibe alpha active sub in mays hcc, but being as i have all tannoy speakers would it not be best to get the tannoy mxsub10. Any other subs worth looking at in this price range or is one sub as good as another in this price range. When i tested the speakers at my local av shop the speakers were set up with an B&W £800 sub,i can't afford that so advice will be much appreciated. Thanks Spider.
