My DIY Enclosures - Common Thread for all my Enclosures

[Vineethkumar01]

Lovely build of those gorgeous looking wave guides. Dont mean to hijack the thread...but can you please elaborate a bit on these horns. The frequency range, efficiency and compression driver used etc. Not everyday that we get to see horns around here

Thanks..
These are the EXAR 400 horns from Marcel Batik (mabat on diyaudio). It accommodates 1inch compression drivers

ATH - Advanced-Transition Horns

The frequency range can probably be anywhere from 800Hz to 20kHz depending upon the system configuration.
Here are my polar measurements of a 1-inch BMS 4550 on this horn (raw responses)
My plan is to also try out this horn with the SB Audience Rosso 65 1.4inch CD with a custom 1inch adaptor designed by mabat.
Measurements taken 1m away from horn mouth (gated at 4.1ms)

On axis frequency response and impedance measurement together

VituixCAD plots
Normalized directivity computed with reference axis as 10 degrees off axis

Here is what a rough active filtering on this horn can do



And here is a rough first-cut passive filter

Thanks for sharing...the measurements look sweet. And a wide range of 800 to 20k is excellent to have without any crossovers in between. All the best to trying out the CD with the throat adapter.

Very good polar charts Vineeth. There are no crossing lines in polars meaning a very good performance

Due to health issues (lower Back Pain) i am a bit slower on my builds, I have a total of 4 Projects which were yet to be completed, I really appreciate the patience of my clients who had given me the opportunity to make their enclosures, They have given me lot of time to complete their enclosures. I didn't touched a single tool or a piece of wood for about a month. And i have decided to take a break after completing all the 4 Projects. 1 of them is completed which are small Bookshelf enclosures and there are 3 more pending. Here are some Photos of same.


Earlier it was decided to color the enclosure completely, but the grains of Birch wood turned out so nice that client insisted for a dark stained Rosewood polish, and top coat is clear Matt PU paint.

Stay healthy and keep on building !!!!

Take care and get well soon and come back all hale and hearty. wishing you the very best !

Another Project Completed Slowly and Steadily.

 

[yogibear]

Love them ! Beautiful Sadik !

 

[ponomariev]

They look beautiful indeed!

What do you use as grill fabric?

Do show us the drivers..

These look like an MTM configuration?

Love them ! Beautiful Sadik !

Thankyou Sameer Bhai.

Thankyou. Its Grill Cloth you can get it from The Audiocrafts

Do show us the drivers..

Its Full Range Driver. The Driver is Mark Audio MAOP11.2. & Enclosure is MLTL

Dear Sadik, I hope that you feel better now. Don't worry, you will do many outstanding masterpices by your artistry. God Bless You. Regards.

Once again, very good job done!

Hi Friends, Now a days I am not very active on hifivision, In fact I am not getting enough time to document my built journey so I thought of at least make a thread where I can share the photos of the complete enclosures. So from now on I will be posting photos of all my enclosure projects in this thread.

So the First post in this thread are custom designed enclosures, they are huge with external dimensions as 1280 (H) x 380 (W) x 420 (D)

These enclosures are RAW finish. (No Veneer, No Putty work, no Primer no Sealer no clear just RAW enclosures and Shellac Polish). One of my hardest project till date because I had to take great precautions during cutting and assembling them. The DIY guys may be very well aware of cutting plywood in the opposite grains, The Plywood gets chip off while cutting along opposite grains of wood. A slight chip off will ruin the complete look of enclosures.

Lets enjoy some final built photos of enclosures

While taking up this project i had discussed with user and made it clear about all the difficulties which may occur in the enclosures, (like chipping of plywood while cutting in opposite grains of wood, some air pockets in the internal of plywood after cutting, or may it be some dents on surface of plywood etc) he also understood the same and gave me green signal to go ahead and make the project happen. Secondly making grill is not my cup of tea but still i manage to make a good looking grill and for such a huge enclosure the grill was also another task.

But in the End this Project turn out to be a Master Piece. Next Project is soon on the way... Stay tuned.

Superb ...Very nice

Get well soon Sadik bhai!
And needless to say great builds!
