    I was wondering if anybody knows anything about the kef model speakers. My friend has a set of kef model 107 speakers that he got from his dad and i was just wondering if they are pretty good speakers or if they are not so good.

    thanks.

    I don't know that model but Kefs are great speakers. They are british made. Apparently, model 107 was produced in the 80's. Here is what I got from Kef's website, hope it helps :

    Frequency Response
    20Hz - 20kHz +/- 2dB at 2m on reference axis

    Directional Characteristics
    Within 2dB of response on reference axis up to 15kHz for +/-10° vertically, up to 10kHz for +/-30° horizontally

    Maximum Output
    112dB spl on programme peaks under typical listening conditions

    Enclosure Volumes
    Low frequency enclosure: 72 litres. MF/HF enclosure: 8.5 litres

    Amplifier Requirements
    Suitable for use with amplifiers capable of providing between 50 and 300W into 4 ohms resistive load.

    Nominal Impedance
    4 ohms resistive from 20-20,000Hz

    Characteristic Sensitivity Level
    90dB spl at 1m on reference axis for pink noise input of 2.83 V rms, band limited 50-20kHz (anechoic conditions)

    Weight
    45 kg (99 lb)

    Dimensions
    1165 x 330 x 448 mm
    45.9" x 13" x 17.6"

    Height of Origin of Reference Axis
    1020mm (40") above base of cabinet (not including feet).

    Angle of Reference
    = 1.5° from horizontal

    I'm currently using Kef reference speakers. They are just a pleasure to listen to. They can appear overly bright with certain gear, ie sony normal line(not es). I use Integra (neutral sounding). When I bought mine, I compared them to Energy Veritas, Sonus Faber Grand Piano and B&W line (not nautilus). I'm not that familiar with your model, but there is a fun test to try that my dealer showed me. If you stand a nickel on edge while playing this speaker even at reference levels, the nickel will not fall over. That is an indication that the cabinet is not coloring the sound with resonations. Enjoy.
