About the 'HUnter's speakers

WoW!! To an audio DIY novice like myself , I find the tech talkmarketing to be very impressive. I agree with most of you here that Hunter should stick to a few popular driver models but am also led to believe that he wishes to convey a flexibility that may not be exhibited vividly in other manufacturers as in custom made to order designs which is an excellent idea.

Given the over the edge details that he has provided, I wonder if he has a website to which we can look to from time to time for more information.

Hunting Hunter Audio

corbato said:
The elusive guru strikes again !!

Angshu....would you care to narrate your exp:devilr:


Both Ashok (Corbato) and I made futile attempts to track down Hunter Audio recently. I was passing through Cal and had requester Hunter if I could come over and have a look at their much 'self acclaimed' drivers.

We exchanged couple of SMS while I was on my way to Cal. But finally when I did arrive and called them, this is what I understood from them.

I was having a bumpy ride and was on my way to 77B Amherst street the corporate headquarters of Hunter audio. I had a bad crackling distorted cell connection and could not hear anything very clearly and to make things worse the taxi driver kept blowing the horn. In Cal taxis do not run on petrol, but on the propulsion of the blowing of the horn. So Hinter Audio please excuse me if I have not understood you correctly. No offence meant...

1. Hunter Audio did not have any sample driver to show me in their office. They said that they can show me a sub fitted in their car driven by 3 batteries in its trunk. I was more interested to see the raw driver instead of a sub with 3 batteries. Unfortunately the car was having it's AC serviced and out of range on my speeding horn blowing taxi. So I lost the opportunity of my to see a sub with 3 batteries.

2. Hunter Audio was reorganising and was not in a position to supply to DIYers out of Cal as there was no one to pack the drivers.

3. They are waiting for a bank loan which will enable them to have a website by a year's time, they promised there will be over 200 models to choose from. Till then I think we DIYer in India have to live with the Vifas, Peerlesses, Focals, Audaxes etc. if we can import/smuggle them in.

4. I asked whether I can see some standard drivers in Madan Street, the electronic heart land of Cal. They said I could see only the cheaper types, as the shopkeeper only kept models costing not more than 200 bucks. That was OK by me but before I could ask which shop I could see the drivers, we got disconnected.

While I was hunting for the Hunter audio drivers, my cab driver in the mean time must have run over numerous dogs and almost reduced the population of Cal while trying to negotiate the human/animal mass on the road or what ever left of it after tram lines, parking trucks, hawkers and stranded buses. I was getting late for my flight, and my cab driver was determined to give the most thrilling roller coaster ride of my life.

At the end of the day all I was left with was a numb bum. I was disappointed that I could not see the Hunter Audio drivers, but at least happy that I was alive for my next hunting expedition.

Till then happy hunting.

Saha Capacitors

My take on getting stuff:


George:
Saha sounds bong. Let's coax Angshu into the job 🙂


In fact I tried contacting Saha capacitor a year back, but did not get any response from them, very typical of Indian manufacturers. I was told that they are no longer in business, I am not sure whether it is true. Can the Bangalore friends please find this out.

Navin ive replied to you in my thread - transducers manufactured by me in india

thats in the trade section for others to have a look - bye

this thread gets more interesting and enigmatic by the day. like others I would be keen to see/experiment with a basic build for a 5 or 6 inch driver. also, I saw reference to PA/instrument applications, and the same holds. I woul dbe keen to see a basic 10 or 12 inch wide range speaker for guitar or keyboard use.

i love the "blue sky" possibilities of having a driver made to virtually any spec, but in reality I like to be able to look a basic example and make some judgements about quality and potential.

as for saha, well I have emailed them, so we'll see. the e-commerce site looks good, but it does seem absurd to use that to order small numbers of parts back into the country of manufacture.

angshudas, thanks for the witty commentary on your trip to track down hunter drivers. 😎

oh and bryan adams was a very tame concert...
 
AM:
Thanks for the tip on PRs, I dont have the time or the inclination to make one by myself, unfortunately. I got one from the US which I use on my powered sub (Lambda Acoustice), and am lo0oking at various options including geting them from the US-it's a little more expensive, but are ready made..
Costs quoted by you for the 12 inch look really low-though I believe in the dictum-what you pay is what you get!

Ashok S
Yes. Saha was originally started here as Kothari Electronic Indistrie Ltd, was a 100% export oriented unit, and made a public issue , then went belly up , was then taken over by Saha and renamed Saha Keil. They have a tie up with Sprague and Susco seems to be their marketing company. I spoke to their guys onmce, but they werent responsive-probably onnly interested in large industrial customers..
 
making vs buying.

Hi George,
I agree with you regarding buying the PR from the market. Depending or location and conditions it is not worthwhile making "everything".
Like the Gaussian curve ( bell curve) "you get what you pay for" also follows that trend.
I have not seen "good quality" cones or other parts in the market. OEM buyers of better materials would not be selling those in the component market.
It is easier to get the right stuff from the US.

