There is a new subwoofer line available at parts-express, called the MX "Max-X High Excursion DVC Subwoofer". It is available in a 10, 12, and 15 inch models and costs less than the equivalent Ultimax. Excursion is listed - somewhat confusingly - both as a Klippel verified 70% BL rating (called 'XBL', no relation to XBL2 motors) and a mathematical (lower) Xmax. I think it came out on April 15, 2020, though I never saw any marketing for it.
Notes from AVSForum:
"If this is indeed them finally releasing the HE series they teased a few years ago then there isn’t an 18. It was planned but never materialized."
"I'd say it's more about trade-offs than one being better than the other. For sealed, I'd lean towards the UM and for ported towards the MX."
Marketing Blurb for the 10:
The Max-X MX10-22 10" dual voice coil high excursion subwoofer from Dayton Audio is built for incredible low frequency extension and high SPL. This affordable driver combines durability, efficiency, and maximum displacement into a great looking speaker that will deliver the deepest bass with power and authority. Optimized for use in compact enclosures this driver is ideal for home subwoofer designs and high impact car audio systems.
Key Features

What are the compromise of going for a driver that fits in a smaller box? Whats "wrong" with the HO or HF version?
Thank you GM. I am expanding on my multiple sub system and was beginning to wonder what might make it better. Using a Dayton 15HF rather than my current Scanspeak discovery 12" or XXLS 830952 - would maybe give me deeper bass in around 100 liters... but I have to think about proper integration as well.
