My new design

[fung]

Hi everyone, it's been a long time lurking, this is my first time podter.

I pursued the design, development and manufacture of loudspeakers for quite a long time. Mainly I develop products for other brands including the Hi-end speaker and mass production project. I also have my own brand, but I'm not going to disclose the brand name rightnow, sorry. I can see there are lots of philharmonic and experienced loudspeaker designer here. some are also good handicraftman, but some still can not put their idea into reality perfectly. So I think maybe I can do something about that.

See my new product attached(piano paint). There are more models in this series coming in few weeks.

It sure looks good. Is that one of the models you'll be selling or just a personal experiment?

Would be willing to share some secrets about the finish? Did you do it yourself?

[Tenson]

Is this going to be a DIY kit?

More info!

Fung,
Nice one there, waiting for some inputs on the finish if you're kind enough to divulge.

Regards,
Francis

Those look the schitznas.

I take it that isn't DIY'ed in the strictest sense but its a design destined for manufacture?

Eitherway, congrats!

Yes it is an existing product rightnow. It's one of my models. In the beginning I just design it to test the market, but everyone loves it by the first sight, so I'm going to design a whole series.

The finish is 16 layers of piano paint and must be polished very carefully by wool each time. I past the design to my factory to built it, and I must watch the whole process, communicated with the craftsman, explained what exactly I want, ortherwise I can't built such a cabinet by my own hands. When the cabinets were finished, I start to do the assembling and measurements, end up after a very long time of audition and fine-tune, then here it is.

Well, if you are interested in it, I can provide the whole kits including ceramic units and super high frequency ribbon tweeters(mounted backward) , 4 piano painted cabinets(2 each channel)and base--you can chose different colors, 6 x-overs, 30 ft14# and 18# Teflon silver wires, wool damping materials, 38 pcs aluminum components, some swichs and 6 pairs WBT binding posts, etc. It's quite a challenge to assemble all these parts together, and the cost is high, but once you finish the work and connect it to your amp, all your friends will very impress.

Hi Francis, what exactly you like me to divulge? I'm readly to answer your questions.

Thankyou. You 're right, it isn't a DIY product strictly. This speaker is intended to design for manufacture. But still its quality was to be set as a hi-end speaker, from my view it is one of the best models in the world which adopted the ceramic units.

Fung,
You have described part of what I wanted to know and thanks for the same. So 16 coats, eh.... no wonder it looks good even as a photo.
The wool you mentioned - is it steel wool?
What is the cabinet made of - MDF or Plywood or...
What surface preparation was done prior to painting - filler, sealer, epoxy....

Regards,
Francis

Its most likely to be synthetic microfibre that was use flat out the finish, definitely not steel or wire wool since that is a harsh abrasive and would leave deep scratches in the finish even after coats.

Its a lot of work to get a high gloss finish but the results are very pleasing to the eye. I'm in the process of doing a piano black:

Shinobiwan,
Now, you're making me jealous.
My mains are waiting for a piano(close to/far way from) finish. At least that's what I decided to do.
Still want to get some more ideas before plunging into it. Right now it's bare-naked-MDF.
Couldn't find sanding sponge(most of u guys will admonish poor me) finer than grit-600, hope it will be sufficient.
Gonna use spray can paint so I'm sure it won't even come close to your finish.
Then, in typical DIY fashion, I'll be forced to say "it looks good to me"

Hi,

It does look really good! The kit might interest a friend of mine. We went to the Hi-Fi show recently and he heard the Marten Designs Coltrane speaker and really liked it. I was trying to convince him to build one but when I had to explain crossovers I think it was a bit too technical making measurements and so on.

What are the '38 pcs aluminium components' for?

Do you have an email address I can pass on to my friend?

Also, just out of interest, when you put the tweeters in the back... do you wire them in phase or out of phase with the front ones?
