I have at the moment a Yamaha HTIB-45 Home cinema package
as seen on here
Would it be worth changing the speakers for a difference sub 100quid set?
, would the change be noticable? note i would still be using the woofer from the yammy package.
I agree with buns that it is at most a sideways step. The HTIB is a reasonable performer for the size and price and you would need to spend more than £100 to hear much of an improvement
