I agree, it'll be useful to those who want to take their first (or second) steps into Audio Visual DIY...
Its cool that tooling companies are now using modern project ideas to highlight how cost effective it is to 'have a go' rather than 'get someone in'...
I'll be starting my new Home Cinema/Media room project soon. Its amazing how some of the concepts on this site have exploded into many living-rooms throughout the UK. Its great to see the design process & how the better ideas evolve.
It'd be interesting to poll which is the most popular on the site and to obtain a set of standards, i.e. TV height, distance & basic speaker formation... I guess someone will be motivated enough one day. Lol.
Long may it continue...
