FE166En+FT17H "Concerti clone" (lots of pics!!)

[Leonidas]

This was the second "group-build".
After Fostex changed the parameters of the FE166 , I had to do some changes in my design as wel.
The first group build ended with everybody using the fostex FT17H as a helper tweeter.
So for the second group we decided to integrate the tweeter in th front baffle.
First pics ; Marco did, together with my brother in law, a great veneer job!!
and a pic if the first series, with "putt on tweeter".

Some pics of the inside.

forgot the glue for the pics!!

Time to introduce the builders: from left to right
Carlo , Marco , Leon (with beard) and Frank.
They had never build anything before!!
Everybody is very pleased with the results and is starting to improve their electronics.

I take 3 full saturdays to complete the job.
First saturday we do our own flatpacks and the first part of the build for one set of speakers.
Everyone else takes his pack home and does the same at home.
They have about 3 weeks for holding up to the same point.

Second saturday we continue with the second set of speakers.
So I can check upon the job the second person has done.

If there are some points unclear , then we use e-mail and digital camera's to correct each other.

I always aim that on each saturday a difficult thing can be done at my place.

Some pics of the first day ; starting with the baffle openings!!

[Leonidas]

After the holes are finished (and checked!!) I start to cut them to size.
I use an "DeWalt" radial saw.

[Leonidas]

Also time to do some more cutting to size.
And start glueing!!

Watch carefully!!

Each time a corner is put to place by "hand" after 10 minutes you can use clamps!!

The secret is the "fast"(15 min.) glue.

[Leonidas]

I'm in a lot of the pics because Marco took them.
I do one speaker , so they can watch the proces and then they do the other speaker.

The use of clamps only takes 15 minutes!! for a corner.
The first corner is the most important ; check always several times for 90 degrees!!

Also recheck after clamps!!

So take your time , don't rush things!!

[Leonidas]

Now it's about time for the PDF-drawing.
When you study the drawing you can see a difficult angle under the front baffle!!
It is the only angle to be precize!!
all the others are 90 defrees.
I shall try to explain the next steps as good as I can!!
This in combination with more pics.

[Leonidas]

First draw some helping lines with a pencil.
Then start rasping until everything fits as good as possible.
Use "closers" !! =
Triangular shaped hardwood pieces with 2 funktions :

1 Close the (slight) gapes with a lot of glue
2 support for airflow in the narrow piece of the horn

Time for dinner, back in about 2 hours!!
Shall I continue??
If nobody is interested .......it's a lot of work al them uploading......??

Yes, somebody is interested! This is the right way to post a build thread!
