Not really, the crossover can fix the differences
2.) When selecting a midbass & tweeter combo, I read somewhere that the tweeter should pick up 1-2 octaves above the Fs (resonant frequency?) of the midbass? Is this true? If not, what is the guideline in selection? Is it smarter to stick with the same brand between midbass/woofer and tweeter or does it not matter? Also, if using an aluminum cone midbass should a metal dome tweeter be used for continuity or can textile domes be mixed and matched with aluminum midbass/woofers and vice-versa?
You want each speaker to be able to operate in it's "sweet spot". As for brand mixing, it doesn't matter as long as the crossover is good
3.) How important is building your own crossover? Would I be able to get away with buying a pre-built xover from PartsExpress or some other retailer without sacrificing too much in sound quality as long as it mated well with the drivers I've chosen?
This is __BY FAR__ the most important aspect of DIY speakers. If you don't have an INTIMATE knowledge of crossover design and the proper toolset to take measurements and tweak designs, don't even bother because you will end up with very very subpar results
4.) From messing around with WinISD, it seems to be only for subwoofer cabinet construction, is there anything similar (that's $free$) for designing bookshelf or tower speakers?
Not that I know of. I don't mess with crossover design much, so I just stick with established designs that others have done.
Thanks guys. I have The Loudspeaker Design Cookbook coming, but I just can't wait! And searching the web yields too many deadends, not to mention me getting distracted by other information, so I figured I'd ask here.
