Two-Way Designs Incorporating FR?

HIFI is like sex, as long as you don't hurt anyone, the stuff that pleases you is fine for you (and your partner, mostly called WAF in both).
Also, there is a very wide range of options for basically the same thing. So what you pick, after trying out, is your choice.

I'm no great fan of FR, even as a nice little pair is playing in my electronics work shop. I understand that many people like them. On the other hand, most are very cheap to DIYS. A decend FR starts around 30$, a good 2-way kit will be more like 120$. Decend means the region that gives an objective good result, better than commercial consumer class. They give people, that can't afford more expensive stuff and often never heard really good speakers, the opportunity to voice their opinion on the net. Which may not lead to an objective discussion, but give cause to some poor guy/ rich guy confrontation. Ending any audio objectivity.
Some regions of audio have been democratized, the CD killed the expensive record player, cheap D-amps win any blind test. A anyway, this has not happened with the speaker system. Physics is a dictator, no democratic majority thing.

A feeling not helped by videos like this one:

That video is mostly a spinning progress swirly. He got as far as saying “most FR systems are crap”.

He is largely right — there arer a lot of crappy FRs, but the best FR are really quite good. I have never heard the Cube (did a couple designs), it is well respected, price went thru the roof when they went to distribution. Snide has similar rep they are more affordable, but these drivers represent price tiers high above what most people are willing to afford. For me MAOP is in the range of max cost, they are very good, and don’t have whizzers. Whizzers turn a FR into a Multi-way with mechanical XOs. I find the double whizzer on the big Cube a bit scary and IMO quite ugly (that lkast shouldn’t affect tehy sonics).

I am wondering whether a good 2 or 3 way kit using Scanspeak/SB drivers with crossover (or at least plan) included might be the best way to go in my situation. Ones that I have come across include Troels Gravesen's 18W Mk2 and Illuminator 71 or Jeff Bagby's Spirit Wind, Helios, Sopranos or Kairos. If you can recommend any one of these or know of any others please let me know.

One other more radical solution is to try to reproduce a simpler version of something like this (pic below):

Made of concrete but the oval design appeals to me greatly. And they claim to go down to 25hz. Could be made using the thin ply glue laminate method used in my triangles but would need help choosing drivers.

But I'm also keen to see Scott/Dave's 2-way FR design.

I haven't watched the video as I have a bit of a dislike of them in general (brief rant time: how often have you been searching for a piece of information, found a source, and then groaned because it's buried in an hour+ long video with no idea where, forcing you to either give up or sit though goodness knows how much tedious waffle before you finally find the fifteen seconds of relevance to you? I find the written word a mite easier to navigate. Perhaps it's because I'm a brontosaurus).

However, as Dave says, there are good wideband based systems, and bad ones. Many were / are bad, but as noted there are good ones, the main difficulty for people new[ish] to the field figuring out which is which.

I've forwarded the details to Dave, who is probably still recovering from the palpitations 😉 but they're there. While he's recovering from the horrors :vampire: I took the opportunity of simplifying the filter somewhat as I was able to hit the target LF transfer functions without the Zobel I originally used. This one is a medium / modest sized floorstander however rather than a standmount. One of the latter is in the queue though.

If you go for a Troels Gravesen's, you will probaply get another version of the Dynoudio sound. I may add can not audition them before purchase, so it is only a guess from the drivers, complicated crossovers and frequency responses he publishes.
If that is was what you search for, you could simply change yours for a smaller version from Dynaudio...

Seconded

Got it, haven’t looked at it. Busy dealing with the Landlord and sketching ideas for turning downstairs into a suite. No stairs is looking more & more interesting as i have graduated to 2 canes to “walk”

(means there will be a gorgeous sounding apt in one of the most wonderful places ine world will be up for rent when i move downstairs)

Good point about the Dynaudio sound, I hadn't thought about that. As I get older I have definitely moved towards the brighter and more forward sound of B&W speakers and I guess that's what I'm looking to build now. The MA drivers certainly have that appeal in the mid and upper ranges, just looking for a bit more "cone real estate" in the lower registers...
 
I don't generally design for that type of response unless it's a custom commission; I normally aim for a more neutral balance, so probably not as is / will be. The Scan mid-tweet in question here doesn't really have significant HF peaking beyond a milder rising trend which averages out to a fairly linear presentation once the power response is factored in, so realistically something different would be required.

Best value for money for more open sound are Monitor Audio Gold speakers, at least for me. Good price for SH for some MA Gr10 or Gs10, even Gold100 and they will beat B&W in price range IMO. For diy MA are mine choice also, there was some Scotts designs with smaller Alpairs and CHN110 if I remember correctly

Thanks Cindra. Yes I like Monitor Audio speakers, but to my ears B&Ws are slightly ahead.
