Skullz Posted April 20, 2010 Report Share Posted April 20, 2010 What i was able to find out on roe was more than 2.0 and more towards the max on port area and tuned to 35hz/38hz, so your prolly looking for 5.5 net with a larger port area and tuned to 35/38.

Skullz Posted April 20, 2010 Report Share Posted April 20, 2010 Yeah that is a shared chamber and around 82"/85" port area for the 2. If you don't have torres box calculator might wanna get it and play with it. http://www.stevemeadedesigns.com/board/topic/38791-torres-exposport-box-tuning-calculator-updated-310/ Quote 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

Skullz Posted April 20, 2010 Report Share Posted April 20, 2010 Longer the port length the lower frequency. Quote 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

I've found alot of port area (16-20sqinches) and enclosures on the larger side of the recommended to work very well for me.
