Well, the addition of six subs most definitely changes the game for a bookshelf speaker. Does it magically make the Elac perform as a far higher end speaker? Only relatively, not inherently. That's one of the largest problems this community has, a belief in magical transformation of products, such that they somehow jump to a higher level of performance than better gear if only the right ancillary components are selected. It's wishful thinking, and not a good way to build superior systems. Such rigs typically have major shortcomings.
The addition of multiple larger drivers to jack up LF is a valid way to get more out of a speaker. I do similar when I add the Legacy Audio XTREME XD Subwoofers, with one active and one passive 15" driver per sub, to the already prodigiously equipped Legacy Audio Whisper DSW Clarity Edition, which has its native eight 15" woofers. The result? An even more prodigious performance, with presence and articulation in the bass at low level that seems preternatural.
Now, If I were to put in the modest Insignia 2-way speakers that were all the rage years ago (I have a pair I have kept for the fun of it) with those subs, would that magically make them perform on a par with the Whisper? One would have to be completely delusional to think so. Would they be "game changer" in the sense that they somehow were doing as the Whisper does? No, not at all. That's the kind of game that a Chinztiphile plays in an attempt to save lots of money, and they are only fooling themselves. That video is of a gimmick that appears designed to showcase subs, and kudos to REL, as it does. It would be a terribly compromised solution for the audiophile to set up the Elac speaker in such a fashion.
YMMV, and I am not interested in arguing my observations. :)
