Er, does anyone know what the hell Bugera speakers are?!?
At least other Behringer cabinets have Jensen, who actually produce quality speakers...i did a Google search for Bugera and found nothing, just lots and lots of links to those cabs you mentioned on various online shopping site :p
From what it looks like, those speakers would be no better than in my MG412 cabinet (

oh the shame of admitting it!!

)
