Alfreda Horn Plan 1

Hi fellow enthusiasts.

Hoping you can help me.

A Speaker Guy friend of mine was enthusiastic about the sound qualities of a Loudspeaker design which he new by the name of "Alfreda Horn Plan 1".

The Loudspeaker houses a single full range driver in each cabinet (eliminating the need for crossovers with their inherent complexity & expense) and includes an internal horn structure.

Unfortunately he's misplaced the plans for this build.

Can anyone assist me in locating the drawings/plans of the Alfreda Horn Plan 1?

many thanks

Cliff

Thanks for your instant response 6L6.

Much obliged.

What thickness would you use for the cabinet sheets?

I have access to 19mm "yellow tongue" high density flooring grade particle board.
Is this worthwhile using to assist in elimination of cabinet resonance?
I know a downside is that the resultant cabinets will end up being pretty heavy.


The design looks quite intricate and might be a challenge for my capabilities.

Would you describe this particular plan as the best to undertake for effort vs result?

Also are there more detailed instructions available?
