Did you get all your parts?
It is maybe too late to answer your questions but, it is an opportunity to share our impressions.
I've built the Faital 3WC-10 one month ago and I'm using them with 2 SE monoblocks of 20w each (and tested with UcD 180 w).
It is not my first "TG's" built and I previously owned Cornscala (just before).
However I can not compared to the 3WC-12.
TG described them as "Dynamic and with a degree of 3-dimensionality".
Coming from Cornscala, the dynamic did not impressed me that much (apples and oranges, sorry). 3D is very dependant on the placement and I did not spend much time for that.
Im my room, these speakers are very "pleasant". They don't do anything wrong. Easy listenning, for every kind of music. Transparent but not agressive at all. The highs are "polite". I do not have the Be dome by the way.
If I could tune something, it would be the transient attack. It has not the punch that you could expect for that amount of money. Not fast enough IMO.
Maybe the 12" or the 15" are doing better. If I could start again, I'll go for the 12" or even the 15" if you have enough room.
But, do not get me wrong, they are excellent speakers.

You can cheat a little with 0.1 uF bypass on c5, or even change c5 (too much smooth maybe for that low pass second order area reading at your feeling) with a Solen (cheap but good here , also with the 0.1 MIT RTX). I would try to bypass the bass standard Jantzen with a MIT RTX first... Not expensive related to the price of that speaker !

What resistors are you using in the tweeter circuit.makes significant difference. Be bold use the mundorf 30 watt m resist ultra foil resistors.worth every penny and yes there sre pricey. Who said good sound comes cheap.good luck and enjoy.

you can use the Powertron bulk that is the same but the copper coating if saving monney is important, think they sound the same. Hifi collective have them, that said with the Brexit and import fees based on where you live, the Mundorf may cost the same.

the Faital has been said to have better bass than the Yam. the Be domes and tweet of the Yam should be more resolving and a different soundstage feeling as it is has a mid dome. Hard to know without having heard them. The 3wc-10 may be short in the low-end according the room and tastes. For me, a PA 10" is aking a 15" below ! 🙂. A 12" may suffice - see OSMC thread here - Mezzo Calapamos - 3wc-12 you talked. You can increase the Faital 12PR320 to 105 to 117 L to have a little more low end as well. I planned something similar to stay 3 ways : see the OSMC floorstander evolution thread (105L). Construct it as the Nova Andromeda to permit yourself evolutions.

Also the last 12" BMS + Textreme could be a little better too and as the Faital proce made x2 in few years it is not anymore une bonne affaire, imho !

But just my 2 cents, one has to listen to a loudspeaker , not the datasheets, so take it with a grain of salt... If you have an active sub, the 3wc-10 maybe better choice perhaps if reading T G about 3d soundstage he likes more.

I'm not sure it helps you though...

hello,

Thank you for all this information. indeed I could increase the cabinet to 107 liters for the faital 12PR320 but in this case the troel filter should be modified because we go from 75 liters to 107 liters...or not...
In addition, I am trying to calculate the height, width and depth to put 2 rectangulars ports instead of the 2 round ports of 68 diameter and 140 mm in depth of the 3wc-12 (65-75 liters)... but it hard...

So you take tje low pass filter of the osmc tower. Problem fixed. It is around 400 hz. Read the thread.

Of course better chance of success following a kit. So the Andromeda Nova is maybe what you need...around 117L.. Find an ebeniste near the New Opera for the free cabinets or maybe the New HP System bd La Chapelle. A worked filter with the good caps is really a plus if you have a good dac or very good LP. Imho.

tip : if you make a 117 L cabinet and try lower litres loads just do a removable back : full with std bricks to reach the volume needed for you tries. Use adjustable vent too..

No risk to layout the front baffle distance to the wall with one meter minimum. More if you can with the side walls but consider distance between loudspeakers to be 2 meters at least (so 5 meters width listening room in that scenario, do the math if less width in your room).

Whatever try to have a non symetric distance of the loudspeakers with their side wall in relation to each other to avoid to increase (couple them) non wanted room modes - as listening room has a lot of difraction, makes your listening test with several singer reccordings to try to find a good enough center for the voice by playing with the loudspeakers position.... unluckilly it asks sometimes to play also with the non symetrical depth with the front wall with left and rigth loudpseaper to have the rigth soundstage with the reccordings : i.e. where voice is rigth in between the loudspeakers - if the reccording was made for the centred voice purpose-. It is because room has a lot of difraction due to non symetrical furnitures layout inside and/or non symetrical walls (windows, fabric on wall, furnitures, apertures, etc)

Try and error is your best friend : no standard listening rooms ! To be inside the triangle for the sweet spot is better (so the seat closer to the speakers than the distance between the coffins helps most of the time)

Edit : notice Gravsen design has to be heard with the loudspeaker at the rigth heigth. Whatever the stand, I would couple it with the floor not with spikes but with washing machine isolation pads that are easy to find and cheap - no problemo though with the spikes between the up if the stand and the cabinet.

thanks @diyiggy I have a pair of KEF 104/2 that have finally rocked their last jam session. I am trying to figure out what to do, DIY or prchase new. DIY is more value so I have been looking at Troel's options and trying to make the decision. These speakers are for a room that is 5m x 5m x 3m. The walls are plaster covered stone, wood wainscoting from 1.5m, wood floors, carpets, people, dog - its lived in. Pretty sure these speakers can fill the space.

Anyway, due to the size room, anything from 6" bass driver will work. The 104/2 works fine in all room size.
Here @wolfteeth made a thin 2.5 ways thin column with peereless and Seas drivers that are good. Also consider Heissman with its wall speakers.
Troels 10wc is certainly good but I do not like the 91300 tweeter from ScanSpeak in relation to the whole price. Just me.

I can help if you want to refurbish the Kef but if a mid driver is broken. Falcon Acoustic has parts too.
