whats the difference between these sound wise?
Too broad a question, can you get more specific?
God Bless, Ray
The first needs one big hole in the cab, the second need two medium sized holes.
The surface area of two 12" speakers is greater than that of one 15". So they move more air = they produce more volume.
The following statements are questionable and a reason for hot debates since years
The sound of a 15" ist more deep an warm, (think of "blues"),
the sound of 12" more punchy (think of "rock"). Some people don't like 15" because of their latency. Some love them because of their full and warm sound.
One of these 15's will move substantially more air than two of these 12's. (more than 10 of them!)
My example linked above is extreme, but the point it is really depends on more than just speaker diameter.
The 1 vs 2 thing makes it hard to comapre. More speaker surface are = more air = more better! Subject to challenge as above.
Generally a 15" will be "rounder" sounding, while a 12" will be punchier.
The only difference that can be quantified is the dispersion angle. If the two 12s are mounted side by side, which they shouldn't be, they will have a narrower dispersion angle than the 15. If mounted vertically, as they should be, they'll have a wider dispersion angle than the 15. Other than dispersion you cannot make any accurate comparisons without knowing the exact driver parameters and cabinet particulars.
Rounder and punchier is almost always determined by cabinet tuning and not driver size.
And if not cabinet tuning, it's more likely to be specific specs of the driver (e.g. that determine whether there is a big low mid hump or upper mid hump or whatever) than the size of the driver.
