Plinius+Harbeths+Eichmann

can u give me a link. and can u source them in india or better, in bangalore.
25$ is very very affordable. also do u have any idea how much i will have to pay as duty/customs if i have them imported .
of courcse i will have to take into consideration the thiel/small parameters while choosing them.

spoke to the Jbl guys just now. it seems they supply replacement drivers only to their customers and hence cannot help me.(was eyeing the drivers of the Northbridge e100). somuch for that.
if there is anyone in this forum with the Jbl speakers (which have 10 inch drivers) please help me in this.
thanks,
Benks

BTW the driver is around35$ according to the website.

locally , I can think of one option for you..peerless india based in bombay.

Their website address is peerlessaudio.com

Write/call them and see if they can help you out with a dealer in bangalore.

manek.

i know about peerless audio. Mr.Palani from audio planet(Torvin) deals with them . he can source them for me(he actually made an offer to me regarding them). but from what i gather from diyaudio.com the chaps say that the t/s parameters are not properly quoted and the quality is barely satisfactory and hence my abstainence.
Benks

If you want I can courier it from here and you can pay in INDIAN Rupees. All I need is the site from where to get it.

A word of caution, each driver has a particuliar Vas, Qts, Qes ect....known as Thiele Small Parameters. If you give me the name of the driver or even your old speaker name & model number...I could perhaps be of some help.

junia can u tell me how much duty/customs i will have to pay.
i know abot the thile/small parameters. if i know exactly how much premium(duty/customs+freight) i will have to pay for say a total of 80$ then i can think and decide. and where are u put up presently.
Benks

Hey this is a good way to see if the Underwriting stuff will work or not !!

Jokes aside, the least I can do for this forum is to send you stuff at cost.

I am based in the US.

Feel free to let me know what else you want.

Junia.

benks...peerless audio makes drivers and speakers systems for Acoustic research, JPW, Heybrook and many others on a OEM basis. Yes entry level products, I agree.

Sonodyne speakers use peerless drivers.

BTW Peerless India also make full frequency high end drivers for one of the Rethm line of speakers.
So they could not be that bad. It all depends on what quality driver is availble in the market from peerless.

About incorrect TS parameters you could be right but do remember, DIY guy's who have measured drivers usually come up with different TS parameters. Most of them dont have anechoic chambers and hi-end microphones and measuring benches like the companies do.
I have read about Vifa drivers P17 6.5" polypropylene drivers been measured by DIY guys and they measure very differently from the TS parameters listed on the website. For example the Fs listed on website is 37hz. What the DIY guys measured was 42-44hz. So are we also saying that vifa are stating incorrect parameters ? maybe not. Most speaker manufacturers re-measure the drivers with their own equipment and then design the speaker to keep readings in check and consistent.

I guess it all depends on under what conditions and how accurately the measurements are re-done as well.

I think Corrson could import vifa/scan speak drivers for you but you have to work it out with corrson. The next best bet to my mind is still peerless india. I dont know if you have the facility to measure the drivers but if you dont you have to rely on manufacturers specs.

Manek.

thanks for the info Manek.
i'll have this go over at diyaudio.com and see what kind of drivers i can get here in bangalore.BTW do u by any chance know what they retail at in Mumbai.
regarding the t/s parameters. yes it is true that the vifa p17 woofers have different t/s parameters and also differ from their printed sensitivities by as much as 2-3 db(less ofcourse).i am planning to construct a new baffle aa solid one from Mdf(atleast .5 inch thick) to replace the one present so the type of mounting required for the woofer is not of concern.
i tried corrson, but said that they were unable to do so and have only the p17(thier high end models). maybe Prithvi can help me out in this regard. but i guess the vifa would work out to be a bit more costly than the Peerless.

Dear Manek,
I use Leap http://www.linearx.com/products/software/LEAP5/LEAP5_01.htm
and http://www.linearx.com/products/analyzers/LMS/LMS_01.htm for all my speaker enclosures. No special rooms are required.

