Default Anybody made a Nautilus

Hello guys,

This is my first posting here.
As you can see, I'm from Germany, so my english is quite bad.

I am interested in a B&W Nautilus.
I don't see any problems to build this thing.
There will be any possible way.

But what about the theory.
Is this a reverse horn, or is this a reverse TML ?
What about the Sizes, Volumes so on ?

I would appreciate some information, if anybody has already
made some theoretical think-abouts.

Greetings

Tobi F.

It is a TL with no terminus -- 1/2 wave i believe... the idea is that by the time a waveform from the back of the speakers can get back to the cone it is completly absorbed/energy dissapated.

This is one POWER DIY project! They look simply amazing - i'm looking forward to
hearing how they finally turned out.

How is it exactly dampened/absorbed?
By the walls that will absorb the wave since itīs bouncing or are the cabinets stuffed with foam or something?
How much would you expect that it would dampen? 100dB?

How will this differ from a regular TL? Performance-wise.
Wouldnīt it be like an open baffle-speaker but without the OB rolloff?

The line shape & the stuffing convert the acoustic energy to heat.

In a regular TL you are using the back wave for some low frequency reinforcement.
