With regards Coustic components;
Have a read
HERE , interesting thread started by a current iasca judge.....
You shouldn't judge a product on price alone.....
It's 90% installation 10% kit.....
40% installation, 40% setup, 20% kit imo!
To be honest mate, no-one on here can tell you that ANY speaker is rubbish.
If you like the sound of it then thats what you like. Just becuase some random guys off the internet didnt like it doesnt mean you wont either. Doesnt matter weather its a £30 speaker or a £300 speaker, That the thing with audio, its all personal preference. If your ears like that sound then who cares what speaker it is or who makes it.
Try n get along to an audio shop (even halfrauds) and listen to the speakers on the walls.
Get a nice simple track and listen to it for a few seconds (10-15max) on each set of speakers, listen to one part of that track, eg the vocal part. and then you'l hear the diffrences.
i did this and was amazed at how different some speaker sound back to back.
Dont bother with the rears at all. Concentrate your efforts on the front.
