Hey y'all, my youngest son has turned four, so now 'real' lego is the shizznit. Woohoo! That means Im sitting back with a lot of Lego duplo. I can put it in the basement, pass it on to friends/family (with younger kids than mine) or.. Build a diffuser. I chose the last option, cause why not? The question is, does it really do any thing? Is it too low in height to actually do a difference?
I used this to build it 'right'. But yeah, my 'skyscrapers' are not that high. One duplo brick is about 2 cm in height.

I’ll build some one day, once I find a cheap source for the blocks.
Cause for the amount needed in the same color, it becomes close to wood price.
But still much easier to build, and lighter.

Here you can see some cool ones at 11:30 :

Id-acoustique.com built them, can’t find them on their blog but they were there few months ago.

Nice so maybe it'll actually do something.. Or maybe I need more than just one 'block'.

Excellent - have you noticed any audible change - I am happy in this case to accept subjective impressions. :cool:

My subjective impression would be that my room feels a little bigger, or in other words, that the left speaker (shown in the picture), has a little more 'air' (as you can see; its pretty close to the side wall (which the right speaker isnt)).. So a tiny upgrade to the soundstage. Maybe its just placebo, but i'll use it whenever I can :)

I built some following plans which worked well but looked kind of crappy. I moved to SevenAudio diffusers (and abfussers) which have great finish and sound great.

In now got some lightweight foam ones to use on a removable section covering my projection screen for serious listening sessions.
