    Hi can someone explain this to me as im a bit lost.
    Ive just got the above amp, now for the 6-1 films on dvd a back speaker is needed so ive got a pair of polk 3001s, (to be wired up as one speaker) anyway i think they are 8 ohms, so the 2 would be 16 ohms load, now this amp has a switch at the back for this so i should have no problems (also the review in June 2000 home cinema says do this)
    But will this affect the operation of my other speakers ?
    Will my other speakers work ok as i dont know there ohms ?
    As ive got to switch this switch to the 8 ohms upwards setting for this new middle speaker as its load is 16 ohms now, surley some of my other speakers possibly wont run correctly if they are say 4 ohms ?
    My other speakers are a pair of definitive bb8s at the front and the centre to go with them and another pair of polks (lfsxs) at the sides.
    Any help would be great.

    Don't worry too much about impedances of speakers.
    The quoted figures are 'supposed' to be an average load, however, in reality a speaker will swing from 1-2 ohms right through to 10+ constantly as it goes through the frequencies.
    Just try them and see if it sounds ok.
    Unless your speakers are truely 'double hard bast***s' you'll be ok. [​IMG]
    The worst is the amp will strugle at very high volume, ie, hard work.
    So plug 'em in and let rip. [​IMG]

    Douch!!......Wot's da madder, da CIA got you pushing too many penzils?