As a matter of fact the above software is used by Dev Kumar (Peerless) himself....I bought it for him a couple of years back !
Regards,

Junia.

does anyone have the loudspeaker design cookbook by Vance Dickanson. i tried British council but no luck. i would like to borrow it and get a xerox copy for myself. also does anyone have the amplifier design book by douglas self.
BTW i am using Win ISD for designing the speakers so i'm inputting the box dimensions and then choosing speakers which will fit into my present cabinet. a great little piece of software.

Benks

I have it in my Bangalore house. I think I can dig it up. which section do you want photocopied ?

I thought you said you lived in Bangalore. If so if I have your telephone number, someone could contact you, if you want to have a look at my DTY books on Amplifiers & Loudspeakers.

They are a whole stack of them

cool.
i want the whole thing.
there are a couple more books( i have to check which ones, i had the webpages saved somewhere).my number is 23220842.
do u know Prithvi. if u do can u leave it with him.
Benks
so u are out of the country. USA?

off to gym. see u guys at 8.30.

JSA,

thanks for the info. I've been to this site before :-)

Does that also mean that benks fears peerless india and incorrect TS parameters are unfounded ? If so then it would make his task much easier.

Manek.

Dear Manek,

As you are aware that TS parameters are dependent on a number of factors that go in the manufacture of speakers...be it glue, spider suspension, rubber surrounds, maganet strength VC windings etc... The matter is further compounded by humans being intricately involved in the manufacturing process. It make it really hard to have a consistent amount of glue or ferrofluid put in day in & day out among the entire production staff for the similiar kind of drivers manufactured.

What speaker manufacturers normally do is to give an average TS parameter for the entire range...which unfortunately can be 100% off the true value. Whether it be Peerless or Dynaudio or Focal they are follow the same procedures...I have been to their factories & got it out of the QC mangers themselves !

It really depends what kind of system Benks is looking at. If it is a closed box, the speaker system is far more forgiving in variations of TS parameters...he would only have to go in with a speaker of a higher Qts. The Peerless 10 inch is a perfect speaker because of its high Qts. If he is looking for a PR or Vented system then he is in a spot of bother as the Qts has to be low and he would have to match the speaker parameters. Perhaps the 8 inch Peerless drivers would match as they have a lower Qts...he can get around the high Vas & lower power handling capacity by going Isobaric perhaps ??!! :-)...he is reducing his Vas by half after all !!

That is one side of the story ...then there is the crossover....that we shall get into another day !!

All said and done Peerless drivers are good, but depending on what the application they may or may not be matched....also it depends how finicky Benks is !! :-) !!

Junia

Dear Benks,

It might be a good idea to check the books at my place they are a bit too many to cart around. If I remember right they must be 50 to 60 DIY books.

Whatever you want can be photocopied.

Regards,

Junia.

hey junia,
that's righti am going in for a closed box as i like a tight bass than a loud one. by going in for the closed box i don't need to bother about the port dimensions and port velocity, no of ports,rear or front firing. i will definiteley be going in for a 3 way system. i know the crossover is going to be crucial as a 3 way system Xover is more difficult to design than a two way.does peereless india have any speakers which have a fs of 35 to 45hz. i want the freq response in the low end to be 45hz, atleast. how much would these cost. can u hook me up with someone regardinig this. price is definitely a factor and the fact that i can get them in bangalore(india) will make many headaches go away.
thanks for the same.
Benks

whom do i need to contact for the books. my nuber is 23220842.
benks

I am going to give you a call right now

sure . go ahead. i'll wait.

junia the pleasure was all mine. thanks for all the support. will keep u posted on things. thanks for the links

jsa,
Talking about the Ts parameters being the average of the entire range....am not sure what you mean.....do you mean an average of an entire batch ?

Yep, I get your point about the manual procedures and the variables like glue and stuff.

manek.

jsa,

Yes, My mistake earlier, the Ts parameters i believe are usually measured with the driver in strapped in some sort of a vice.

