I'm planning a sealed box that will hold 2 RSDC10.4 subs.

The recommended size PG gives is .382 cu.ft which seems awfully small.

Does anyone know if what they recommend is best or is it better to go bigger?

The port I'm using is 3" diameter and 7.25" in length. That should give me a tuning of 33hz from what I understand. I read 33hz was a good tuning point for good sql but I don't know if thats true. I figure it's easy to make it longer or shorter if I need to. Oh yah I forgot to say the rsd ...

I am thinking about getting the rsd10d but have a couple questions about it. 1. Will it be ok to use with an infinity 611a monoblock amp rated at 650 watt rms? I want to be able to use the full 650 watts if I can but the rsd says it's only rated up to 500 watts. 2. Is an enclosure measuring 2.0 cu/f...
