Default Rega Naos internal design/layout

I have a set of drivers for the Rega Naos speakers. I was wondering if anybody knows any information on them. All I know is the external dimensions and that they are a quarter-wave TL design. I was going to use them in my own design but I don't have test equipment (as of yet and in the works) so what I would like to do is try to stick close to the original design. Any info would be greatly appreciated.
Thanks
Fred

Hi,

An educated guess is internally they are very similar to many designs.

Internally the may look like this : (except with a rear opeming not top)

An Extremis 6.8 Offset Reducing Taper TL Design

Or likely very like this :

With the external dimensions you will not go too far wrong.

A friend had a pair of Naos. Pretty good, but not in my book for 1K.

You will need the crossover details.

Thanks a lot for the info, that was the way I was leaning, but... Where is the port opening? In your post you say not at the top, but how do you have a top mounted driver, one fold and have a different than top port (or do you just mean at the rear, like in the second design).

I figured it's worth a try, I got the drivers cheap enough.
Cheers,
Fred

Very little right now,
I am kindof taking it one step at a time, but I know they used a very simple crossover design.
With your suggestions and some more searching, I have found enough info to put together a rough design for the box anyway.
Thanks
