Suffing T-Line Speakers

[timc]

Hi All,

I am building a pair of Transmission Line speakers.
I am following the basic rules of thumb, but have
come to the very grey area of stuffing...

I know wool fibre is very popular for stuffing, but
I have chosen polyester/Dacron for budgetary and
Availability reasons.

I have seen several sites on the web that give some
hints of stuffing with wool fibres (fairly lightly stuffed), but not much about Dacron. I have stated with a
lightly stuffed line and added stuffing to tighten up the
bass (to my ear).I know that using Dacron requires more
stuffing that wool, but am worried that I am over stuffing
it. The stuffing is getting quite tight/squashed in.

I am however quite happy with the sound!

Any help greatly appreciated.

Regards,
Tim.

Then what's the problem?
You don't plan on listening with anything but your ears, do you?
If it sounds good go with it.
Of course, I know nothing about stuffing T/L speakers.

Timc:

Have you taken any measurements on your bass? Use your computer as a speaker tester. This site has links to programs so you can see how much and how smooth bass you are getting out of your transmission line. Look around the net and see other places for test equipment if these don't suit.

Good luck!

What's Dacron anyway?

This is very basic question...

What is Dacron?

I live in Indonesia, and it's very hard to find audio kinky stuff around here.

Is this speaker-filling-Dacron the same dacron that is used to fill our sleeping pillow?

Thanks!

I think the biggest difference between 'Audio Quality" Dacron
and the Dacron used in pillow stuffing is the price!

They are the same material, some might argue the quality is different, but to my eye they look remarkably similar.
I would just use pillow stuffing at less that 1/4 the price.

Regards,
Tim.
