Please note I am NOT knocking Class-D speakers or products but I came across this and wondered about their ethics? I've emailed Garry at Class-D for a comment but had no reply. Your thoughts please. :)
From Class-D:
‘Heavy duty 18" cast aluminium frame for increased rigidity
Copper voice coil capable of dissipating tremendous heat build up when driven in concert conditions
Huge copper area and breathing arrangement of the voice coil ensures superior power compression performance
Double suspension maintains pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours of life on the road
Designed to provide superlative high power bass and sub bass, suitable for all systems demanding the best possible low frequency response. A popular choice for horn loaded subwoofers.
Ideal for three-way direct radiating systems where the powerful bass comes into its own.’

'Heavy duty 18" cast aluminium frame with extra wide flange for increased rigidity
5” copper voice coil capable of dissipating tremendous heat build up when driven in concert conditions 
Huge copper area and breathing arrangement of the voice coil ensures superior power compression performance
Double suspension maintains pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours of life on the road 
Designed to provide superlative high power bass and sub bass, suitable for all systems demanding the best possible low frequency response. A popular choice for horn loaded subwoofers when the PD.186’s full low end can deliver extremely high SPLs.
Ideal for three-way direct radiating systems where the powerful bass comes into its own.'
