normaly left and right should not merge. the measure for bass can not trust in a room. because in reality you hear for kick drum much more bass. the room modes that measures show happen not on kickdrums because the first waves get not reduce by room modes. see my burst result. first is the room mode at 53 hz on left speaker. you see that only later the level go lower. enough for kick drum. and the room modes that boost 160 hz have less transients, because go only after some cycles higher because of room mode. thats reason that automatic speaker measurement always make bass too loud on FR valleys and too silent on FR peaks. here you see how a kickdrum look. first come highfreq then lowfreq 1 cycle only then it decay. thats short enough that room modes can not affect it

this is 53 hz burst with microphone on my hearing position. the D3v have at this frequency a valleybecause of my room mode. but you see in the burst the first cycles at 53 hz have good level. only later get lower

I get the best results with the d3v and other speakers i notice now when i use a match EQ and use the orignal testpiece as the target . and the match EQ should calculate the Eq so that the testpiece record of the speaker sound much more near same as original. this is the result the match EQ get und in compare to calibrate headphone sound better as arc 4. not too much bass as with arc 4. because the match eq see how much bass the recordet kick drum really have. it is also ok for bass play because seem ears like transients and if later the bass more decay doesnt matter for me
the mfreeform allow also easy change the smoothing .change the smoothness knob and klick equalize. and with the range knob you can choose the strength of the EQ. 24 db was normal. when reduce it to lower as 24 db then less EQ is used. it can work phase linear with latency or minimum phase wirth no latency .there are more match EQ plugins. ozone, smart eq
