A question. Most cabs have several speakers of the same size. Like: 2x10. Or 4x10. Or 2x12. But some cabs have speakers of different sizes. Like: 6"+12". Or: 10"+15". Or even 6+8+10+15. My HiFi speakers at home are of this type as well, they have a woofer, a mid-speaker and a tweeter. Theoretically, I would say that cabs with different speakers would be more 'broad band' and 'same size speakers cabs' would be more 'narrow band', and maybe more cutting. Is this true? What are the advantages/disadvantages of different speaker sizes in one cab? And why don't we see more 'mixed' cabs (the schroeder 12+10 is one of the few. Glockenklang has a nice 10+15 as well). Thanks for all answers, guesses, remarks etc. !
