    speaker stands?

    well you calculated that figure for each cone excursion no? So more cone excursions means more distance moved on average.

    speaker stands?

    yep. For every cone excursion. But over time it accumulates.

    speaker stands?

    where have you taken into account the mass of the whole speaker in your calculations (which can only be a simplification by the way. I dont know how accurate your calculations are)? and what are the other symbols you are using? If you want to explain it, you had better do a good job of it or...

    speaker stands?

    No i havent heard of him but read what the previous poster wrote: Get an explanation how this happens. What is the threshold of movement that is audible with music in a listening room. Good luck. Can you see he doesnt seem to agree with what you say? Yes the cone motion creates a force but...

    speaker stands?

    if your read what someone wrote before you, you will see it is not consistent with what you write. So where is the evidence? One person says there is no difference and its all snake oil. You believe differently. Whats the truth?

    speaker stands?

    There is also the claim that stands remove cabinet vibrations and dampen them which then affects what you hear. This does not seem unreasonable and requires investigation to ascertain the truth.

    speaker stands?

    Its often reported that higher mass stands give you extra bass extension. Its not physically possible to lower the bass extension but it is perceived to happen and requires investigation as to what could cause such a perception. The stands often are fillable with sand too to experiment with the...

    speaker stands?

    Partington Heavi review from the experts at whathifi.com heres a quote from a review of a high quality stand: As soon as your speakers hit these stands, the Partington signature is obvious: bags of headroom, a solid soundstage, warmth and detail in the midrange, and deep bass sure to get your...

    speaker stands?

    So all the hifi reviews are wrong and people that buy special stands are being fooled are they? There are high mass stands which seem to affect the bass response. How? Better stands may keep the speaker more still also affecting the sound. I dont know how it all works and that is what I am...

    What do you mean that no recordings are not phase coherent? Lets define what you mean by phase coherent first.

    phase accurate speakers?

    The question is why are there so many different cables on the market with such a wide range of prices? Is it really so difficult to make a cable which does not act as a filter? For it to act as a filter it would need to possess a lot of capacitance and inductance which most short cables do not...

    phase accurate speakers?

    I'm surprised to hear you saying that cables even have a sound. I think I remember you saying in another thread that all cables are essentially the same. Isnt that what you used to believe?

    phase accurate speakers?

    Is there such thing as phase accurate speakers? Which ones can I choose from? I have heard the egg shaped speakers from eclipse which sounded pretty good. The imaging in particular was very precise. They are one of few companies producing such speakers.

    My question is how can you say you have no time when you have already spent a very long time and effort in writing responses on here and on your own website? Can you understand why I feel cheated and why this seems evasive? On one hand you are a proponent of time coherence and go to great...

    No this attitude is not right Roy. Firstly why cant it be self taught? Secondly you keep speaking of the mathematics yet you have never presented any math evidence for the claims. There are mathematicians on this very site so do not be afraid to present it. This sounds condescending to claim...

    Check out the frequency response of these

    If you had been paying attention in your other thread, Roy Johnson pointed out that the trouble with response curves is that it very much depends on how you take the measurement. Moreover our ears 'ignore' all the reflections whereas a microphone will not.

    Green Mountain Audio Europas

    You're right Jerry this is beginning to sound as though those 10 year old Europas are never being blamed for what you're hearing. This implies they are flawless. I don't feel comfortable with that. Is Roy willing to accept the possibility that those speakers are quite simply flawed...
