After owning a pair of Heybrook Sextet Mk 1Vs for over 20 years I decide it was time to externalise the passive x/overs.
There was a thread from the old WAD forum, not much info on what the internals were like but a definite endorsement about doubling the filler material for the bass chamber.
I have some blanket type material used to protect furniture when moving. It's made of various wool, man made fibres etc. It seems very suitable for the purpose of applying to the walls of the bass chamber.
The Sextets have two chambers - one for mids and the Tonigen tweeter and one for the bass. The construction of the bass chamber is about 2/3rds of the total cabinet and consists of a bracing bar half way leaving about 50cm on either side of the bracing bar for the sound pressure to enter the two ports before exiting.
Should I use this material on the upper section of the chamber or the bottom section. I will use fixative to hold the material in place.
Also should I 'cover' all 4 walls?When I removed the internal x/over I replaced the empty space with plywood to fill this space in effect creating a solid wall.
If the rec. is too use this in the bottom half of the chamber I can remove this plate to access the bottom half should the material prove to be a negative. However the top half will mean removing the SEAS woofer to access the top half of the chamber.
