Thanks revtech

Btw can you give me an idea about the price?

i see problems ...

1. there is no stereo seperation!
2. the box is made of box board- it will flex like no tomorrow
3. the box cant be sealed as the wire goes in the front
4. expected box volume to be around 10 liters for 2 6x9s. peaky bass but the box is soo lossy that box loss will compensate and make he bass less peaky at the cost of extrension
5. are the speakers screed in? if so the "baffle" does not seem to be.

What does CCTB stand for? Closely Coupled Tape-board Box. I cant even begin to guess. If this box makes good sound I am Sam's Uncle.

The boxes on this link are most of box variation i know

I dont know anything more. I am at a loss for words. All I know the photos were taken using a Sony digicam.

Now i know this is Sam's real surprise! :-) LOL

Corrugated Cardboard! ha ha ha ha I dont know if I should laugh or cry! I am confused. TO paraphrase Ray Davies.

"Well I’m not dumb but I can’t understand
Why it walked like a woman and talked like a man....
...Girls will be boys and boys will be girls
It’s a mixed up muddled up shook up world except for Vivek's sub"

Vivek is a madman!

what is the box tranmitting. :-)

Vivek you really ought to get nicer boxes using alternate layers of 4mm mdf mated to 6mm ply; sandwiched with lead and resin bonded fiberglass. trust me nicer boxes will make sure you only hear the driver and not the box. Boxes should be about 20kg per cu. ft. these look like they are about 200gm per cu. ft.

I think you've seen them on the diyaudio.com forum.

Technocrat · 11th October 2005, 16:17

Thanks revtech, I think they are slightly on the higher side but will still check them out :-)

A coupled chamber tuned box is another word for a tuned isobarik box. if you look at the link below look for 4th order bandpass, double chamber isoabrik. this box consists of 2 boxes.

a) the isobarik coupled speaker Vb1
b) the tuned box Vb2

Coupled Chamber Tuned Bass? Closely Coupled Tape-board Box? I bet Navin was really shocked. This is hilarious.

I had better get the parcel tray. And quickly.
And yes Navin, I have seen better the stuff you are talking about on diyaudio.
