I believe the Ecomodder's speaker would be the Infinity Kappa, with a 95db sensitivity. Compared with some speakers with lower sensitivity, they can produce as much as 10x the volume with the same energy, or the same volume with 1/10 the energy.
I've used Polk MM series a lot. Neo magnets means they're much lighter than any comparable speaker, they also have a composite cage and are marine rated. 93db sensitivity.

But of course it's not that simple, most 'high end' speakers are designed to be used with a subwoofer so they tend to produce less bass than the OE paper cones. If you need to add a small passive sub you'll eat up any weight or electrical efficiency gains.

OE paper cones always amaze me with how good they sound considering how crappy they are.
