my speakers are on desk currently with a 25 cm stative so tweeter is on ear height. then woofer cone is 35 cm away from desktop. My stands are Gravity SP 3102 from 26 upto 35 cm. I test when higher is also not good then bass port blow into face.
have a desk with wheels and electric to change height too. so i can test with diffrent heights and position. before d3v i use esi unik 05+ and arc 4 to get more bass direct on desktop. d3v give enough bass also on 25 cm stative. and because of smaller speakers they reach more stereo width because i can put them more outside because of smaller cone. currently i test and measure the focal alpha 65 evo . when i play audio with only left or right speaker with them give really strange feeling in ear and mud bass surround. Have something to do with the angle to the ear. when i put them in front sound better or more side too. i need reach cupboard to the left and skylight window on which i have with magnets add also basotect when i need not open it, so i can not place them on a stative more away and wider. also when i put them more away i need more volume and neighbours hear. speakers are 80 cm away
close bass port work only when it is designed and have a good damped bass. lp6 and focal alpha give more distortion then which is hard hearable. the unik 05+ have a port plug and can work as a closed speaker and get not much more distortion. currently i put the focal on desk and measure and do audio records so it is same position as d3v. with a 32 inch monitor
science tell bass below 100 hz can not locate. but i can locate 50 hz sine and when they have 60 µsec delay between left and right i hear that it is not in middle in headphones or D3V. I really like hear a woofer that is precise. here can see how worse a burst look when record from a speaker. is from d3v and lp6 . there can not see huge diffrence that can explain the much better sound of d3v. it is done with REW osciloscope. you see the signal the speaker get and signal that produce speaker and is record 1 cm away from speaker. burst from d3v
