DanDan - I really don't wan to poison anything, as you wrote, even if I pointed out in my first post that decay of the main peak at 120 Hz on the very first picture remains exactly the same after EQing as before (contrary to the title saying that it does change). This my argument was simply...

Dear Gentleman, thank you for your effort, I have learn something (mostly that I have to improve my english) - mostly from the original documents linked in the linked threads (but available elsewhere), as those materials contain more or less complete information (with respect to the scope) and...

Dandan, I will try to study and practise more, but I cannot help myself in this - Matthew presented the statement on EQ made by DIRAC. The full name of this tool is Dirac Live, right? In its tech notes, they stated the followings: "Minimum-phase and linear-phase room correction filters can’t...

I feel here some misunderstanding - it was not said explicitely, but the measurement showed decay/reverberation in the room. Based on this, I was expecting that you all are all talking about improvement of the decay of the reverberation in the room, which cannot be reached by IIR, only FIR...

There are two different phenomenons - increase of the SPL caused by untreated modal frequency, which can be reduced b EQ. But the other part - decay of the modal frequency, cannot be shortened by EQ. The IIR EQ only reduce the amount of energy radiated into the room, but the rate how fast the...

Hi Matthew, thank you for your post. I am affraid that there is some slight missunderstanding - soundproof room might be a wide variety of room/wall construction. Here in Europe, lots of rooms have brickwalls or in older hauses also stone walls, with thicknes from 15-30 cm. So if you have this...

Hi all, in my oppinion sayin that EQ does improve decay is simply not truth as only speciffic strong modification of IR of the audio source is able to affect the decay, but usually in limited area in the room (in another area there would be even longer). The first gif showed that peak was...

Hi guys, regarding acustic and soundproofing I can recommend "Recording Studio Design" from Philip Newell, which is focused exactly on this topic (and much much more). Having a room with rigid and thick walls (=soundproof) will create worse initial starting point from a perspective of lowest...

Optimyzing acoustic try/fail basis is a cost ineffective long run. The behaviour of the loudspeakers in the space is quite complex: 1) the radiation efficiency of the lowest frequencies is affected by the proximity of the boundaries - radiation in the free field is less effective than...

I definitely prefer flushed speakers because of no worrying with diffraction, LF reflection from wall and lots of saved space....
