You should see the price of those 55W 24V truck headlight bulbs !
All bets are off for pro-gear 
A comparable naked projector bulb would regulate fine if you could find
a brand that has solderable leads. They're usually an alloy that
doesn't conduct at low voltages and resists soldering because of a
durable oxide layer.
Sylvania actually make a specialist range of bulbs for this purpose as
used by JBL
and Eminence in their crossovers to name a couple I know of

See HPCCR.

Wharfedale use these too. Some have a Red Dot and are stocked as such. It
would seem these are chosen as part of the design. They don't just fit some
truck bulb they bought at Halfords.
Hence my prior suggestion of going to the manufacturer to get the bulb
intended for the application.
