Well, I've tried to maximize the available space as much as possible by squeezing the hall to a the minimum.
The result can be seen here:
The thing is: I really, really need SOME space in the hallway since the doo is going to the outside, so it will be a place to get wet coats off and such... Plus, I will also have the electrical fuse box (or how is this correctly called in English) over there.
And last but not least, I also need to be able to access the airco units filter for cleaning from there.
So, taking these things in consideration, the plan above is what I truly believe to be using the maximum foorprint while still fullfiling the requirements described above. However, one major drawback is that I can only fit ONE door then, so no double wall isolation there. A second door would simply not open fully... So I was wondering whether this could still be a valid option???
Anyway, starting from there, I already tried to get an idea of how the acoustical treatment could look like. The intermediate result looks like this:
The Good: it's a lot bigger, there is more room for bass-trapping (especially in the back), it has almost perfect symmetry (the back might never get perfect due to the piano and such...).
The Bad: I still have a problem opening up the leftmost window. But maybe that doesn't need to be a problem at all.
And th elack of perfect symmertry in the back, of course.
Here's is a picture showing the speakers and piano as well:
Anyway. I would be very glad with any input from you guys now. Am I on the right track or still far from it? What still terribly wrong, etc... Maybe let's concentrate on the Soundproofing first, since that's the one being built now...
Many thanks.
