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.

Re: Re: Anybody made a Nautilus
How is it exactly dampened/absorbed?
By the walls that will absorb the wave since it´s 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.
Wouldn´t it be like an open baffle-speaker but without the OB rolloff?

Re: Re: Re: Anybody made a Nautilus
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.

An externally hosted image should be here but it was not working when we last tested it.
