KlipschRC-62 II Center Speaker Black - Each

Hi,I am electrical engineer, so know something on frequency, crossover, response etc. Not an audiophile, but assume I have good ears. I undergo audiometry tests regularly for official purpose. I also have the habit of reading the posts on speakers which my family hates… knowingly that I will not buy anything new.I had KEF LS50, R200c, wharfedale diamond subwoofer home theater along with Klipsch RF62II, RC62II (changed from RC52II to RC62II), RS42II and SW112 subwoofer (crazy…). I gave the KEF setup to my friend as over the period of time I found the Klipsch was more suited for home theater with bigger fronts and center and of course horns, higher efficiency for the impact. I found KEF LS50 was not satisfactory for home theater. R200C vocals was good or even sometimes better, but was with less bass (tiny) compared Klipsch RC62II.I do see these comments on the Klipsch RC62II that it is boxy, or tin-can sounding, or vocals not clear which I also experienced. Especially this was true for some male voices. So, I wanted to share my experience thinking it may also workout for others and eventually useful. In fact, I have taken RC62II to near by Hifi shops having theater and there when connected blow everybody including the seller who is dealing with speakers day in day out. I also understand RC62II is not the limit but you may need to go for much larger size which do not fit in living rooms.I saw the frequency response of RC62ii measured by sound and vision. I observed that it has dip (-3db) at 2kHz crossover region and bump (+3db) at highs. So, with AVR (Onkyo TXNR 929) I did the following after running Audyseey for center channel.1) XO at 120HZ to remove lower frequencies (still some go to center at 12db/octave) and diverted to subwoofer, other speakers set at 100Hz, LPF for LFE at 120Hz.2) In Manual Equalizer, I changed 63Hz at -6db, 2.5kHz at +2db, 16kHz at -2 db. Rest all at 0db.3) Speaker levels for all speakers set at same level (no bumping for center).4) AVR played with Audyssey OFF, Dynamic Eq ON, Manual Eq ON.5) Remove the grill while watching as these are very thick.With the above changes, I find the vocals have improved dramatically (very intelligent now) and also no more boxy sounding. Sound stage is a bit wider too. Further tweaking may or may not make it better, but decided that it’s enough.I find that, by little tweaking we may be able to make the satisfactory outcomes. So worth trying based on individual circumstances. Also, I don’t see point in changing the speakers without trying these.I thought this may be helpful for others (similar exercise may work out for other brands and models also), so have posted this. Good Luck.
