I'd try an X150.5 (2nd edition) first, plenty gain and current.
Saves cash, saves heat.

Désolé, it's a 1.5 Mega PDF, not able to convert to postable size images right now.

The X150.5 has roughly the same current capability as the 250.5, enough to do 105dB/m at any frequency, imo.
10W Class A operation for a 87dB/W/m efficient loudspeaker is sufficient for ~95dB/m continuous output.
Should be ample plenty for 40 square meters.
(speaking latest X150.5 model, has a much larger output stage)

The 4 Ohm spec seems somewhat optimistic, 87dB/W/m conservative, on the other hand.

A pair of XA100.5 would cost at least double! Even a pair of XA60.5 is much more than the X250.5...

I just suggested you try the combinations you want, to see with the local dealer, then choosing accordingly to what your budget can afford

Brds,

This is China... we don't have that kind of service! For many reasons I can tell you about... so I have to order and be sure. So it seems that my safest bet right now for the best value for money is the X250.5 no ?

If X150.5 is enough then XA30.5 would definitely be better don't you think?
