Is high frequencies with this speaker? I use TPA3255 Ayima 07 (Meanwell power supply) with no correction and feel lack of high frequencies. I heard it with MS6S in soundroom and feeled some lack of HF. I listen at hom now.
Maybe it is signature cause I even heard it through youtube on 660S comparing to Genelec8351.
But is there recommendations to get more HF?
Listen to them On-Axis (Uni-Q tweeter pointing directly at you) and you will get a very flat high frequency response (which could be for too much HF for some people).
I listen to my R3 without Toe-In looking straight, because I prefer that wider soundstage instead of the focused presentation that toe-in gives.
And to compensate for that High Frequency roll-off I’ve set the AVR tone control to +2db starting at 2,4kHz.
This are R3's in Stock form, no Toe-In, listening position at perfect equilateral triangle, R3's acoustic center spaced by 253cm, Mic 0º at listening position. SVS SB-1000 Pro with 3 built in PEQ active.
And here the same thing but the Tone Control in AVR activated, and the SVS sub level raised by 2dB.
Analysing the graphs, its possible that the top measurement was done with wrong mic cal file, because the HF difference is bigger than what the Tone Control should do. Mind that this is the very first week with the SVS sub and this measurements are the result of a first one day integration attempt (which still looks quite good for the low effort).
My advise for better measurements without much disturbances on HF, is to push the Shadow Flare inwards, measure on listening position where an exact equidistant triangle forms with the speakers, use 0º mic at ear level facing to the speakers, take away your couch, sofa, coffee table and anything that's on the way of the listening position and is not a really big fixed furniture. And don't panic about shit coming out of 1/24 smoothing, go for Psychoacoustics/Variable or 1/6, 1/3 but don't go lower than that.
