noobslayer77 Posted November 10, 2016 Report Share Posted November 10, 2016 Fi recommends 3-5 cubes. I was thinking 4.5 with a 6" aeroport. Never run the subs before. Going on a skar 3500 at 1 ohm.

Triticum Agricolam Posted November 10, 2016 Report Share Posted November 10, 2016 The tuning frequency is going affect how much port area you need as well. I'm going to assume you will tune somewhere around 32 Hz. A single 6" aeroport is less than 30 sq in of port area. That's not much at all for the size of box you are thinking about and the amount of power you are going to be running. Port compression sucks. Even two 6" ports will be quite a bit on the low side in my opinion. For comparison purposes, Sundown recommend 68 sq in for a Zv5-15", and that's assuming RMS power of 2,000 watts. In your situation I'd like to see AT LEAST 75 sq in of port area, 90 sq in would be better, especially if it's a slot port. A 10" aeroport would be good too. In either case the port is going to need to be fairly long to get tuning where you want, which can make things difficult, but that's the reality of the situation.

My thoughts exactly, though I suspect an 8" flared round port would not sacrifice too much. Link to comment Share on other sites More sharing options...

They are usually worth the effort though. You have plenty of room for a well sized slot port.

Kyblack76 Posted November 10, 2016 Report Share Posted November 10, 2016 I ran a bit large volume wise on mine. But also ran low on my port area. Loved how it played. I would run 4-4.5 cubes, around 55-60" of port. Tuned around 32, not much need to go lower, they will play down, trust me, then, let em eat. You can do more vent if you want. Edit - I wouldn't do 90" nope , most I'd do is around 75. But that's me. And I like the 3500 board, if your wired at .5. Or .7 nominal.
