Apart from the association they have with chavs........ They are large (generally cheap) speakers and generally produce flappy farty distorted bass, the only exception being proper Genesis 6x9 subs. Other than that, they play treble, bringing the soundstage backwards. Do you go to a concert and stand with your back to the stage? No - so thats why the mids and treble come from the front and the (unidirectional) bass comes from the back. Scort - Mutant are average, just like any other chep brand of amp, I would stick with a proper make and look at decent 2nd hand stuff to fit within the budget (plus you get better SQ and higher real power generally). Sorry to be picky, but you say your £45 speakers are a bargain but you havnt heard them? I would assume they wont be as good as the infinitys, thats why theyre cheaper - not really a bargain. In ICE, as with anything, you get what you pay for. Woogie, dont worry about sticking with 1 brand - I would personally prefer to stick with a specialist brand for each item e.g. RE for subs & speakers then Stinger for cabling etc. Also, always quote the RMS power, not the Max - as it is meaningless.
