[QUOTE="Moble Enclosurs, post: 7723711, member: 634917"] It is a decent response and is very accurate from my figures as well. There is an efficiency issue in this design based on the controlled response and excursion, but other than that, it is a decent conventional ported box and should perform quite well it seems. Be careful of the power levels below 35Hz due to the port characteristics, but it should not go over xmax, just may cause some noise from the port a bit is all.
