[QUOTE="Trixter, post: 2795978, member: 542668"] if you double box volume, you double port AREA....not volume. if you simply added volume by adding length, it would just change the tuning and still not allow proper air flow. double the area and then add the length (volume) according to the desired tuning freq.
