I was wondering, in those surround satelites using 2" or 3" drivers and a small tweeter in a 5 inch by 3 inch by 6 inch box, I guess you really dont want to give them frequencies lower than 150hz.
that means you need 2 high pass crossovers (or one bandpass) , one for the mid and one for the highs.
for the highs. aint too bad, basicly just a cap will be fine, but for the mids......
If you do a highpass at 150hz for the mid, and wanna go polyprop caps, that would be a HUGE cap! 132 uF if the driver is 8 ohm.
If you go with electrolytic caps, the size would be reduced, but still, for a box that size, its quite big.
And if you do a band pass first order for the mid, its a 132uF and a
coil at 4khz for eg.. thats ever more parts..
and unless the walls are about 1 mm thick, I dont see how anyone would put all those parts in a casing that small.
Even worse, Ive seen systems like this one, where the subwoofer is using a 80hz lowpass..
Pls dont tell me those satelites can cover from highs to 80 hz....(whitout extreme xmax mids, wich will make distortion higher...)

I've been thinking in the same direction.
My problem is matching the rears to the fronts. In my case those are a pair of B&W 330i's

hum, I think 5.1 receivers should have a active highpass at every channel, like from 0hz to 100 hz that would be user defined and to be able to turn it off.
I'm ready to pay the 10$ more (if thats how much it'll cost them to make that per receiver)
that way the mid/bass in satelites would need only a small low pass and the tweeter would need a simple highpass
