Anil, awesome work as usual. Are these the ones you were talking about when I called you?

Anil,

Good Show :clapping:. I really applaud you for the DIY (with a capital Y). I have embarked on a DIY speaker project and will have a lot to learn from you, not just the transducer technology but the cabinet making. Looking forward to your blog being updated with the how to of cutting holes, and other mundane DIY issues...

Cheers,

Gopi

Cheers.

Congrats Anil,

Good choice of doing the carpentry yourself. The fruits of manual labor can be very enjoyable. Thumbs up to your effort.

BTW do you have any frequency response plots for the mid bass drivers. I saw the TS params from your blog and they are impressive for a locally assembled driver. Can you share more info about these drivers like the cone type, xmax, voice coil former type, usage of copper inside the motor etc...

Regds...

regds suri

Yes, I too was wanting to ask the same question

 

[ukjeyaraj]

Gr8 work Anil. Excellent finish at every stage. I am sure final look is going to be awesome.

 

[iaudio]

Iirc, Anil was going to use Vifa tweeters on this build.

 

[anm]

great work dude. Work on some subs, maybe one that go low as 5 Hz and 130dB loudness

 

[iaudio]

ananth, Anils floorstanders themselves go pretty low!

 

[grubyhalo]

Looking good there! Please post the design details of the pair when you have time. Thanks!

 

[Anil kumar]

Thanks to all for the valuable comments.

Give us more details on drivers, crossover etc.

Xover details: Infinity reference 2000 xover & vintage Goodman xovers, both are tweaked for best performance by Sreekanth, he is of great help to me.

I am using the same driver on one of the cabinet which has the same TS parameters. This driver was developed by Sreekanth, he has more data on this.

Few more progress shots......

Materials for spike​

Super Anil Sir. Way to go!!

So, this is what you were busy with when I called you yesterday:thumbsup:. Now, let me return your compliment - "you are always up to something".

In the last pic "Materials for spike", what material is that rod? Next time we meet/speak remind me to give you directions to a shop near good shed road who sell scrap aluminium sheets, rod and sometimes even billet (actually in very good condition) at reasonable prices.

Anil,

I have just joined this forum. Most of us know the electronics and acoustics but cannot manage carpentry and cabinet making. You seem to do it like a professional. Good luck.

Hi Anil,

Can you provide more details on the drivers used for the bass part?
The reason why I ask is: while one is made by Sreekanth, the other lower mounted one looks different.

Regards,
Goldy

 

[CANDUU]

congrats great work ,keep it up............

 

[Anil kumar]

Can you provide more details on the drivers used for the bass part?

Hi Goldy,i am using peerless drivers on one pair & shielded imported pair on the other bought from Sreekanth. Xover is tweaked for these drivers.


Regards,
Anil
