    Eqiupment.

    Pioneer VSXD2001 amp with Morduant Short THX speakers.
    The instructions for my amp say that i should use speakers with
    an impedance of 8 ohms or greater. The speakers are rated for
    the front speakers at 4 ohms , does this mean that the amp is
    not compatible with the speakers , please help i spent all my money

    Hi paul
    Iam sure a pioneer owner will give you your answer soon,from what ive read on these forums all that will happen is your amp will shut down at high volumes it wont damage your speakers or amp- you then reastart your amp and all will work fine.The only way that you could damage the speakers is if you run the amp so loud it clips this will damage the speakers,so as long as your sensible with the volume you should be ok.

    I phoned Pioneer about some other speakers(namely M&K K4 rears) and about their 4 Ohm rating.The reply which I got said that , I should NOT use any 4 Ohm rated speakers at all as they would overload the amp(and I to have a 2011) and this would invalidate the amps warranty :(
    Please by all means ring them yourself and see what answer you get as I would be interested what they say to another person.I know this is very disapointing, just think of it this way, AV is a learning curve for most of us, and I now know to buy an amp that can go to 4 Ohms the next time I get one.
    I hope I haven't been the bringer of bad tidings. ;)

    I can hopefully be the bearer of better ones. We have been using a 2011 (along with a couple of other amps) down at the test facility with the THX bits and bobs for nearly a year. The 506 dipoles are rated at 4ohms but are at least sufficiently sensitive to avoid any amp trauma. Gonzo is correct that the amp will cut eventually but ours has only ever done this once (after an age at reference level). Unless you're a member of spinal tap, I can't see you doing either of the components any harm.

    Paul i am not sure if you have got them or whatever but i was in exactly the same position a few mnths ago.
    The amp and speakers will be fine they are 4-8 ohms rated so your amp will be fine, i have used mine at reference level for a whole 3 hours and it hasn never overheated/turned itself off.
    I also called Pioneer and they gave me a big no but i went through with it and all is well
    Regards
    Fred

    When you set up the amp did you change the impedance level or did you keep it at 8-16 ohms

    thanks again

    no i didn't change it, leave it at 8 ohms. But make sure that the amp has space around it, ie don't put any equipment on it or anything, my 2011 has got very hot on occasions when i put my dvd player on top of it but was fine once it had space around it.
