Indian equivalents of the following DIY items.

[sachi]

Got the entire thing for 6k including the shipping for the drivers within the US to my friend.
compared to corrson...i would have been able to get only two P17J woofers for the price.
the thing is that my friend is bringing them over personally to India..infact i think his plane landed just an hour ago in Mumbai.
What i am(on behalf of my friend) suggesting is that the parts will be shipped from the retailer(be it PE or madisound) to the US shipping company that my friend deals with. then it is shipped from there to Mumbai from where the drivers can be dispersed to their final desitnations.
the shipping cost from the US to India would be roughly 3-5% of the price of the components(say for 10k of components uwould have to pay nother 500-700 rupees max) and also the shiping will cost from Mumbai to final destination will have to be accounted for.
The thing is that my friend is going to offer this for free of cost and at cost price.
he will also not demand cash upfront..only thing he wants are gnuine interested parties who will nat back out after the purchase.(he said so.. at least when i last spoke to him abt this)
the purchase will be completely transparent to the buyer.
Ur inputs in this regard will be highly valuable..
will this work out for the DIY guys in India?
Cheers,
Sachi

p.s:as per his wishes, i will reveal the identity of my friend only after i get my drivers. i will also give u details on the way he carried out the transcation for me. the method i am suggesting will be almost similar to that. Let me tell u that as of now, i have not met him and he has been an online acquaintance of mine for the past 4 months. he has bought them for me and i have not put one penny on the table even now.
i will pay him when he comes to Bangalore in 10 days time

Hello Arasuk,

You asked: "Whats the size of drivers you are looking at!!"

At this time I am challenging myself to make a satisfying good imaging speaker using single 4" full rangers, obviously no crossovers involved. My task is to find the right driver for the task.

It is possible because there are some fantastic single driver high end speakers on the market. It is all in the enclosure design..and a good driver tostart with.

As Ajju points out, the JBLs I am using now are a very good value and sound quite good....but as he rightly points out, the HF is a bit weak....but there is something to work with (Ajju, what type of electronics are you suggesting to help the JBLs? an in line circuit?). I am currently breaking in the drivers in my temporary "tuppersonics", which are closed baffle clear PVC tiffins with polyfill stuffing. They are surprisingly ok at low volumes and are a good conversation piece.

Thanks to everyone with info on suppliers. Here is another that I will look into: www.pinecreekindia.com. Appearently a Fostex distributer in Delhi. Not sure they have the full range drivers, though.

one more thing...
my friend is willing to help the DIYer's in Bangalore by making available a place where they can come and use the MLSSA software for measuring the driver parameters and also use the LEAP software for enclosure and Xover design...all for free.
How does this sound...
Also some inputs regarding acquisition of drivers and components from the US are most welcome....
Maybe we can setup a meeting of alll the Bangalore DIYer's when he drops into Bangalore if the idea appeals to u and we discuss how to go abt this.
Cheers,
Sachi

...you Bangalore guys have it organized!

I have not got full details but it seems that Pine Creek (in Delhi)can get Fostex drivers. I am not sure if it requires quantity, or what that quantity might be. I will find out.

Does anyone have experience with www.speakerworkshop.com?
They claim to have some free software for testing at home with a PC/soundcard.

Stuart

[ajju]

yes..
this one is goood...
the only thing is you need a fairly good soundcard and a descent jig to be setup to help you with all kinds of measurements...!
I had an earlier version of this, and apparently it dint have measurements by the mass loading technique...
u needed to go the volume based approach and it was pretty cumbersome...!!

ajju

[sachi]

Hey Ajju,
A PC will be setup and i or we(if i can setup a meeting)can discuss with him abt the requirements(sound card ,etc).
i'll find out which version of MLSSA and LEAP he has and let u know.
OH, he al;so has a pink generator and a frequency generator(presently using thenm to break in my drivers) and these too will be made available..but these need a fair bit of planning.
Sachi

[ajju]

Ohh..
Sachi, I was actually responding to speakerworkshop..!!

guess MLSSA comes with its own break-away capture card...not too sure though.. Yes we shall gather all the diyers in blr..
to be frank, I have been out of touch with most of them..and worst part lost all contacts and numbers...will start hunting around agian..!


ajju.

[ajju]

You would need one of these...!!
Wallin jig...
Dont remember where ecxactly the circuit is..!!
It can be easily constructed at home..
here is an example..!

Thanks Ajju,

I am pretty new to the testing/technical aspects to fine tuning, discovering parameters, etc.

Other than Speakerworkshop, can you recommend a good place for a non-engineer to start? Or is Speakerworkshop a good start?

Cheers for the advice.

Stuart

PS: Thanks for the jig link
