You may like the polypropylene driver retro FM radio 80’s sound. Mission first started the great trend in this tyoe woofer. Polypropylene can be a bit nasal because of low resonance ringing (rigid drivers) but Spendor and others found ways to control that with the way the surround and voice coil are mounted.
Great to hear you found what works for you. I have an old pair of Energy Pro 22 - my first serious speaker - love that sound (Energy stitched the surround to the polypropylene cone and it worked well to limit resonance- although I can hear it compared to say ATC)
