Do not worry, you won’t be happy with your new speakers as well. It is a little dirty secret that no one told you yet: speakers do not give happiness. 

In my case only speakers can give me happiness, because with electronics I don't see any way to upgrade.I had (bought and then sold half price or even lower Smile) already almost every highend DAC (EmmLabs, dCS Scarlatti, Berkeley Alpha, MSB Platinum, Antelope Zodiac, Trinity DAC (this one not sold yet)) and some good amplifiers (Gryphon Colosseum, Tidal Impact (also not sold yet)) to finially choose the best for my taste. Now I just need best speakers Smile

To know exactly what you want it a very good thing. If you do build your own speaker then there is another important factor: to know how to get there. This one a bit tricky as there is no definitive ways and it would requires some experimentation with yourself.

Sure. Only results of my own experiments can guide me. I agree.

Regarding your last drawing. The way how you depicted the frame you will not have time-alimented. Look at my thread about Mocondo Frame

Thank you for the link. I'll study it.
 

….and do not discard Jessie’s ideas in his own thread.
 

Jessie Dazzle Project ?Great thread, thank you!
I personally feel that I tis a bit premature for you to think about the frame. I do agree that is very pleasurable to draw the sketches and visualize the future system but at this point you do not know what kind drivers you will be using, how you going to use them and what kind horns you will be employing. You do not even have a final decision how many channels you will be loading into the frame. So I would advise to finals the acoustic system entity and only then suspend and efforts to put them in attractive design. BTW, the ideas of fame you had above will not work from structural perspective. Those “hanging” horns are incredibly heavy and you clearly have insufficient structural support.

Thinking about frame is important to understand what is possible and what is not.For example, this drawings crearly shows that combining two 2m horns is almost impossible.And yes, it is very pleasurable Smile
When I say that it is a bit too early for you to think about the frame then do not take it little. You can do whatever you want BUT you are wasting your time as I absolutely assure you that you will change your mind about what you want and how you want AFTGER you actually start to listening the channels and decide what  stays and what is goes away for your installation. So you will 100000 times change your mind, so any todays “idea” will become irrelevant in future. Trust me, I was there.
I trust you because your experience is unique. I don't know if any other similar structured knowledge base exists in the world...I think not.So, I very much appreciate your comments. Thank you.
When I got my first 3 way horn speakers from one of the famous DIYer here, I stil was not happy with lowest bass and highest highs.So I built tapped horn and bought many different HF-drivers to get better highs.BMS, Faital, Fostex, Beyma, JBL 077 and even very expensive TAD-ET703 (same VOX Olympian has).They all was much worse than my very old Jensen!Only with JBL LE085 I got what I wanted, but still missing highest highs, so I've ordered RAAL Lazy Ribbon as this is the only driver with sensitivity around 110db at 14kHz!I've also ordered latest JBL D2430K, just because I like JBL LE085 and interesting to see how is the modern JBL in compare with vintage one.

My next step is to try different drivers for MF.I have GPA 288 (Altec clone) and I like the tone, but it can't go lower than 500Hz even in 2m horn!Small Atlas PD-5VH (Klipsch K-55 clone) with 1" throat gives 300Hz easily in this horn!So, I want to try some 4" diaphragm drivers with 1.5" throat which can go lower, like JBL 2447 or 2451-52-53.May be LM 555W (WE555 clone) is also good, but very expensive...more expensive than new Vitavox S2.New Vitavox S2 is also very nice driver...VOX Olympian mid-range sounds amazing for me during this year Munich Show.May be I'll end up with Vitavox S2 like you.BTW, the DAC I use after all I had is Lavry Gold Smile
