What's wrong with Sammy?
At just 165mm, the woofers produce a room-filling, but overly boomy and harsh bass; more like a loud boom-box than the smooth, deep, chest-penetrating low-end that fills a room even at low volumes.
Sammy could have opted for a single 254mm woofer; or even better, a 304.8mm driver powered by 300 watts. That would have truly revolutionized portable audio entertainment.
I guess JBL, ect. needs to answer this call... correctly.
