Hello Louis. Welcome to AOS.
I seem to recall the name 'HornUtopia'. It's a shame you could not carry on in the business.
If you continue to have an interest in Hi-Fi, perhaps you could tell us more. Such as what music you listen to and what equipment you currently use.
The private sales area is the Private Exhibitions section. It would be nice if you could participate as an active member though, your involvement in speaker design and building would be of interest to members.
Enjoy the forum,
