Yeah i suspect Kali might actually go a little louder then the Elacs due to Elacs low sensitivity, I should ofc listen to both but only way to listen to the Kali's for me is to buy them, which is always risky. I did enjoy both UBR62and DBR62 from Elac so advantage there is i know how they sound.I would choose the Kali over the ELAC due to power handling for HT, however the ELAC wins in dispersion width which may be more enveloping.
Surrounds that work for me are lower-profile (so no one runs into them) yet still powerful. I find the Polk LSiM 702 excellent. See if they can still be found.
Thanks' for the comparisonSee my size comparison:
IMO, IN-5 would be fine.