The FR chart given uses chambers, mikes and stuff.

Manek.

Dear Manek,

I wish it was for the entire batch...I think it is for the whole product line existence ! Think about it, once it is printed in their fancy brochure, they would want to stick to those values no matter what happens on the shop floor LOL !!

If you can pull some strings & select from a batch at the assembly line...that is a different kettle of fish.......

Or some sites do offer matched drivers (with an individual TS sheet...which they have matched) at a exorbitant price.........if we had deep pockets...that would be the best way to go......

Dear GazzaNZ,

It is great to have you on this Forum !

As the designer of Plinius amplifiers could you please let us know why in the SA Reference manual it is mentioned that the amp would prefer speakers having impedances above 4 ohms ?

They are other popular brands having similar ratings as the Plinius integrated 9100 & 9200 why is there a difference in pricing....in other words what is different with Plinius. Isn't a 100 watt a 100 watt in what ever package it might be ?

Thanks,

Regards,

Junia.

Dear Manek & Roshan,

Bombay & Bangalore it will be ! Would Andheri in Bombay & Cox Town in Bangalore be appropriate places ?

What kind of gear needs to be demonstrated the entire range, selected few ? If so which ones...mid or entry or top of the line ?

How can the equipment loaned be safe guarded for someone else to use...we were thinking of having someone install & uninstall the equipment at an audiophiles place and take a post dated check with a signed agreement...after verifying with the bank that the check has come from an account that is at least six months old...can you see any holes in this ? Would all this prove to be too cumbersome...if so what steps could be taken that would provide safety yet flexibility for an audiophile to experiment with the gear ?

Is thee Duty only 5% ???????????? That means if equipment is got in a SKD or CKD form there is only 5% duty ? Man if that is so that is the way to go ! As to Exports is a buy back commitment mandatory by law or is it from a break even point of view ? If it is break even, then there is no cause for worry. We are not looking to make a profit from day one....but to be for the long haul and built a loyal customer base. I tried my hand at getting rich overnight selling audio gear 10 years ago and got burned badly ! I am older & wiser now and feel the key to long term success is to put ones selves in the customers shoes and get decent products at affordable prices with maximum flexibility...and you guys are helping me achieve just that !!

Thanks,

Regards,

Junia.

Hi Junia,

The SA-Reference manual only refers to "average impedance". It can drop quite low, 1 Ohm or so would be OK at some points on the impedance curve. It has alot of current capacity.

The same applies to the other amps, including the 9100 and 9200. They can drive difficult loads as they have plenty of peak current capability.

Regards

Gary

Dear Gary,
Its great to have you on the forum. Welcome. Now the indian members can know more about your fantastic designs products

JSA,

I think if you manufacture stuff in ckd's then there is by law an small amount of export you will have to do.

About getting rich overnight, That only hapeens on the stock exchange I was told...not in retail :-) Just kidding.

This long term view is a good one and very re-assuring for the customer.

Andheri is a big suburb and definately an option. I've been looking at most of the hifi shops and the few that do decently well are in a commercial business areas. Malls I believe have a lot of rental overheads though Bose seems to do well in malls. Bandra would not be a bad option either. You should look at a place where you dont get 90% women window shoppers cause thats no good. Thats where other outlets are facing problems....wrong target audience gets into the shop.

Another thing to think about is to keep the shop open sundays so that working people can peacefully spend time on a holiday exploring their options...(this is my view only).

I dont think COX town in Bangalore would be an ideal place. Some where near MG Road, Infantry Road, Koramangala might be a better choice .

Best regards
Deepu

Dear Manek & Deepu,

Hey I thought we had agreed to set up stuff in an actual living room in a real life situation ! Yes the places will be open on Saturdays & Sundays.

About Cox town, I have a place in Koramangla...with the road dug up....it is crazy ! I thought to temporally move the gear to Cox town...there is a huge living room there before I put the stuff in Prestige Exotica...that would be ready in another few months time

Thanks,
