ok so today i was showing my new cabinet to my band and noticed something about the speakers, the top 2 are black shadow MC-90 speakers, but the bottom 2 speakers are labeled vintage black shadow and are rated at 50w each. they are also 8ohms but are labeled vs-12 where the other speakers are labeled mc-90.

so whats up with these vintage black shadows? are they mesas take on the vintage 30 speaker? and just checking, if 2 speakers are 50w and 2 are 90w, the cabinet is rated for 200w?

also the way these speaker are arranged is that the normal black shadows are on top while the "vintage" ones are ion the bottom. should i x pattern these speakers or leave as is?
