Out of curiosity I did some pricing. Prices do not include taxes and shipping.
Erse: $47.07
Clarity PX (getting the right values required some paralleling of caps to get the right values): $97.10
Sonicaps: $496.26Speakers: TL Monitor 10s, RTA 11TLs, Fortes, Thiel CS 1.2

I've spent a ton of money on 3 different SDA's for caps and resistors. SDA 1signature, SDA 2a and SDA SRS 2.3tl.
I'm not in the least bit disappointed that I spent the money I did. Every time it was much more than I really wanted or could afford. Each time they went on a CC. Not once did I think "ya know I should have saved money and got the lesser product". I know had I got the cheaper version or cut corners I would have had in the back of my mind "what if" do not get the what if's. Most everyone here has been in your shoes.
Sonicaps are great because they have the EXACT values needed and they sound good, very good if you're asking.
Clarity has alway been just close enough yet not exact. They make very good caps, step up to the CSA/SA caps shouldn't be but a few dollars more. Put them in the critical areas and use the PX in the non-critical areas.
The Erse are not worth the difference for that little amount of money saved.
Lets be realistic here. You want to be able to smile and enjoy the heck out of these when completed, and you certainly will with good caps and resistors.
I've always in the back of my mind wondered what a full compliment of Clarity CMR's would have brought to the enjoyment over my Sonicaps.
One day I'll find out.

Looking at the schematic what is considered critical areas?

I can say with some confidence that the cmr cap bypassed with a duelund jdm or cast is about as good as it gets unless you go full duelund cast.
The price difference between those two are pretty substantial.
The cmr for the price is one of the best on the market. The amount of transparency, detail, staging they are capable of is addicting.
Path resistors are also pretty incredible- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
I actually have two sets of crossovers for my 1.2TL’s, one with Sonicaps, and Duelund’s, and another set with Clarity MR’s, and Duelund’s.. All of the inductors have been upgraded as well on both sets.
My advice echoes Ivan’s, just bite the bullet, and get quality parts, IMO go with Sonicaps, and Mills, and call it a day, if you get the bug later down the line you can look at upgrading the inductors.. -
Here is how my list would go if in your shoes, (without knowing your budget or financial situation) so I will keep it real.
Tweeters RDO-198’s (what is in there has to go)
Replacement Driver, this just might be the toughest part for you, but you will..
Spikes, yes I said it, a very budget friendly upgrade..
Dynamat the baskets on the drivers, and passives, another budget friendly upgrade..
Black Hole 5 to place on the back wall directly behind the drivers, only suggesting this while you have the cabinets open, but can wait till a later date..
Sonicaps and Mills for the Crossovers.
Sit back and enjoy..
On a later date when, and if you get the bug, you can order upgraded inductors, especially the 16mh, and order Duelund resistors.
Or better yet build a dreadnought, with an 800VA, or if you can find someone willing to sell you a 1000va as these are not sold right off the shelf..
Just food for thought..
Enjoy your upgrades nonetheless…

Just ordered 8 tweeters. I can now put what 198s I had back in my modded monitor 10s, RTA 11TLs and soon to be modded SDA 2Bs.Here is how my list would go if in your shoes, (without knowing your budget or financial situation) so I will keep it real.

Sonicaps and Mills for the Crossovers.
Will the sonic barrier from parts express work and if so which version the AB-4 or the MX-4?
Would the black hole 5 be cut in strips behind the drivers like the polyfill or is squares behind the drivers?Speakers: TL Monitor 10s, RTA 11TLs, Fortes, Thiel CS 1.2

Sonic barrier 3/4 in its a good product but not as good as the other two- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

How does the bh5 or no rez get attached to the back of the drivers? Individual squares behind the driver or a single strip moving from top to bottom behind the drivers?Speakers: TL Monitor 10s, RTA 11TLs, Fortes, Thiel CS 1.2

No, it is Placed behind the drivers on the enclosure wall.. Left center, back center to left and right array, then center right- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

You would cut the BH5 into 4” wide strips 24” long, and place on the back wall behind the drivers, you will still put the polyfill back in place..

A single strip 3 to 4 inches wide attached to the back wall directly behind the mid-drivers only. The strip should be as long as the distance from the top to bottom mid-drivers.

In my 2.3tl's I also ran a 3" strip along the sides. Once again just the same length as the drivers. -
If you have to, wait and save until you can afford at least the Sonicaps/Mills combo. Sonicraft will occasionally have a sale that will cut the price enough to be able to afford some better quality Binding Posts
Enjoy the process

I saw that as well, I didn’t do it either, don’t think it’s worth opening up my speakers for.. 😆

I used this Sonic Barrier and have been pleased with the results.

Black hole or sonic barrier behind the tweeter is a waste. Since the tweeter is sealed there's not much if any backwave like the open structure of the mid-woofer.
-
I seem to remember Darqueknight saying somewhere that he put those pieces behind the tweeters just to get more volume of BH5 into the speaker and that it wasn't because he thought tweeters had a backwave. In my mind, with 2 arrays of MW drivers close to that area on each side, there could very well be standing waves behind the tweeters too and the BH5 could help with that.George / NJ

That is one clean looking speaker, I am used to seeing glue running down the corners..
