Indian equivalents of the following DIY items.

Speaker Workshop is quite a capable tool, and can be used to obtain T/S params of speakers quite easily. All you need is a good sound card (I used a SoundBlaster Live! 5.1, I believe the new ones are even better), a good amp with a "Flat", "bypass" or "tone defeat" mode, and a speaker jig. I dont remember where I found the schematics for mine, but it looked a lot like the one ajju posted a pic of. You can also measure impedance of coils for crossovers using this program. I didn't manage to get the crossover design part of the software working, though. I used a SPICE program (see http://www.linear.com/) to simulate my crossover design, along with Rod Elliott's speaker model.

Even if your amp's not perfectly flat. SW will do a calibration run, in which it will compensate for nonlinearities. This will affect the dynamic range available, though.

There are rumours that soundcards which do DSP-based interpolation wont work well with this software, I don't think this is true. What this means is that whatever sample rate you set the soundcard to, it actually operates at some fixed freq (usually 48 kHz) and resamples the input stream to match that freq with interpolating filters. I know that my SB Live! did this, but I could not notice anything particularly wrong with the impedance curves when plotted with different sample rates.

Search around, there are good tutorials on how to use SW with a jig to measure components and speakers.

i spoke to my friend and he asked me to give u guys the lowdown...
By this month or the next Plinius is going to setup shop in India.
My friend is the Managing director of the company who are the authorised distributors to India.
u can look it up here..
http://www.pliniusaudio.com/ava/ava.htm#ind

Now, Junia Alva(my friend), who is the MD of Intech wants to lend a helping hand to the DIY community by doing whatever he can...
the above proposals stand...
Plinius are setting up two showrooms, one each in Bombay and Bangalore....
he plans to have a room adjacent to the showroom in Bangalore where the DIYers can come and do their thing...
So, Guys let me know if u would like to carry this forward...
Cheers,
Sachi

Julius used to represent Dynaudio i think. why no DIy in Mumbai? not enough interest?

[sachi]

Well..he used to deal with Dynaudio....

he is open to the idea of keeping the DIY setup where it is most beneficial...if there are more number of active Mumbai Diyers than in Bangalore...then i guess it would make sense in keeping it there...
neway i'll forward this to him and ask him if he is willing to keep such a thing going at both the places...
Where do u think it would be most beneficial?
Also for the people in Mumbai...they have maximum returns if they decide to buy the components from partsexpress since Junia's shipping lot comes thru Mumbai...that is where his gowdown is..

infact he is a member of the forum..and does check in at times...i'll ask him to step in if u think it would be better....cause he can take desicions better instead of me relaying things back to him...
Cheers,
Sachi

it did in the 90s. not sure today. anyway speakerworkshop with soundblaster live 5.1 is very adequate.

Dear Navin,

I was following you past threads...gosh you seem to know everything about the saga of audio in India !

From CMM to La Kozy to even my Dynaudio days....I don't know if we have ever met face to face....but you know the roots !

Anyway like Sachi said, I have got out of the Audio business some ten years ago to start a engineering software company. By the Grace of God, it is doing pretty well. Intech has several officies abroad & I am based in the US

I guess my roots in Audio have being pulling me back to India and I keep remembering all the hassels I used to have when I was trying to get thngs going while in India.

I was thinking if the DIY community in India are interested, Intech would be in a position to fund an operation whereby members could have access to the very best equipment with no strings attached.

Also I could arrange for parts to be imported at cost price.

The only request is that, I wouldn't wish anyone to absuse the system.

Perhaps a group of individuals in India could come forward to form the guidlines on how this would operate.

All inputs would be greatly appreciated.

In the meantime if they are any questions, please feel free to ask.

Regards,

Junia.

My age is now public! AARGH! :-)

I sincerly hope you all the best in your new venture Plinus as well as this DIY showroom.

BTW I chose to stay away from the AV MAX show in Mumbai. Last time I went it was not plesant.

Hello everybody.

Been a long long time (may be a year). I really thought that I had forgotten my password.

Feels good to post a reply here.

I got a auto notification that there was activity on this thread and I come back and its grown to 25 pages!

It took 25 mins to download all of them (I perfer checking them out when I am offline).

Nothing has changed for me since my last post in diyaudio. Like before, I check out DIY speakers and start salivating at the prospects of building one and then it dawns on me................I AM IN INDIA and have not yet found a sure shot way of getting a SHIVA or for that matter a DPL12 without thinking about customs. It kinda sucks when I think about that.

No one cares,
But given the tone in which everybody enthusiastically participate in asking or replying, I feel at home and hence just want to tell you where I stand.

Got myself a new job, lower pay but the job rocks and right now I am loving every bit of it. Looking forward to get the DPL12 (not one but two!!). Hope thats in the near future n hope no one here is givin up on me

[navin]

why not import them the old fashioned way. I have had no trouble with that expect the duties make speakers so much more expensive.

There are also excellent drivers available from Morel, which is a bit closer.....
