BW Nautilus 805, better to have them ported or sealed

Hi, i had to ask people, who've heard the Nautilus 805 speakers. I notice these speakers are ported. Thats that hole beneath the 6 1/2 kelvar midbase. Do people think its best for this speaker to be ported, or would it be best for it to be sealed. See i would think, if someone is going to use a Sub with the Nautilus 805, i would rather have them sealed and not ported. Someone told me, that BW did made them ported, to boast the bass in the Nautilus 805 speakers. That might be a good idea, if you were going to use the Nautilus 805s without a sub. But i prefer to get a natural sound and not to boast any bass.

Good question.
B&W has the largest research facility of ANY speaker company in the world. I wouldn't fool with the basics of their design unless you really have a lot of knowledge of design.
That said, what you want to do can easily be tested. after you get the subwoofer of your choice, set it up and see what YOU like best, with the port open or closed. I would be willing to bet that you will end up leaving the speaker as B&W designed...open.

Before I would make any major change, I would want to know that the person or persons designing the change, really know what they are doing, and hopefully be able to hear the change before making any big alterations on my equipment. And, I did do just that with the B&W800's. Dan D'Agostino of Krell designed an active crossover with bass alignment and designed some minor alterations with the crossovers and wiring for this speaker. I followed his advice and ended up with the single largest improvement I ever made to my system, bar none.
Enjoy,
Richard
