Could someone compare these 2

[hawkei67]

This is the box that I currently have in my 1999 Ford Taurus with a 220 watt pioneer kicking it. The box does have a divider board between the 2 drivers the same thickness as the rest of the box. This is the proper drivers in it also, got the model number off the magnets.

This is my box after running thru Bassbox Pro to improve it. What do you guys/gals think? Did I do it right or do I need to do some more number crunching. You will notice that I modeled it as a bandpass enclosure and added 2 vents at 2" in diameter and 4" long. I tried adding filling to both but not like the plots.

Let me know what you all think of the improved version. Also let me know of any suggestions you might have to better improve it using the current drivers and amp and car. Just playing around with my old box until I get started on my new single 10" driver vented cube box.
