2 way + subwoofer (crossover and 2 way box design)
Hello, I am planning to make a pair of 2-way speakers for indoor use (mainly as home theater and occasionally for music). The 12" subwoofer that I currently have should reproduce the lower frequencies below main speakers. Whole setup would look like this:
*24 dB/Octave 3-Way Linkwitz-Riley Electronic Crossover from ESP;
(3100 Hz crossover from mid to high; ??? Hz crossover from low (subwoofer) to mid)
*Eight Band Sub-Woofer Graphic Equaliser from ESP;
*Active Sub-Woofer and Controller from ESP;
(for 47l sealed 200W subwoofer with adjustable 50 - 150 Hz 2nd order Butterworth crossover)
I have two questions after running a few simulations on WinISD:
What crossover frequency would be a better choice, given that the excursion of mid woofer is over the limit at 200 Hz with 70 W applied? (Speaker parameters: Prms = 100 W, XMAX = 1 mm, linear XLIM = 2.5 mm)
If I set the XO to 123 Hz, XMAX peaks at 2 mm;
If I set the XO to 150 Hz, XMAX peaks at 1.5 mm;
After enabling the XO in WinISD there seems to be almost no difference between box sizing. Next photos should illustrate what I mean:
So does this mean that I can ignore the XO and simulate the box with XO disabled OR there is no difference what size box to choose?
I will be thankful for everybody with any ideas.
