Voice coils in parallel: Volume 36,9 liter/1,30 cuft, Port: 3" diameter with length 25 cm/9,84". F3= 30 Hz

Voice coils in series. Volume 40,4 liter/1,43 cuft, Port: 4" diameter with length 17 cm/6,7". F3= 50 Hz

From the DLS website

I don't think you're going to find anyone on here that has actually run them. If they're anything like the MW112D they don't like loads of port area.

Thanks.

I already had that info and just thought that there could be anyone here that can calculate on SPL boxes.

I have one suggestion thats looks like this:

40liter box, 180cm2 slotport thats 53cm long.

WAY too much port area. I would run closer to 60L with 2 100mm aeroports. Then cut the ports until it sounds good to you.
