    ?

    Hi Zilch ,

    i guess that means horn response ... so i need to look at the spec of the driver and decide what I want it to do ... in very basic terms the horn controls the frequency response of the driver ... I would like to keep the range with 45-50 htz to 4-5 khtz a use 075 or 035 to extend hf and something below to get down to 30 htz .

    am I on the right track - I can design a horn to do this ?

    I'm a complete novice as an EE,but the construction is no problem atall.


    thanks ,Rich

    not so easy

    See the website of D.B.Keele for a paper about how to calculate a horn's ***theoretical*** performance from the Thiele Small parameters.

    The frequency response of the LE8T gets irregular above 1 kHz or so, a horn cannot improve that.

    Without a phase plug the horn's ***practical*** frequency response will suffer from destructive interference.

    Zilch refer's to the software found here: http://www.dmcbean.bigblog.com.au/index.do

    I haven't actually looked up the LE8 T data, but you need an insane amount of motor to get a meaningful HF response from a cone driver.

    Anyway - download the hornresp software and start playing...
