    JBL 4412 + Yamaha MX-2 = 2Bad ?

    Hello .

    I have Yamaha CX-2 and Yamaha MX-2 and speakers are JBL 4412.
    When I play music low it is allright , but when I am playing loud ( not clipping)
    the sound get screeming.. ?
    With my old speakers , a pair of Jamo , cheap danish speakers, it was not screeming ? Is MX-2 a bad amplifier or is JBL4412 a bad speaker ?
    Anybody seen a rewiev of MX-2 ? I only can find one rewiev (Audiorewiev).
    Is it just a bad combination of speaker and amplifier I got ?..What to do ?

    Best Regards from Denmark.

    It would be hard to call the 4412 a "bad" monitor since it is one of JBL's most well regarded 12" 3-way designs.

    Not sure exactly what you mean by screaming though... the 4412 is very neutral and transparent. It's response is pretty much flat under a number of load scenarios.

    I'd say it's the amp, but that's just me. More info?

    It sounds like the yamaha MX-2 have a hard time. Is 4412 a hard speaker for the amplifier? Impedance ans so on ?
    Where can I see how 4412 is doing on impedance over the hole freqence ?
    Hope you understand and sorry my bad english.

    Not particularly, no. I've never heard of anyone having difficulty running 4412's.

    [Though I do vaguely recall it being mentioned before.]

    Try 'em on a different amp, maybe....

    No, I'd say the amp should work fine... more power would not be a bad idea though. Something stable at 4ohm loads with say 80-100 clean watts?

    The components in that monitor can be driven quite easily with far less.

    Does the amp you are using have nay known issues?

    The amp I am using is Yamaha MX-2 2 x 190watt RMS 4 Ohm.
    Maybe something about Yamaha is not working very well with the JBL4412?

    Hi Fritz
    May I suggest you beg borrow or steal a "CD Player" and plug that into the system and do an AB comparison,I think you may be suprised!

    Anybody know where I can find a test or some words about how a
    Sony dvdplayer NS930 sounds like ?
    If the Sony is bad in stereo I will recone the 4412. So they will last another 20 years !
    I tried the internet .I cant find any test of that dvd player..

    Fritz

    PS: THANKS for all your help. I need it badly.
