I love all the sarcasm here

his opinion is ok for the point when not want a subwoofer or a butt shaker or never want try out diffrent EQ settings and want easy compare which sound best. to get better sound out of subwoofer is usefull to have it. I also need delay my main speakers to subwoofer. I have no real subwoofer and use the jbl 104 as near field monitor 70 cm distance because they are coaxial and have the best directivity steareo image at this distance from all speakers i have. so i use the focal alpha 65 as the subwoofer back on my desktop and on the wall.
because there can not read much about damped room results i write much more to explain better.
I have damped my room around 2.5 meter width 2 meter height front and back wall and 3.5 meter x 2.5 meter ceiling with 5 cm basotect. my room is L size and i do only this region. this i find is key to HIFI heaven. on side i have very few damped. room sound not dull(this was my gretest fear) and bass is much more clarity and tighter and even the boom bass range i like. damping bring so much better sound, even when in nearfield 70 cm away and even my not subwoofer speakers are more than 70cm away from walls .I do not more, are ~18 qm damp material and cost around 380 eur. my whole room is 17 qm do all cost alot more money. but because of my tracks dsp i can get this 3 speakers work good together.
without the ability to compare diffrent correction i was not able to reach my hifi heaven. my subwoofer is around 1,8 meter away and speakers 70 cm. before i damp i hear that bass come from more behind even at low crossover freq. but now it is tight and great. also the jbl without sub sound as if it has lots more bass as before.
here are my dsp settings and the FR i get. because all together give the resulting sound i can tolerate more eq and diffrences until it find it bad in compare to headphone. now i think headphone are worser in compare and so i have hifi heaven . about the FR i think it is only around 4 db precise to measure. to get better precision need compare with headphone and look if the peaks in the measures in music are really louder as in a measured headphone or if you can hear a diffrence. i dont trust multi point measure software. but i use math room roomeq and measure and compare the diffrences. use dsp only and wide Q eq give better clarity
this is the jbl 104 without sub and no EQ. measure was not on same day a little diffrent microphone pos so fr is not good same as before
