I recently got some Eltax Evolutions dirt cheap ... ie. £100 ... and have no idea if they're "good" but they're doing fine for me at the moment as I build my HT ... busy installing an AE300 + SR4300 at present ... so please don't tell me they're considered cr@p by the cognoscenti. The speakers came without any instructions and there's a couple of things about them I can't figure out: 1) the front main speakers have two pairs of terminals with a jumper connecting one pair to the other. From experimentation they seem to feed the mid-range and tweeters respectively. WHY? What benefit is there to be able to drive these from separate power amps (which I'm assuming is the purpose)? 2) there's a switch for "phase", being '0' and '180' ... I think this is part of the bulti-in sub-woffer amp, but again can't see it's purpose. Well, obviously I know it creates an anti-phase signal, but I don't see or indeed hear what effect that has. Can someone please explain these myteries? Cheers.
