In Topic: Crown XLS1500 and Funktion-One

From the manual you posted : "Out of operating band low frequency protection is incorporated."

This means the low frequencies (bass!) are filtred outright by design in this model.  This is a top box.  Subwoofer is not only suggested, but mandatory.  You won't get any useful bass from a 10 inches speaker at party-level from any box!

If the Buttkicker needs a real subsonic filter, the XLS won't provide one.

I would say a large percentage of the heat go from the power devices to the heatsink by conduction.  I have seen designs where the heatsinks are below the power devices.  As long as the fans are working I'd say this is not much of a problem.  But I'm not a Crown engineer!  You should ask Crown.

I'm not a fan of holding to some ideology.  If the specs are good, class D will be just as good as class AB or A.  In my home theater, I use a mix of class AB (old Brystons and a Crown CTs 600) and class D (Crown K2 on my subs).

The old class D bad reputation comes from 20 years ago when it was not perfected yet and mostly used for doubtful car amps.  Now, even entry-level Crown XLS is as hifi as one needs, imho.

That's class D for you!  Efficiency goes from 45% to 85%+
