Looking for speaker grill cloth of very good quality. Searched Lamington road near the railway station, but not sure about their quality. Does anyone know where can I find it? Tried Corrson.com but they do not have.
Thanks

Me too sailing in the same boat.
Have u thought of trying at textile showrooms and/or living room draperies at interior design showrooms.

Will those be acoustically transparent?
Visiting textiles shops is one option I thought about but not sure about their sound transparency...do not know if this is a joke but read in a forum that dopattas (stretchable) in two fold way can be used as speaker cloth.
Also just noticed Parts Express has cloth 1 yard of 70" wide cloth in US$ 7.45. If more people are interested then we can order bulk. I need 2 yards of it. Already asked ICCWORLD for a quote.

You surely cannot buy one that is close woven, but anything that u can see through should be fine. Speakers sound better without one, but bit risky for the costly drivers.

Any cloth u can see through should be fine. No cloth is best, but bit risky for the costly drivers.

Thanks for your kind reply, the NE5532 (or JRC2068D) will be used for gain stage
- but JRC4556 (100mA peak current into 150R) is simply double of NE5532(50mA peak into 600R). The JRC4556 are needed to drive h/p as low as 16 Ohms.SOIP JRC4556 are available in Mumbai but they get hot above +/- 7V.

Yes, that is the main problem. Spent a lots of money, time and energy behind the
open baffle and using it without any grill. Afraid one of these days the maid will poke the drivers with the broom...

Can you share the circuit diagram with us, so it would be easy to suggest you.
You could place a reasonably open metal mesh over the drivers. If made well it will not detract from the looks or performance. I've seen dented dome tweeters cause by the maid moving the speaker around to clean the floor. The cloth grille was on and she had no idea where her fingers were placed. Luckily the owner pulled it our reasonably well with a vacuum cleaner ( carefully!) and is happy that it's been 'fixed'. You can still see some faint creases on the ( cloth) dome. Obviously he is not an audiophile !
But a speaker attack by the 'better half' would be permanently damaging !

Check If you can configure this Op-amp for your need.

I clean my own room as I prefer no grill/mesh/cloth spk. setup. No one else is allowed to clean - seriously
Speaker building raw materials
Hi All,
Thanks for your advices and sharing real life experience. I finally found a website (suggested in some other forum) where one can get things for speaker building. It was very comforting to see this web shop. Here it is:
diyaudiocart
Hope it helps people who likes to shop on the web sitting in the comfort of home/office (like me).

I've been following nwavguy's blog for quite some time(He has stopped updating from last May 2012 though). The objective analysis & measurements plus comments are very exhaustive & in depth but at the same time very "enlightening". A must read for all DIYers.

I've got PCBs for the same from jtkam at diyaudio.(a kind DIYer from Canada who has given away more than 100 PCBs free all over the world with the only condition that 5$ per PCB be donated to diyaudio.com & a postcard to him. Well that might explain my "single star" status)
If any body in Mumbai wants to hear this headphone amp(I'm going to build with smd JRC4556 for the time being), they can PM me.
Thanks,
