Can you post the specs for the drivers? How much do these cost you excluding shipping and customs?

sachu can u post the closeup shots of each driver... I can tell u how they can sound..

best regards,
Sandeep

The specs of the drivers can be checked out here

All together they cost me 6.5k...this includes the shipping cost within the US and an additional 450 rupees for shipping them from Bombay to Bangalore...
No customs was paid....

Sachi, good luck to you and happy wood working and crossover design. Hoping to hear your new speaker pair soon.

Dear Sachi,

You are more then welcome Sachi ! Plllleeeeeeeeeeaaassssssse don't embarrass me.....I was just helping out in whatever little way I could.

As the forum can now see good quality drivers are available at a fraction of the cost then what is being currently sold in India.

How much did you get the midrange for Sachi...was it $ 3 ?? I seriously doubt at those prices, if anyone could get such quality !!

Regards,

Junia.

P.S. BTW I did pay a lump sum custom duty, which worked out to a negligible amount as to the speaker drivers.............

That's true...no way would one be able to acquire drivers of such quality at these unbelievable prices...The midrange motor is a dual stacked magnet and is awesome....it has been maed to Infinity's specifications by Vifa...

Oh!...howw come u did not mention this to me earlier..
i guess it was all the other stuff u brought along that attracted the customs officials..

Regarding the transformer...chill ...it was no problem at all ...their factory is just 2.5km from my place.

cheers,
Sachi

p.s: the transformer is of very good quality, only need to see if thye can deliver the rated current...pretty heavy too( at least 5 kgs)..

benks good for you..got your drivers now what next...hope you keep us informed about your advancements..!!Now you see the third time members have helped each other( oh yeah not meaning business here) in what the other wanted..first amp for you..courtesy big ears..then drivers..courtesy Junia...keep up the good work fellow philes..in the mean time I shall resort to my fav past time shooting in air and something to gulp down. Now tell me benks where do you intend to start with???

thats as weird as telling me show me pamela pics and I will tell you how good she will moan during foreplay..heheheh you gotta unstrip those lace strings to know that amigo...but atleast your drivers don't make fake noises and fake anything else..

Talk about shooting in the air!!!
I must say that was a pretty darn good try...

Dear Sachi,

No problems on the Custom Duties...I just wanted to make the clarifications...you know by now I am on the hit list of several forum members for my straight forwardness & exposing their dirty bag of tricks !!! Boy I am soooooooooo very scared of them

Thanks again for the transformer !

Regards,

Junia.

P.S. Sub-Boss you are a riot !!!

darn good try....!!! I haven't even fixed my target and many have already started consuming anti lax to control their stool movements outta fear...think of the day when catch those double crossers too..they will have it fixed it up when i plug in corks...

hey benks what are your next plans of action

Hi All,

Just a quick clarification.

I will go out of my way to help any/all direct users, as to ferrying stuff at cost price from which ever part of the world they are available.

However it would be difficult if not impossible, to help commercial members who want to sell those "cost price" items to make a huge profit....I guess that defeats the whole purpose of helping out in the first case.

Additionally I would request, like Sachi has demonstrated, there should be no hassles as to the payment of the goods at the time of delivery in India. I am doing this in good faith I would request a similar reciprocal for all whom I interact with.

Thanks,

Regards,

Junia.

well, next is to come up with the plans for the enclosure and get it made...
meanwhile have ordered the remaining components for the Active Xover thru RS India except for the RCA plugs...
Should have them in a week or so..
Let u know when it is finished...

Sub,

I am still laughing from your Pamela comment.. that is indeed a good one!

So it's good then i will drop in at your place when all's complete..so i'm in the assumption that would be better for you too...i think even your room must be almost nearing completion...

room is kinda done...
the civil work is done..so is the tubing for the wiring ..
the window and door frames have arrined...
Flooring, wiring then plastering are yet to come..

