    So I was checking the specs of my current AV amp and speakers (see sig for details) to see if my planned purchases were going to work ok, and I came across something that just doesn't make sense to me at all!

    The satellites only extend to 140Hz and the amp redirects frequencies below 90Hz to the sub out when speakers are set to small (as they are in my case).

    So surely this means I'm missing out on the gap between 90 and 140Hz?? Is that right or have I totally misunderstood this?!?

    If you satellites only go down to 140Hz then you are quite correct in your assumptions. 140Hz is a very poor lower frequency response, even for a satellite speaker, I would look at getting something better immediately.

    I had the same issue when i had those speakers and the RXV540 receiver.
    In the end i set the front satellite speakers to 'Large'(this bypassed the amps fixed 90Hz crossover), with the sub woofer connected via its high level input. I then set the crossover on the sub to rolloff frequency of the sats (approx 140Hz iirc) this setup worked OK for me since i didn't need to turn the volume on the amp up too loud so the stellites were in no danger of getting damaged.

    so what on earth are yamaha thinking pairing the two together in a kit?!?

    what I also don't understand is how I can't hear any obvious gaps during a frequency sweep - maybe the specs are just inaccurate? did you find the same donagon?

    Ah well, more reasons why I should get the AE Evo pack for christmas! :clap:

    Sounds like a good idea to me :devil:

    Happy Xmas

    hey dfour - did you ever think of using the compacts as rears?

    I did but I already had the excellant Eltax HT2's so ignored the idea. I also have to have my sofa hard up against a wall so i thought the bi-polars would be better and im trying to stop my run away spending:nono:

    If you have a cut off frequency of 90Hz it means that 90Hz is the point at which the output will start to fall below about -3db. How fast it falls depends on how good the crossover is (the better the crossover the faster it will drop). A good crossover will stop as much of the unwanted frequencies passing as possible (90Hz and above in this case). Even the best crossovers will still allow some frequencies to pass. For example you might be getting -3db at 90hz, -6db at 100hz, -9db at 110hz, -12db at 120hz and so on.
