Question about DIYing my crossover

[piro]

Hi
I'm building my very own 3-way speakers (yay for me), and in the process of searching the web I found a nice little crossover calc.
here
The thing is, that a bandpass filter is shown, which means it's a 3-way crossover, but in the calculators input I'm requested to enter only one crossover point - between the woofer and the tweeter, no midrange involved.


what am I to do?
If anyone knows how to use this or could provide me with an alternative one, i will be grateful.

btw, any tips as for DIYing my speakers will be welcomed

All the calcs you need are there. Take a look at the schematic.

What do you mean?
In the site I gave?


your site also gives a 2-way crossover.
my question is what crossover point should I enter in order to get the correct values for the components.

according to my site, so it seems, fif I enter one crossing point the bandpass will not allow trough any freq' higher
or lower from that freq' which, I'm afraid, means none.
(but that one specific frequency)

Lusso5 is right. There is enough there to design a 3 way crossover - you just have to think a little. Anyway, textbook crossovers don't do the job in the best manner possible.

Oh well I guess I'll break it down

A midrange is just simply a speaker with a low pass and a highpass inline. So you just calculate where you want the low pass...like a tweeter, then calculate where you want the low pass...like a woofer. The mix em together....order shouldn't matter (IE, the highpass will reject lows, then move to the low pass to filter out uneeded highs).

guess it didn't work in last post....

Tip for a DIY 3 way: pick drivers with the smoothest widest response.
If you can use a high sensivity woofer, this will require less attenuation on the mid/hf.
I would suggest Seas ca21rex/mp14rcy/25tffc.

Hi again.
Well, due to rhe overwelming negative replys I got about making a three-way, I'm seriosly considering turning to a more simple 2-way.
Incase I do keep the original idea what do you think of these three as a combination?

Tweeter - Vifa DX25TG05-04, 1" .
Mid - Vifa P13WH-00-08 or seas MP14RCY both 5".
Woofer - Madisounds "home brand" swan 305, 12"

or incase of a 2-way:

Tweeter - Vifa DX25TG05-04, 1"
Mid-bass Audax HM170C0

thanks.