Dude!...i myself have no idea when the speaker will be complete..so u can come down to my place anytime u feel like...no probs at all....BTW, call me up today if u can...will be at home ..

hey dude will call post lunch...may be by 3 when there is hardly anything to do

Hey Benks,
Congrats Man....you got those stuffs
I know it would be a quite adventurous and exciting project.
Let us know about the progress.
BTW have you decided upon the cabinet material and dimensions ??

Sachi,

Not sure if you have seen this earlier but some of the parts are also available from http://www.corrson.com in India. Prices are a bit higher though plus additional taxes to be added

-Rajesh

ok subboss right... here its how...

there are lots of factors man.. i dont know how deep ur are in speaker building but the factors consider alot...just check this to find what they really mean...

we can easily tell how its possible...

by seeing the cone type, diameter, voice coil size, and even magnet structure we can easlily estimate how it sounds.

Practical example: can u imagine how will it be if you use a 4 inch midbass for vocals, and 7 inch midbass for vocals.. which sounds more warmth and why... if you really want to dig deep into this then just check this and just dont just comment

Many even once I use to think that its impossible to expect the sound just by looking at the drivers...

But the problem in sachus midbass is that it has a foam surround it clearly says that it cant be as smooth as the butyl surround...

I do have tons of material regarding this and I m not suppose to post on the forum and get you confused...such expectation need lost of expertise in acoustics, physics etc....

Dont just comment man...

And even if you observe the benks 10 inch daytons then see it doesnt have big magnets and resulting in low BL product so that this driver cant give big and deep bass...but at the same time...since the magnet size is small the manufacturer need to sound the drive with better spl... so what he does is he improves the inductance of the coil so that it starts to give better spl...but at the same time a big drawback is that the woofer will not be in control...but one of the drawback in terms of driver speed and transient responses this driver will gives less performance...

So this results in slower in response but at the same time the tweeter is much faster in its transients...finally there will be lots of problems.

Why im telling u all these is that that is where choosing the driver is the foremost important thing in speaker designing...

anyway subboss there is no need for experts like you to tell all these things...

Let me no to go deep into the designing of the speakers and its enclosure...

Hope you support me or just be quiet...this is what is expect from you....

Well well nobody here knows or anywhere can comment how it sounds until it lands up in a cabinet with all the crossover,damping... By looking at materials if one could tell how it sounds then why do all need big labs to test.I still don't see a point how your expertise in physics and acoustics would help you to choose drivers like a cook chooses tomatoes for soup..mind you even those don't taste the way sometimes the way it was intended to be. Even now you feel you could do that then you are a supernatural specimen ...and i really don't need to tell where you gonna put that tons of your material...

we are here to make the forum a better place..and that write up of yours mentioning me to support you or keep quiet is hilarious...I will not support you nor keep quiet, any bugs up now???Look man stop making fun of yourself, you've had your share of goofing, now learn buddy...we are all learning.

Dear subboss its just upto some extent not perfectly the labs that they need is for precision results not for overview...
Even the big bees like make some common mistakes regarding their enclosure designs...

For me the ideal design should be like this...

Very fast response
Relatively smaller size
Min diffraction of sound
Max backwave absorption
Time alignment of driver
Time allgnment of crossover
Point source
Extreme weight of enclosure
etc etc...

For all the above things I make the design according to those specs...

Man just leave it yaar.. i do can expect its performance. Where the material I got it from highly experience people.
No matter what you think about it. Its master piece...

True..the midrange is foam surround...but for 3$ u can't complain....and it still is a Vifa..
I agree that i will not get deep bass but if the bass is tight enough its okay for me...
What is most important is the response till 35Hz should be good...below that this particular driver may have issues ....
The Bl product is around 11.4 and is pretty decent...the tweeter will always have a faster response because of the smaller mass...since the suspension(i.e the surround and the motor and spider) is dependednt on all of these and cause the magnet is small it it ideal to put it in a sealed box to keep the woofer from bottoming out(since Xmax is only 4.5mm)...
but i have decided to put it in a vented enclosure with a simple sub sonic filter to keep this from happening...

