This will not surprise HK Audio loyalists but for the record, they developed the new Elements Install Kit to facilitate simple and inconspicuous installation. It consists of two modified E 435 mid/ high units, including mounting yokes. Up to six mid/high units (including the Wall-mount Kit) may be combined. You can adjust an Elements system on mounting yokes 180° horizontally and fix it in place quickly and easily using the two included hex-head screws.
