Glad to see these, options are few for high excursion passive radiators.
Are these *based* on the HS-24 soft parts, or are they smaller diameter *for* use with the HS-24?
Looks like there's no provision to change the mass from the front? I'm assuming there's an easy way to at least change the mass from the rear?
