Magicos are chesty

erik, I'm sorry to say I don't remember which series the 3 or 4 pairs of Magico's I've heard were. They were at audio shows and in a listening party in a home space and all were listened to in the last 3-5 years. As always YMMV, if you like the ones you are considering and have chance for an in-home trial with your gear and like them, buy them. Your ears and taste are all that matters. If you keep wanting to play LP after LP deep into the night, you have a winner!!!! 

I really loved a system I heard last year. YG Acoustics Carmel 2s - Rega P3 w/Elys - Rega Maia 3 power amp - Croft Acoustics Micro 25 preamp - Audio Analysis lowest level cables. All modest, low cost gear except for the YG's....super clean, detailed system, played classical, funk, jazz, acoustic folk, electronic and rock n roll all equally well IMO....

The problem is that polypropylene is non-fibrous and tends to store rather than dissipate acoustic energy so it vibrates characteristically - not a good material either for a speaker cone

Wrong. It and paper are the best materials for a speaker cone. Go listen to the Stirling Broadcast LS3/6 and then claim plastic is a poor driver material. They can likely embarrass whatever speakers you're listening with.

Audiophiles and Men like chesty speakers and ladies . Its the American way !

I love the sound of polypropylene cones. My first higher end speaker was Energy Pro 22 with a poly mid-woofer woven onto a rubber surround.

That said, my experience is that polypropylene cones almost always sound more rolled off in the 1 to 3 KHz range and more lively around 200 to 300 Hz (a more “chesty” sound). This gives them a “warm” characteristic versus pulp/paper which has a more lively sound. Both can sound good.

In the case of Magico, from internal pictures it seems they use a large internal washbasin size plastic cabinet around the midrange. Ostensibly to limit the backwave from the woofer influencing the mid range. I suspect this plastic tub could add a warm chesty coloration - vinyl shower or vinyl bath tub will give vocals that kind coloration should you be inclined to sing in the bathroom.
