At this year's CES, Magnepan showed how their smallish bass diaphragm panels could serve in place of the larger Timpani panels from years back. The presentation spoke to customer concerns (well, mostly customer wife concerns) about adding additional large panels into a room to improve low frequency balance. The bass diaphragms were on display, not hidden behind a screen - you might have overlooked them as one was disguised as a small side table.
Overall, they took more of a conceptual perspective on bass response and room integration rather than a product-selling focus. While Magnepan like to give a focused rather than free-for-all presentation, I had absolutely zero sense of rudeness - quite the contrary. And the sound was excellent.