Cheers,
Sachi

ok baba you are right...its ok now...

yes ben you can use the subsonic filter...its ok..but what is the subsonic slope is it 24db?

yes...a subsonic filter is ussually a minimum of 24db/octave..

see subboss I am also learning and we always learn till we die there is nothing special about that...

Ok subboss you comment on me when i come up with a design which will optimise all these things... just wait for the spakers get ready coz lots of simulations are going on regarding the designs... anyway...ok man as you wish do what ever you want.. I just so open and speak everything..

Sonic master :

Dear subboss its just upto some extent not perfectly the labs that they need is for precision results not for overview... Even the big bees like make some common mistakes regarding their enclosure designs...

Yes thats true and I even agree to your theory completely that materials will determine the sound as thats what makes every thimg unique.

Man just leave it yaar.. i do can expect its performance. Where the material I got it from highly experience people. No matter what you think about it. Its master piece...

There you see I didn't know that you sourced it from highly experienced people...getting stuff from them doesn't make your stuff great and for me your assumption is like getting yourself buried by an experienced undertaker doesn't take you to pearly gates..

ok baba you are right...its ok now...

Look thats a bad way of reacting..c'mon man share with us too what else do you look in drivers to determine their characteristics??? lets share our knowledge. BTW whens your ProAc clone demo is gonna be in bangalore???

Benks, do you intend to do any testing on the final setup. Are you getting yourself an audiophile mic or just using an SPL metre.

thats what I always called a challenge..you've stood up now, I'm sure there will be many more criticisms from people once you launch your speaker..but don't be a sissy to call it a Proac clone...if you've put in your efforts then give it a name too....

this time i want to make my own design and probably im designing one of the fastest speakers from India. But the wattag is just like about 15 RMS nominal and 40RMS max... I have other option but im prefering this...

Probably i expecting to audition this system at Prithvi and just keep that system there itself for sale. I dont know that prithvi will accept for this or not?

The second option is to make the spakers which can handle with 100 RMS nominal I have to see..which one to choose...

Why do you not arrange your own audition with the amp what complments your speaker.?..If it sounds good and faithful then 15 wrms shouldn't be an issue..what config are you going in for??

Dear Sandeep,

Are you going to manufacture your own speakers or get it manufactured from someone else ?

Regards,

Junia.

Dear sandeep,

why choose bangalore to test audition if you have done all simulations at hyderabad??

Sub boss, I thought Sandeep was from Anathpur and not Hyderabad. I guess Ananthpur is not a big market I guess. I could be wrong though:)

rajesh,

But i think Sonic is based in hydreabad..or maybe ananthpur...he will have to let us know where he has set up his secret base...the sonic labs..

Hey rajesh,
well i hope to test it with Junia's equipment(test equipment) once i have it mounted in an enclosure...
i think he has the necessary instruments..
Cheers,
Sachi

benks you are the luckiest bum...you there..hehehe..you owe me a beer dude.thats great..go ahead man. Hopefully you can build me some bass horns in future...

now would'nt that be something...
hell i want a pair for myself..
man...why did u have to tempt me by mentioning them...

Sachi, must admit you have great friends These things cost a ton.

Dear Rajesh ur right im from Anantapur not from Hyd but there is no much market up here but there are few.. but my intention is to sellup in Bangalore....

oh subboss i dont have any sonic labs up here but at this moment me and ben are designing speakers for him ... I am thinking about his further improvement in building the speakers.. i have suggested some of the crossover points and enclosure desing considerations crossovers etc... probably i am comming to Bangalore on 12 or 15th but i would like to meet Ben and even you subboss. Im not getting my speaker with this coz i m comming there in search of some project works.

Dear sandeep,

Where do you stay in anathpur??

what man? you wanna come to my home?
