Hello,
the first project of my DIY loudspeakers i have served Ti6k- JBL. My first contact with
them, was in distant 2005.
I started working with them in 2009 and finished in 2012.
The loudspeakers are "SEAS"- Excel / Tw-1”, Mw-5”for center 2х 5.5”,Bass-8,5”/ and cross-over parts- "Intertechnik".
Have are some pictures, if there is interest, i will continue.
Regards!

THERE IS INTEREST! :lol:
I see DIY projects like these; have great fantasies about making something as beautiful as your speakers, but I always crash back to Earth once I remember my carpentry skills. :roll:
Reading about others' exploits gives me a nice warm fuzzy feeling though! :thumb:

THERE IS INTEREST!
Really big interest. It is seen everyday.

Beautiful work!
I assume you used burl veneer and I'm intrigued how you got it so well blended in the corner radii. If they sound as good as they look, it's a beautiful thing :thumb:

Beautiful beyond words!

Jazzman53Beautiful work!

No, not burl It is "Birds maple",

Now go, how they made the speakers:
First did this "home-matrix"....
On fire therein 8 layers / 4mm / MDF.
The result is two such shells ...

Follows; assembly of the structure veneering veneer 'Birds' maple' toning and everything else ....

Hi,
Fantastic carpentry skills and great looking speakers. Who designed the crossover for you?
Cheers Rod
-
Very Nice Indeed!
Toning? dye? what
type and subsequent
Finishing?
yes, the crossovers
would be of interest.
-
Beautiful work. Tell us more about how you got that finish!
-
Rocket: ....Who designed the crossover for you?
Аll my design. Everything is done by my hands.This Is the technical parameters:
Nominal impedance- 8 Ohm
Freguency Range 30Hz-20kHz
Characterstic Sensitivity(2,83V/1m)- 87db
Long Term-110W
S Clark: Tell us more about how you got that finish!
Thanks for the good evaluation!
Auto acrylic varnish, high scratch resistance and UV protection. The last thing is done is polishing with polishing paste 3M- numbers from 1 to 3.
I have used Italian, Spanish varnishes, but I'm most pleased with the Polish. American products can hardly speak / for obvious reasons /.
Regards!

Stunning craftsmanship with an elegant design, very beautiful. Do you have surround speakers built as well?

Wow, can you say inert cabinet. That is one solid piece. What do you anticipate the total weight to be when finished?
-
I apologize be, dont know. Such projects do not do every day.
-
Really really impressive.
And I bet they look even better in person, pictures usually don't really capture how good a nice finish looks.
Wondering how you did the veneering?
I would guess vacuum because of the curves.

Funny, I was thinking if you had a technical person (I of course had no idea that would be electrical engineer) combined with a master woodworker, that person could make these cabinets. Hey, I was in the ballpark. Just awesome work there jororaitchv, you should be very proud of your work.

Highly impress by your work, MAD SKILLS :o :o

Just from eyeballing it, I feel like the volume is around 95% still.

It's a joke, there are such people in Bulgaria - , wizards, magician which foresee the future by throwing beans.
In America the shamans are guessing the future by throwing bones.
The reason for this joke is your statement:
- ....."I feel like the volume is around 95% still."
-
Oh I see. My reasoning/estimation was the bracing was looked like it was taking up about one eighth volume (pure guess based on stacking heights), but then with all the holes cutting out maybe 60% of the bracing... it worked out to 5% :green:

Project "J&N-2",
(http://www.audiocircle.com/image.php?id=162714)
(http://www.audiocircle.com/image.php?id=162715)
Why and how should a beautiful project be changed at the outset?
The problem is in the frequency of around 5000Hz; There is a peak ,which strongly influences the average frequencies.There are two ways to solve this problem:
- Adding one more MW,
-More complicated construction of the filter I don't know the exact name , maybe (reager).
This project may be look beautiful, but will be changed.
As I wrote at the beginning of my post, everything is done by me, I do not use ready filters / and I do not recommend it to anyone unless it is a ready-made kit with cabinets /.Will try to explain why this project is changed at the very beginning.
-
Do you know the cause of the 5000Hz peak? Is it a cabinet resonance? If I were to make a guess, it would be based on the alignment and sizes of the holes cut. 5kHz is roughly 68mm.

A very interesting assumption, but we can be a more serious.
Characteristics of the speaker in 55 liters closed volume:

Characteristics of speakers with and without filters:
(http://www.audiocircle.com/image.php?id=162718)
Transmission characteristics of speakers:
(http://www.audiocircle.com/image.php?id=162719)
(http://www.audiocircle.com/image.php?id=162720)
What should I choose in this situation?
-1 option, add one more 18 FX001,
-2 option,remove one 26 FX001,
I chose a new progect with 4 identical speakers:1 х 26 FX001, 1х 22 FX001, 1х 18 FX001 , T 25 CF002
-
I'm not sure I understand. Volume typically affects low end behaviour, but treble response is usually more dimensional rather than volume dependent.

Continue:
(http://www.audiocircle.com/image.php?id=164014),
(http://www.audiocircle.com/image.php?id=164015)
I fill the cabinet with water to the red line / there ends the front panel with the speakers /.
(http://www.audiocircle.com/image.php?id=164016).
I find the volume - 43l, I deduct the weight of the internal ribbed - massa 3.4kg.
And the net volume of the cabinet is 39. 6l. More than I need, I need about 35l.
There is one more option, but for him later.
-
The problem is that my investor likes the vision of the column.The decrease in volume must occur inside the construction of the cabinet.This sends the project in a more initial phase,we have a new requirement for the project, second W18 EX001.

I can now start collecting the cabinet;

-
Looks great, but why do you apply finish to the internal bracing? I assume no one will see it once the speaker is finished.

After installation of the cabinet (without the front panel) I will do the second measurement of the volume after all additional work - with water!
It is normal to pay proper attention to impregnation.

I have an idea to make a new project to in the base there should be two 10" loudspeakers - just an idea. They look like animals, maybe dinosaurs/was mentioned in this post/, but important are 20Hz.

A very underestimated moment - work with multilayer MDF!
There's still a lot of work on the stands.
I show you a few pictures of the front speaker bases, the rear speaker stands will look like the same;Always been a problem with the MDF, especially when we have a multilayer construction. Over time, individual parts are beginning to show up - all of this is the result of improper processing. Soon I will show you how to deal with this problem.

I agree, remarkable work, hardly can be called diy such is the quality of the workmanship. I believe the builder has stated no CNC machines were used, all hand cuts.
