Hi,
The room gain subject is not easy to me, at least I know my room is around 40 m² with a plaster half wall in the middle (at around 6 m from the front wall) , bay window on a side, doors on the other side... so very loossy.
My basic understanding is there is some gain in most rooms since 200 to 300 hz, but I am wondering what should be thhe targett of the bass curve when moddeling with (Vituix) whatever sealed or BR (SBB4 in mind if so) to have enough bass for most of the materials (40 hz low end very often).
Is there a minimal targett for the f3 f6 and f10 I should not go below for something not lacking bass according the rest of the (said) flat magnitude in the medium.
I have no way to measure my room gain by measuring outside and substract from the inside measurement to have my room gain curve. Another basic understanding from the Diya page is I should not care too much of the room gain below 100/150 hz and see it has a plus if existing and at the end just move the seat according the most pleasing pressure node (peak and null aka modes) ?
Guidance appreciated please ; I have hard time to decide if I should go vented for low enough or if sealed with big Sd but highish Fs and tunning is good enough for music.
As an illustration, could you live with a f6 at 40 hz for instance ? Noway as I see it to make a 3 to 6 dB low end diving curve without DSP and bix Xmax drivers !
