Title: Current and future DIY projects
Post by: jororaitchev on 16 Jan 2017, 11:10 am
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:

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:

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 ....

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

Quote
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 /.

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.

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.
Title: Re: Current and future DIY projects
Post by: Armaegis on 23 May 2017, 05:01 pm
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:

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
 

Title: Re: Current and future DIY projects

I'm not sure I understand. Volume typically affects low end behaviour, but treble response is usually more dimensional rather than volume dependent.

(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.
Title: Re: Current and future DIY projects
Post by: jororaitchev on 24 Jun 2017, 06:58 pm
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.

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 like the shape it's taking.  Was pretty much hoping it would end up like this.

I continue with the collection of the cabinet;

Now I can make the exact measurement of the volume. And that's 31.5l, just as much as I need!
Oh, l forget to show you what I did to get that volume!
I maked a filter compartment (for the MW and TW), the W section will be in the box;

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.

   The craftsman ship is eyepopping and many hours must have needed to finish this beautiful

This is one the best threads! Amazing craftsmanship! Every picture shows hours of hard work, creativity and sheer brillance to be able to complete those enclosures.  The way you make the curved shapes is amazing, the execution is perfect for something thats handmade.

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.
