All the speakers I made - suri

[iaudio]

Now thats settled! So now you have to build a movie sub woofer for your wife's home theatre.

yeah, sure - i took that to heart!

 

[suri]

And here -

probably my last project before i decompose in my burial vault-

"The Cannanore Royale"!!:lol:

And have you selected the plot of land where the vault will find residence.And have the neighbour's there been 'sounded' about your audiophile predilections?

the plot has been selected - it is where i grow my tomatoes and chillies and karipatha- and also where i plan to put up my (moonshine) still-

and here in this burial vault - there will be I (decomposing) - a pair of "Witches of Ecstasy" - a 2 terabyte hard disc filled with music by GeorgeO (playing in continuous loop mode) - german-made electronics (which will have fail-safe play mode - in the sense - that in the event of a break in the supply of electricty - it starts off where it stopped)

all this supplied by (Cummins) auto start/stop generator-

BUT -

no sub-woofer - (do not want my decomposing bones shaken too much)

that is why i do not see neighbours being disturbed by my thesis support work.

i know - i know- got to make wife commit to keeping the diesel topped up in the generator - will need to add a codicil to my will

LOVWLY .... sorry, lovely polish on them speakers. You did it?

LOVWLY .... sorry, lovely polish on them speakers. You did it?

there are sixteen coats of clear lacquer on them - i tried my hand on the third coat and ruined it (excess lacquer and it was a mess).

after that i did not try and the "expert" completed the job

hehehehe hemanthwaghe!

my home theatre journey begins today - for wife - who watches movies -

By null at 2010-10-08

to conceal the wires

By null at 2010-10-08

the room is 17 feet long and 13 feet wide with a 16 feet high double slope ceiling.

except for the TV - and the main front (pair) speakers - there is nothing.

Nothing I see a PS3 there :licklips: :clapping:

Flooring is done superb .... :clapping:

hi kittu1977,

after reading your comment, i realised that PS3 can be used as a blu-ray player!
thanks!

the witches of ecstasy now have a veil to cover the drivers-

By witchesofsound at 2010-10-23

WITH THE VEIL

By witchesofsound at 2010-10-23

AND WITH THE VEIL LIFTED-

mainly to protect the drivers from ambient dust-

Suri, in Witches ko..."Parden mein rehne do, parda na uthao, pardo jo uth gaya tho phir dhool ghus jaayega'.

What about a fence at the bottom to protect them from the affection of the furry trinity?

yes, the pictures are disparate - but at the end i will post a diagram (hand-drawn) about the working of this sub-woofer -

and after being pressed and jointed-

By witchesofsound at 2010-12-01

By witchesofsound at 2010-12-01


this is designed SPECIFICALLY for personal-home-theater and not a mish-mash of pro-audio for this purpose -

the design is meant to realise the enormity of subtle bass for orchestral music and also the immediacy of (large-scale) personal home-theatre -

it is not designed - of course - to batter and bruise the innocent listener.

and yes - they have a name -

"Witch Heart"

 

[grubyhalo]

Very impressive!

 

[suri]

the structure is complete - looks as ugly as sin ("witch heart") - i should hope that it works -

this is a transmission line air-coupler - to work between 20- 50 hz - home theatre mainly -

no, i have not used MathCAD worksheets from Martin J. King for this (yes, i could have had it done for me) - but, really, i believe that all that simulation using software (written not by god, but by {fallible} men) only leads the self speaker builder to the road that leads to crap - and i should know, because i have followed - Zaph|Audio - and ended up with loudspeakers that were not very good -

i now believe that, while mathematical models and simulations are good (for non-transmission-line speakers) practical knowledge and first hand experience with materials and the way to put them together while making the cabinet is the "deal-maker"

for transmission line loudspeakers - the behavior of mid-woofers/woofers/sub-bass in such a system is not "in-the-clear" and, i would urge readers not to follow martin j. king - there seems to be a big (black) hole somewhere ( and here - there is a 'wise" saying - "IN A LAND WHERE PEOPLE DO NOT HAVE NOSES, A MAN WITH HALF A NOSE IS THE KING" - cmsajith will recognize this - and looks to me that martin is the man with half a nose - and we all are without noses!)

Hi Suri,

Skepticism is all to the good, and is certainly required as far as commercial speaker designs go.

But give Martin King his due. He is not at all commercial, and has made his work available to the DIY community. There is plenty of merit in his work. The fallacy is with users believing it to be the absolute truth. No model or simulation can be that. It should be used only as a design tool to get a speaker going.

Doing it yourself is the truth! After all, it is in actuality in front of you. And, in truth, the only person to be satisfied with the design, is you yourself!

Regards,
Viren

OT- Had been to Suri's place last week and had a listen to his speakers and also had a Dekkho at the WIP on his Witch Heart..

Totally agree with Viren, Martin's worksheets have been around for about 8 years, getting constantly updated in due course. These are highly regarded as well due to the proximity of simulations to objective measurements.

hi Viren, (while there is merit in that person's work)

a healthy dose of skepticism is due (here also) for the following reason -

1. This is the work of one man - and others (one exception) have not tried their hand - why have others not put their efforts into understanding the behaviour of transmission line systems? - is it because it is too much work? - is it because it is so complex that reliable simulations are very difficult?
are people applauding the work because they cannot really understand his understanding of transmission line loudspeakers?

and after all these years - not really satisfied with my own designs either
- i think i might be better off designing a better room! -and leave loudspeakers (and their attendant compromises) behind.