Don't you find PR assisted bass units to be a little 'slow' as compared to a good large bass driver ? They seemed to round off the bass though they went much deeper.

Has anyone heard the Wharfedale Dovedale 12 in bass drivers ( from the 70's). They had very deep bass and tremendous 'slam' . I have never heard anything quite like that recently. I've been trying to locate an old pair to measure out the driver specs. I do remember that the suspension of the cone was so stiff that it would not move easily if you pushed it. Never quite understood that because all other bass units at the time were floppy . I wonder if anyone knows about this driver.
Cheers,
Ashok.

What is it? Whats the big fuss?

well I moved here last june and getting parts in india is a big hassle. there are some real fans of good audio here with enough money to spend on great gear, however, locating parts and distributors is a pain. even though some things are made here, they are often not available to the local market.

in london (where I was before here) or back in sydney I could spend 10 minutes on the net or going through the yellow pages and find a swag of places to get the things I needed to build a speaker cab, or small amp. here I'm still struggling to find anywhere to get tubes or caps, let alone good speakers.

I have bought a couple of plate sub amps from stryke.com and am talking to him about a pair of 15 inch PRs for $50, to be shipped to India by post. I got my previous PR this way and it came in fine.

I also have a 12 inch sub in a sealed box, and when compared with the PR version, the latter has more punch and sounds qualitatively better. This could also be because of the better driver and more powerful amp, though the box is almost 40% smaller.

This next iteration( hopefully my last sub-no more speakers also, SAF will not allow any more!) is to have a dual PR enclosure, if I can pull it off. These boxes are quite heavy and I cant easily to an A/B compare in the same room.

My sons have just left for the concert, will post their feedback later. They also went for his show 3 years ago..

Like I said, I havn't been following this thread. It just caught my attention that this thread was always at the top of the list and never went away.


Well the thread was started as the title says 'T/S specs of Indian Drivers' meant basically for those who reside in India and have the difficulty in sourcing drivers with published T/S parameters. The topic expanded to not only drivers but to all components required by DIY enthusiasts in India.

Like all threads, there have been some minor deviations, but more or less has stayed on course. We had fun and made friends, and isn't it what DIY is about.
 
I think maybe we should post only what's relevant to the thread, and not turn it into a general "india info" thread, since mining for info among 25 pages is quite a task. Especially for those on a dial-up. So maybe we should start a convention of some sort, like use the phrase "[INDIA]" on the subject line of any thread we start specific to our country? It makes for a much more readable forum. And thanks, guys, for all the valuable info!

Oh, and who's the screwball who did the mix for the BA concert? Where was his voice??? The mix buried it under a ton of bass 🙄

thanks. i can wait. this weekend we visited a friend who has a 50" plasma screen flanked by a pair of FPM (4" 2.5 way) from B&W and supported by 5 VM1 and 2 10" 500W B&W subs (all driven by an Onkyo 7.1 reciever). This was a small party so i could not delve into system details lest all the other guests throw me out or lock me up.

Anyway my wife took a liking to the WAF. the sound was not audiophile qualtiy. well it was not even good-fi quality (i have my own rating system starting at lo-fi, mid-fi, good-fi, audio-file). very stictly mid-fi.

then i remember Mahendra Palesha showing me some of his drivers (co ax) that were super slim desinged for car doors.

if one was to design back wall reinforcement (incl. rediced need for BSC) into such a system yet with a bit better attention to sound. almost the whole B&W range i find is way to forward for my tastes.

what i am thinking of is a wall mounted, wide range (or fullrange) based speaker that covers 100HHz+. ideas welcome!
 
hi , reply to your efforts

hi

firstly corbato - if it is ashok sahapati had contacted me i have replied to all his mail enquiries it would be best if ashok himself complains directly

the stuff i told ashok about my loan ets was strictly on friendly terms and it hurts to be made fun of

next

i cannot under present circumstances keep samples of - in 8 inch i have 28 types of cones - baskets ets and it will become 50 models easily with different motor structure applications

ready 150 to 250 models ?

with the 3 inches to 18 inches i think ill hve to keep around 150 drivers ready in all types of motor structures

I HAD PROMISED TO SHOW ALL THE DRIVER MATERIALS I HAVE THE CONES - MOTOR STRUCTURES ETC

AND SINCE I LIKE TO EXCHANGE WITH TECHNICAL PERSONNEL ONLY THEY INFORM ME THE SAMPLE THEY WOULD LIKE

my policy is to devolop one driver that goes as an oem driver to a single customer why ? please go through my next post

i had mentioned the batteries as i am getting 400 rms in my car i will be instantaneously be asked how the hell so unless i mention the batteries and a 120 amp alternator

i dont have a listining area yet wher we can hear 400 to 600 w rms as demo without anyone complaining

therefore i mentioned my car

never thought it will become a subject of a joke

as for the taxis its the same case with cars , the roads are p-athetic over here therefore i had advised ashok it will not be possible for a visit to my place and his onward journey to the airport due to the traffic

as i was far away from my workshop and so was ashok it would be difficult to meet up , that was my farsight i regret that he may have had a bad experience yet coming to my workshop in amherst st

amherst st was my service center from my diy days which is yet a workshop my main manufacturing area is on bt road (quite a way in the outer suburbs of cal) -

if ashok can recall i had mentioned this to him when he asked which would be nearest to the location he was at

Hello Suranjan,

Some major confusion here. Please bear with this longish post.

