Products that have a particular coverage pattern and can be deployed to keep sound off the floor, walls, or ceiling are very valuable, and it's likely the TOA product in question works as designed for the frequency range they have some control over. The spec sheet doesn't say where the box loses pattern control, but it's likely to be around 600Hz or so. Whether the TOA product is the best choice depends on the particular application.
The negative reaction here was in response to the posters' desire for a line array, and especially in the case of the OP of the other thread, this desire seemed to be from a lack of understanding of what line arrays can and can't do; rather wanting to have the en-vogue product du jour. I think reasonable skepticism of this product truly being able to satisfy the OPs' needs was the most helpful thing we could do.
As to this thread being in this section of the forum - arguably the OP should have put it somewhere else, but as no one has claimed to have had hands-on experience, I don't think future readers will unduly pass over this box just because this thread was here rather than in the Lounge or the Install forum.
