Behringer V-Tone GM108 15W Modeling Guitar Combo Amp

I have purchased the Amp Combo above in the subject line.  I would like to know if this amp will accomodate a 10 or 12 inch speaker to replace the 8 inch that it is going to arrive with.

This is all new territory for me, but I have a 10" 35 watt to use in this 15 watt combo.

Thanks for your help