Following your first mass mailer (presumably to all Indian forum members), I mailed back to you enquiring about product range.. I think that was around 2 month ago. That was my one and only email to you and honestly, I never received your response. But I will agree that during those days my email server was erratic. Angshu and George will attest to that; some of their emails were lost too. So I'm inclined to believe that your email too met a similar fate.

But I did try to contact you in the cell number provided in your mass mailer. When I dialled first time somebody picked up the phone, uttered a few words in Hindi (I'm sure it was not you) and disconnected. After several hours I tried again. This time too the person spoke in Hindi and when I asked for Mr. Surnajan, he put me on hold for a considerable time. I could hear him calling out loudly for you. I hung off after about a couple of minutes. So let it be known that while I sent one email to you, I did not receive your response (perhaps due to the above mentioned server problem) and we are yet to speak on telephone. So all this allegation of joking (which none of us indulged in) based on some sort of presumed interaction between us is is uncalled for.
the stuff i told ashok about my loan ets was strictly on friendly terms and it hurts to be made fun of
as for the taxis its the same case with cars , the roads are p-athetic over here therefore i had advised Ashok it will not be possible for a visit to my place and his onward journey to the airport due to the traffic
Ok. I now know why this major confusion. You are mixing up me (Ashok) with Angshu.

So you find Angshu's post, and prior to that may post, unflattering and conclude that we are making fun of you. This Sir is a wrong conclusion and please accept our apologies for any unintentional slight to you. Sri Angshu is a respected member here and his is acknowledged for his skills. I'm sure he too never meant it this way.

Please never for a moment feel that we are joking about you. I’m sure I speak on behalf of others here when I say that we are very interested in seeing you flourish. We appreciate your technical insite and we are reasonably confident that your products would match the best drivers around. Indian DIY scene will benefit immensely from your drivers. We are a bunch of armchair experts (off-course some are exceptions) and find it easy to "joke" about efforts such as yours. But do continue your journey in this wonderful field. And do count on our support.
 
The unresolved questions...

I read Corbato's heartfelt apologies and good wishes, and it's nice to have such humble and friendly gestures on the forum. But I have decided to take a bit less popular path, and point out some of the unresolved questions about the Hunter Audio experience:
  • Two people I respect (Corbato and Angshu) have put in non-trivial effort to get details of what is currently available from Hunter Audio, and have failed.
  • It's surprising to find someone tech-savvy enough to participate on online fora and build terribly sophisticated things like speaker drivers, but not have the knowledge to create a handful of simple Web pages about their products. It needs next to no money; you just need some patience with a GUI HTML editor (e.g. Netscape's Composer function), and a free hosting service to begin with. As a counterexample, see the site created by an enterpreneur much less tech-savvy than the people at Hunter Audio; he designs, builds and sells his own brand of mid-fi music systems.
  • Repeated requests on this thread to Hunter Audio, saying "Please give us some price lists and product model numbers of concrete, specific products" have not resulted in specific product details.
I have no big problem with all of this, but the unresolved question in all our minds is: is Hunter Audio ready for business at all? That's all we are asking, and all this going round and round in circles seems to be getting us no closer to a clear picture on this.

Panda Audio is a good example of the other kind of enterprise.. the kind I feel comfortable doing business with. I have a phone number for their setup which gets answered during office hours reliably. I ask questions about products and get clear answers with power ratings, prices, and availability. If I want to see a demo, I can do that too. The quality of the goods may be mediocre or they may be good, but at least I know where I stand with them. Panda Audio is a small enterprise, driven more by love of audio of the founder than any cash-rich MNC big brother. Panda Audio has reached this point, with an office, a telephone number, a product range, and a Website, not because they are rich, but because they are serious about doing business.

I repeat Corbato's good wishes to Hunter Audio about their venture, but the real million-rupee question on our minds is: whether we should hope to get delivery of real speakers of any kind and any specs in the next... say, 30 days, or should we "come back later?" Can the founders of Hunter Audio answer this simple question? Please? No offence meant here, but if I need to buy something from someone, it's going to be my money, and I feel I need to know some of these things very clearly. 🙂

Cheers, 😀
Tarun
