Thread: WHY are high-efficiency speakers are better at conveying emotion of music vs. audiophile vocabulary?

    This paper was back both by the mathematics and actual comparative measurements, seems the science/arguments/hypothesis were more advanced in the 1960s and 1970s than now Lol
    I have owned a lot of Klipsch stuff over the years but material science used in modern speakers has come a long, long way since Paul's days.

    I get phasemeasurments automatically added when i design ls.
    I hardly look at the graph , not important for designing imo.
    Its more of a end result by productgraph.

    Agreed. I would not compromise SQ for efficiency in a design but I would certainly match the amplification with an understanding of both impedance and angle across FR.

    Efficiency is determined mostly by the type of units that are used, further by way they are connected/ type of x over.
    High efficiency and impedance are design goals , phasebehavior not.
    I find it important that a speaker is easy to drive to give IT a jump factor and to widen the Amplifier choice.
    I currently listen to a 10 watt class A SS poweramp , and i miss nothing

    PS i could design higher efficiency speakers of the same size, using Thiel accuton for example, but i prefer different softer tonecolour for the mids.
    100 db eff for a cone design sure is possible.
    10 watt SET aint 10 watt SS Though with set you lose bigwoofergrip.
    Electronic / house music and dynamic Movies make that easily obvious.
    With a cost no object design suited for a bigger room i. Could go 100 db eff .even with papermids That would blow the socks of the Wilson Wamm easy lol.
    It would be a 2 towerdesign completely passive, dont wanna miss out on using big tubes on the basstowers.
    You only need one. Amp in my designs though lol , i like to keep it affordable/ simple, that one would probably be even easier to drive then the XPE design


    PS i could also design a Thiel accuton 80 db speaker , the brand alone doesnt mean ****

    There are some insensitive drivers (thin electrotstatic drivers like in the STAX ELSF81) that can achieve the same subtlety but not heavy conventional drivers, IMO.
