What I was getting at, mastermaybe, is that its limiter kicks in at a point that I thought was overly conservative for the price and materials used, creating a situation where output at and below 20hz is limited to ~105db, dropping significantly thereafter. I'm specifically referring to the compression sweeps. Of course I read the entire article (including everything else you pasted) prior to making my original comment.
The implication was that, given the price and size/shape targets, do you not think a dual-opposed system with larger drivers could be engineered to have higher dB at lower extension output, fewer mechanical parts, the same vibration cancellation, and the same feature set, perhaps even an enhanced feature set due to simplified engineering?
By all accounts, it looks to be a fairly serious performer, but I wonder how much more could have been accomplished within the engineering targets given a slightly different design philosophy.
As to your commentary on "how much is enough," well, no offense, but I think we've all read it enough times in enough threads that we get your perspective. I think it's time to let that one go, bud. It's tiresome to have pedantry so forcefully and frequently put before us and, most importantly, it stifles debate. You set up your opinion as unfalsifiable; how could/would anyone deign to argue with you? Have you considered that people will have their own perspectives that differ from yours, and that no amount of browbeating will (or should) change that?
