    Default IPL speakers finished

    For third time I’ve built a pair of IPL acoustics speakers, I think I like the build process too much.
    Anyway these are the s2tlk ones, which this time I have finished with zebrano veneer and some chord odyssey internal wiring
    I expect i shall fail though with uploading the pictures

    Looking great mate , yes making speakers can be very addictive and time consuming but worth it , I used the chord rumour , you can solder very close

    without any damage to the insulation , did it take you long to get the stuffing right . phil

    Thanks Phil, by stuffing do you mean the soundproof foam or the wool? I just used the amount of wool recommended by Ivan and It seems good so far.
    One thing I’m not sure about is the spacers I used between the plinths and bottom, currently just plastic spacer I wonder if something softer would be better

    Also I’m wondering if the yellow driver cones are ok or maybe go black again

    A yellow cone usually implies it is woven Kevlar. Going to a black cone will therefore mean changing the cone material and therefore the sound.

    Nice veneer .

    Yes sorry I didn’t mean changing cones, last time I coloured the cone black with permanent marker as a previous builder had done the same and there is no damage to the cone

    Yes I meant the wool in transmission line , you can stuff the line to suit your room size , more stuffing better bass but to much gets boomy , it takes time playing around , im sure you can probably adjust tweeter attenuation aswell with a resister change , you could try soft rubber washers between the plinths . phil.

    I think the cones would look better black - but I guess you already know that . PersonLly I wouldn’t change the plinth spacers.

    im still playing around with the IPL, but to me they seem to miss a bit in the lower midrange occasionally. to me it seems like they need more power as when I have the volume up it seems to allow more overall quality.

    I am currently using a naim atom, which is rated as 40w although Naim under value their specs.

    im wondering if I should try something a bit more powerful, but not sure what would be adequate and if there is something which is not too expensive to try out?
