ported vs sealed which do you preffer?

[gonzo]

0.5 cu.ft. is the recommended optimum volume that your enclosure will yield the best bass reproduction. If you increase the volume, the resonance frequency will be lowered with lesser power. You can still use 1.0 cu.ft provided that you have to add stuff (fixed wooden blocks) in your enclosure to get a net of 0.5 cu.ft.

Thanks
