I'm mot sure that these use a SMPS. They specifically specify 110-230V AC, 50-60Hz which makes me think there may be a mains transformer in there, possibly producing more than one voltage. Would the manufacturers clarify this, or even tell you if there's a DC supply option that could be retrofitted?
I'm not sure about the consumption figure. They say 208mA but that's over 20W at 110V, not 15W.
I'd use a 30VA reversed transformer if I was doing an inverter, I think, That's 74 dia x 31mm.
There is a problem in finding a suitable power amp to run from 6V though. The lowest I've found so fat is 8V. That's a 30W bridged output.
