With respect to the Magnaplanars, you would need a pair of speakers the size of a football field to yield excellent bass. Being made with mylar sheets, plus electrostatic technology, bass reproduction was not their shining feature. This is why they worked well for classical music (bass heavy pieces notwithstanding) or for those who were not intersted in the sonic regions we like to play in. Martin Logan, SoundLabs and others more recently made hybrids, using electrostatics for mid and treble regions which yielded excellent transparency, but very narrow soundstaging, with subwoofers to bring out the bass (problem here is that the subwoofers were not as fast as the panels, thus one may not hear a totally interated sound bass to treble). Klipsch speakers were, and still are much better at bass reproduction, and extremely efficient, which means you do not need massive power amplifiers to obtain a loud clean wall of sound. Back in the day, Altec Lansing, and JBL made efficient loudspeakers with terrific bass. Both Altec and JBL, as well as Electro Voice, made outstanding woofers (some still make them currently) which helps us bass people!
Ah, the curse of being a home audiophile, and an addict of Alembics! So the kids have to starve, so what, big deal (LOL for those too literal to understand sarcasm).
