What sound system can produce pure sound for classical music performance outdoor?
I want the audience don't realize if there is a sound system at all.
I don't want any hum or any sound from the speaker other than the performance.
I want it clean and genuine.
I want to build it myself.

I'm not sure why you think you need to specify that, any decent quality or better system will be quiet and accurate.
Will this system be amplifying a live performance or a recording?
How big an area does the system have to cover?
Much depends on the answers to the above questions but it is likely this system will be bigger, more complicated and expensive than you anticipate.
This would be a difficult but interesting effort. We have the same problem in our area with outdoor concerts.
The natural sound is weak and thin, but if reinforced is distorted and ugly. It does help the balance to have
a solid rear wall close by, if possible.

Outdoor can be easier for sure but often requires a larger system as there is no enclosed environment to assist.
I agree with conanski on all points.

The first line of his query tells me this is live.
It would be nice to see pictures of the area in question. Is it an open field or surrounded by trees or in an amphitheatre or...?

Lewd, still far from obscene, even to just profane.
The size of the hall is Tennis court.
If this is for a single event you should look to rent a system. I would use six of these speakers spread around. If you put a bunch of this type of speaker around it will give the special impression of instruments playing from an orchestra. Think of each speaker as a musician. You may be able to rent them. https://www.amazon.com/Bose-Pro16-Integrated-Bluetooth-Built/dp/B08JZK4KVZ Here is another option that you could buy or copy if you wanted to build something yourself. https://www.parts-express.com/Gemini-WPX-2000-Modular-Line-Array-Speaker-System-235-184 I think a line array would work well as they have a wide horizontal dispersion, like a string instrument and narrow vertical dispersion which will help focus the sound where you need it as your audience will be on the same level as the speakers. The sound from a line array carries farther than that of typical point source speakers. The volume level you need will determine how many speakers you will want to use. If you need very high levels you will need to look at more focused systems like those used at outdoor concerts.

In the renaissance they used instruments such as shawms (schalmeien in Dutch) for outdoor concerts. They were so damn loud they didn't need amplification.
For playing outdoors ,,, there is the marching band. Not so easy to reproduce with speakers.

I suppose so. It's an array of small speakers with a woofer in a box at the bottom. You might try to find a store to listen to something like it before spending money and time to build it. I think that many large music instrument stores that sell sound reenforcement gear would be able to demonstrate the Bose or similar speaker. It would be difficult to build one for less than the $300 that Parts Express is selling that speaker for.
Just a passing note that both commercial and my DIY versions of those column speakers sound pretty awful: the HF balance changes drastically with distance, not to mention the narrow horizontal dispersion up there.
Some of them tend towards a point source by using dedicated tweeters and rolling off the lower midrange drivers. Those have a better chance of sounding good. Even so, they lack the lower-midrange "grunt" of a typical 2-way PA speaker.
IMO, for this to be remotely convincing, here's what you'll need to do:
A string quartet wouldn't be terribly difficult. A large orchestra is the sort of thing I'd only approach with a considerable R&D budget.

IMO, for this to be remotely convincing, here's what you'll need to do:
- Start with a good multi-track recording of whatever you're trying to recreate. By multi-track, I mean one instrument = one WAV file. If there's 72x instruments, you'll need a good playback system and it'd probably be worth investigating Dante as a way to transport the audio.
- Next, design a set of speakers that will do a reasonable job of mimicking the radiation pattern of the instruments you want to replace. Here's a good place to start listening: http://soundmedia.jp/nuaudk/ - Keep an RTA running, and make notes about the radiation pattern of the different instruments.
- Once you've designed/built/tested those speakers, figured out the amplification and audio distribution, arrange the speakers how they ought to be placed.
- Check each one is working individually
- Press Play on all channels, and enjoy the fruits of your labour.

Orchestra piano pipe organ can be handled very well with a 15" woofer + 1.4" Compression Driver on horn. Altec Lansing Voice of the Theater, Electrovoice U15, JBL 4367, Peavey SP2(2004). If you do not need 15000-20000 hz, and most of the audience cannot hear that.

That is very difficult.
You would have to hide speakers in the orchestra and you would need many of them, being of very high quality.
And you need a very good technician to set the system up.
It's not easy to trick the auditory sense for people who are not prepared to do so.
It's not possible to make it invisible. And forget about the
To build it isn't the problem. The problem starts with picking up the instruments, positioning the mics and mic-stands (no, just 2 OH mics won't do it), continues and ends with mixing it (all that has to be a done by a sound tech with experience with classical instruments). It's clear you can't do that yourself and I don't know when the concert will be but I can promise you, the time is way too short to build and develop the speakers, learn how to mic and setup and mix it. It will be hard to get all that done end of 2025 unless you can spend ~3-4 days per week on learning how to do it. If you don't have anyone to teach you and decide to be an autodidact, double the time needed.
A tennis court. Uh-hu. Will there be a stage? Will the audience be on the court? A court with tribune? Tribune all around the court? Distance from the stage to the tribune?
What's your budget? If it's a quartett and there will be 150 ppl in the audience and you have none of the equipment, calculate with ~8-10k €. If it's 8+ musicians, make it 12-15k. If it's over 300, don't start doing it yourself at all.
