Speaker Designers Needed.

[chander]

A friend is visiting in Jan. He loves wood working and audio. A woodworking studio is available for hire/use as the owner is leaving on a holiday.

We want to make our own speakers - can anyone help us with the following -

- A speaker design for
- 3 way speaker
- With a concentric driver - 6.5/8 inch doing the mid + treble duties.
- 12 inch woofer
- Aim is to get 40Hz in room. Do not care about going lower at all.

Are there any such designs that exist.
We will be turning these into active speakers using the nCore Fusion Amps - to be driven using A streamer only.

PLEASE NOTE - we have no idea how to make speakers - we meet once every couple years and take up a super complicated project and just have fun doing it.
We do not even know if any such thing exists or should even be attempted.
But the idea does sound incredible.

Any particular design you can give a link to? Like I said No idea where to begin - a plan laid out will be helpful

quality coaxial mid and tweeter driver are rare. It usually come with some compromise in linear response and dispersion. A separate mid and tweeter will be budget friendly. Also all depends on budget. DIY is usually has no resale value. I have made losses in selling diy amplifiers and modules. But my goals were to be active in diy and listen to sound for some time. And selling my diy helped me fund my new projects. So you will have to decide if you want quality hifi speaker once and for all or just enjoy building speakers. Also some diy speakers may need powerful amplifier to exploit its full potential.

Budget is reasonable & flexible - It is more of a passion project so all will be written off as R&D. But we do not even know where to start looking at yet. How to choose drivers etc.

Not planning to sell these, they will be used to host.

NOTHING.

ok
audiofy and diyaudiocart has some drivers ans kits. Probably you already have seen them. a good 3 way will require at least 10 inch woofer according to experts.

Vmt.in had some nice coax https://vmt.in/products/cx8f140-x8?variant=49544762949922, unfortunately currently out of stock, you can check with them for restocks. B&C also has some good coaxials.
Another good option is to clone these, (if you have space that is)

Since you are using DSP amplifiers, you can always build custom crossovers fitting the drivers easily, no more iterative passive crossovers.
This one is easy to build too, less things to go wrong, with DSP one can always change things. You will have to measure and build crossovers in DSP.
