Dear Community,

after arriving back from a 2,5 years business I'll have time to rejoin my hobbies as well. In general I am satisfies with some of my historic devices As I am new here some introduction what I developed in the past. As I mentioned it's some years ago and I am actually prepare a windows pc to install clio for measurement and treeing to adapt old knowledge to get back on track for measurement sessions.

Ok, coming to the point. I want to rework my cabinets of front speakers which are burden of my past :-) and perhaps take the opportunity to enhance the quality a bit. In general the cabinets form of the DD6600 would fit for my visual expectations with my Tractrical horn which is heavy ca. 45kg. The goal is that I will not loos my 2 babies :-)

Here my questions:
1. What do you think about the components, partly historical?
2. How can I optimize it? -> some ideas?
3. Should I keep the active speakers or should I switch on passive?
4. Does someone of you knows owns some special knowledge or have some ideas how to integrate something like this with an interesting optic?

I believe, it could be a interesting discussion started here. What I read here in this forums threads is very, very professional and a lots of great ideas are here as well. I will post more pics soon if your interested.

Many thanks in advance
