IPL speakers finished

[Longmanjon]

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

You're first link doesn't work for me but here's one from the second:

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

[Longmanjon]

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

[oceanobsession]

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.

Looking very, very good !

I haven't played with Transmission lines but surely more stuffing would give tighter bass?

Thinking about it, maybe more stuffing is reducing the vent cross sectional area and lowering the tuning frequency? If that's the case, too much stuffing could reduce midbass and possibly lower midrange.

Sorry if this is all wrong, i'm just guessing here...

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 .

[Longmanjon]

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

[YNWaN]

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