Something in the range of 90x60x 80 deep would be ideal :)

Could probably cross higher, here is the rb212 measurement (unfiltered):




Looks okay upto 450hz to me.

I found them best with a 24dB L/R lowpass a about 370Hz, any higher and the resonance started to creep in, i used to highpass the 4595s a bit higher though but they crossed over ok due to the rising response of the RB212 in that range, so the acoustic crossover point was a little higher than 370Hz.
