Nope. It sure ain't.
You know, I think I've gotten more out of carefully rereading and cross-referencing a few pages of the Parts Express catalog than I've gotten out of several hours darn near sweating over the Loudspeaker "Cookbook."
Let's see if I have things more or less right - A crossover, say a Linkwitz dealie that'll do a 12, will have two sets of inductors ("L" Why "L"?) and caps (at least I hope that "C" means cap...), and the different values will allow different frequencies to pass (or not pass) through... I think that folks also use resistors to lower the volume to select speakers, so that one may use a more efficient tweeter with a less efficient woofer? Or am I mistooken?
Looking at the formulas that the guy has in there to determine the settings for a two-way 4th order, I'm wondering about more than a few things - Such as "What's a Henry?" "What's a Farad?" "Why doesn't the speaker catalog have this information, so I'll at least know which speakers to buy?"
Hey, I can do the math - but it'd help to have at least some of the numbers to plug into the equations...
Now... I'm wondering... Say I'm gonna go with a 2nd order LR crossover that's prefabbed (the blue one that PE sells) that rolls at 2,000 or 2,500 hz, why won't this work with the 6.5 Dayton woofer and 1.8" Dayton tweeter? Seems to me that, according to the table in the VD book, that 2,000 hz would be low enough for the woofer, and also according to the book and the catalog, 2000 is high enough for the tweeter. So, PLEASE, what's wrong with this picture?
What would be "wrong" with the speaker, assuming I have things correctly mounted in a properly sized box? Not asking this just for grins - I'd like to know how I'd be screwing up, without first screwing up, you know? Would the speaker sound like I accidentally sealed a cat inside, what?
And I'm _still_ wondering (the dang thing doesn't have an index... or at least I haven't found it yet...) how to determine box size if you're doing something like using two woofs, or a woof and an unsealed mid/midwoof...
