And a good example of an underhung motor design. It can be bettered. As in the motor can be made a little longer and the soft parts made to accommodate a greater excursion capability. But that stops being realistic after about 40mm one way excursion.I didn’t know (and don’t care) how much the Magico costs - it looks like something a bomb squad might use to safely detonate explosives, not something for a human living room. I only mentioned it as one of several examples of commercial products using a specific brand of drive unit.
However, your assertion is clearly and obviously wrong. Nine non-functional refrigerators in a room would be even uglier than the Magico sub. Also I expect that if one dropped the wood JTRs on the thick aluminum Magico from some height, the metal subs may be dented but the wood subs would be demolished.
Now that brings me to my other favourite point of diminishing returns.
Loudspeakers and subwoofers.
Why try to press and underequipped loudspeaker to do bass of any kind? If you have a clean enough subwoofer driver ( not as common as you may like to think ) You can easily crossover a subwoofer with an 8th order high pass and lowpass at 160 hertz. The gain in this endeavour? much more impact in the bass. Much cleaner midrange and lower midrange and a much happier wide range amplifier. And no if your sub is not of the one note thuddite camp, you will not be able to localize where the subwoofer is. I have done this for well over a decade and if I don't tell people they don't know. But the caveat is that you need a very clean subwoofer. That means low distortion and very low harmonics.
