Combination of 1st order and 2nd order crossover in 3 way box

I'm re-doing some old Sansui 3 way boxes.  Is it crazy to use a 2nd order crossover between the mids and highs but a 1st order between mids and lows.  I want to crossover at 375Hz and 3K Hz.  With the response of the mid and high drivers I think they would be better served with a steeper slope at the 3k mark.  Does anybody have a crossover designer to help me with this or am I going to cause more phasing problems that will negate the benefits?

Danny,


If you don't know the driver response, and acoustic offsets you can't possibly be talking about crossover typologies yet.


You really are a lot further than you think.  May I strongly suggest, try your hand with the simulated speaker I posted. See if you can make it work. If you start a thread on DIYaudio let me know and I'll jump in and discuss.


The simulated speaker is free, and you will learn a great deal quickly.


Best,

Erik

Erik,
    I have all of the driver specs but I haven't tested them in the box.  I was more asking the question about combining different order crossovers so that I can learn more about them and to learn people's thoughts on them.  I have since found a lot of info on it.  With just the driver spec's in mind I think it would be beneficial to protect the tweeter with a second order order high pass slope and the mid range driver would do well with a second order low pass slope given it's problems around 8k.  I plan on getting a good reading from them once they are in the box and going from there.  I will take a look at your simulated speaker.  I'm just in this for the fun of it.  Thanks
