Have a buddy that has 2 Sundown Nsv2 18s and is wanting to do a 4th order bpillar wall and is trying to get info on the ratio he should go. He will have 10k or so on tap.

How many cubes sealed and how many ported would you recommend?

Thanks

6 cubes sealed and 15 cubes ported. Before loading wall goes on install woofers and run a sweap. Tuned ported section to the res freq of sealed side. Good starting area for port is half on cone area and shrink or make bigger whatever gets ya louder.

Are the v2's even good for 4th orders I know the v3 is but I thought the v2 was better suited for ported or 6th order.
