Magicos are chesty

My guess is you are hearing the sound of the polypropylene plastic bucket that houses the midrange.

Polypropylene cones always had a chesty sound - as if the vocalist had a bit of a cold. It was apparent in many of those designs of the 80’s - BBC speakers and Mission 770 etc. Very popular back then as you punch the cone out of a sheet of polypropylene very cheaply.

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 or cabinet for a speaker cone.

You can observe this effect with any plastic bucket when you start filling it with water - the frequency is lower mid range.

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.
