Question Need help in T/S parameters for indian made subwoofers..

Hi,

I am new to this forum infact this my fist post. I am from southern india here it is very difficult to find a branded speaker. I managed to get some which had some brand name. Everytime I measure the T/S parameter of the drivers (using my pc) I get the Qts above 1. i dont know whether it is the problem with my sound card. So if any of you guys have actually measured the T/S parameter of YP (Tamilnadu based company) 8" sub or Dainty 6" sub, please let me know.

Thanks,
Venki.

Greets!

Last year someone sent me measured specs for several Dainty LF/sub drivers in an Excel spreadsheet, though 8" is the smallest. Send me an email for the winzip file.

Don't have a clue, he/she? sent me the specs and I did a sim, which apparently I didn't save since AFAIK this brand isn't available in the USA. I'm curious, do you have access to the Indian made Peerless, which is available here?

Peerless India makes drivers only for OEM customers. Some surplus stock might be available in India, particularly Mumbai and Chennai.

I prefer the sound of the Boltons as compared to the Dainty woofers. I made a sub with two Boltons mounted on opposite ends of the box.

Venki, if you want Vifa drivers check out www.corrson.com I bought them Vifas. They are just superb.

Cheers,
Vivek

Hello Vivek,

Thank for the link. It is really useful for people like me who is new to subwoofer designing. I have made few boxes and but i didnt design it i just made it. I am planning to make a 3-way system. But i have no experience with it. yesterday I purhased two dainty SW801 woofers and two MH0508G midrange. I got the specs for the SW801 from GM(thanx to him).
The qts for SW801 is .611. I have seen in some websites that the best enclosure for a spk with qts >.5 is a sealed one.
Is it something to do with the clarity of sound been reproduced.
I plan to make a vented box using this driver. Will this affect the quality anyway?

Thanx,
venki

Hey Venki,
Don't rely too much on standard specs with the likes of Dainty.A friend had bought a couple of SW801's long back and recently we measured the specs.One came up with a 0.96 qts and the other with 0.81.So I guess every Dainty is unique and your measurement(Qts~1) may well be correct.So I suggest do a thorough t\s measurement and simulate in WinISd.You may try a tr line design or an MLTQWT.
Btw how much did they cost?
Cheers.
