Default Ekta Grande cabinet size?


If I were to build the Ekta Grandes: Ekta GrandeScanSpeak 18W/ with 38 litre sealed cabinets, would Troels' original crossover still work?

I have noticed that Zaph offers both options in his 2.5 way ZRT: Zaph|Audio - ZRT - Revelator Tower (38 liter sealed, or 65 liter vented) without any XO changes. Both designs use the same drivers.

should do, as long as you don't change cabinet width; but there'd be no point, using 2 drivers requires that volume to get the bass response, you might as well built the ekta if you can't go over 35L: 3
Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency
