Thiel cs2.4 upgrade to cs 2.4 se

Hi.

I'm new here..

Pieter from Germany.. ( Dutch, not German)

I have a, not yet fully operational, surround system with Atmos with only Thiel speakers.

Four SCS 2.3 shielded units; two with Mundorf caps and coils, two with clarity Mr various and Mundorf copper foil coils. These work great.

I have five onder SCS units; one for the center, which will also be made with clarity caps and foil coils, the other four (Atmos) will be made with Mundorf coils and caps.

I have one Thiel TSW 12.1 which needs a cabinet of 100 liters. I have a unit to drive it.. but this needs testing.

And then I have two SCS 2.4 which need to be upgraded to SE.

One of them is less open and I'm hoping this is due to a faulty electronics or writing and not a problem with the mid/high unit. This problem had been there since I've had them. Two years ago I blew this unit up during room correction with live Dirac.

Rob Gillum fixed this for me and I'm now in conversation about the SCS and the cs2.4.. 

Any suggestions from you is welcome.. Any suggestion on the best resistances, besides coils and caps?

I'll post some pics in the future..

Have a nice weekend

Pieter

Just as an aside..

I had the 2.4's up for sale in eBay for a couple of days and decided to keep them and go for the upgrade...

I don't expect to be disappointed

@holco 

Do you have a list of all components you put in your Thiel 2.4?

I'm going for an upgrade and was planning on Jantzen just like you with also flat coils.. you seem to be pleased with your setup..

Greetings,

Pieter

I'm looking at coils at the moment and was wondering..

If I want a coil with 0,10 mH, I have the coice (Mundorf) between CFC 14, 16, 18 etc. 

These all habe same value mH, but different Ohm-values.. In the end I need to come to 30-31 Ohms on the mid/tweeter of the 2.4.. how much would the wrong coil distort.. Also, I don´t really know if the CFC stands for the same as AWG/ gauge... lower AWG means thicker copper strand, higher CFC means bigger coil.. (maybe ill get in touch with mundorf in germany... )

cheers

I hope nobody minds me posting all these messages without waiting for a response...

I'm most probably going to do the mid and high section first, maybe also the bass..

If I combine capacitors, which can't really be avoided, would it matter much (and if yes, in what way) if I combine a 10 and a 3,9 uF to make (almost) 14 uF our of I combine a 13 and a1 uF?

I'm looking at the Jantzen amber or alumen.. the amber is pretty expensive.. maybe buy two of these in 1 uF and a 3.9uF 600V Miflex KPAL-01 Aluminium Foil Paper / Polypropylene in Oil Capacitor or audyn true copper also both a very good rating, not so expensive.. 

Our would you say it would be better to keep these small capacitors from the same brand? As I most probably will have the larger ones either Jantzen or Mundorf.. 

It's like standing in front of the milk cartons.. thousands of choices, which don't make it any easier 😉
