Elac B6 Modification

jayctoy,  to directly answer your question...I haven't heard the mod that you posted about,  but I can look at curves and tell you what something will sound like... the mods that I posted above will be noticeably better... even the 1st mod listed which would cost you very little....The difference will be a livelier top end with a bit of added detail.  Good luck with this guys,  this is an easy modification and well worth the money. By the way on the link that I posted above Andrew Jones chimes in about the mods on his speaker... worth the read. 

Danny Richie offers two levels of mods for the Elac speakers. It corrects a few of the designs weaknesses.

Nothing can mod that square box though. 

The box is a rectangular.

The enclosure is not only very lightly (to put it charitably) braced, the MFD it is made of is the less dense and stiff variety. But hey, it's a budget product built to a price point, providing sound quality above what you'd expect for that price. The parts quality is also rather low, but Danny Richies mod replaces them with higher quality ones, while also improving the speakers frequency response. Whether the mod is worth it's price is for the Elac owner to decide. That topic has been discussed on the AudioCircle GR Research Forum, where Danny provides info on the ELAC mods he offers.
