Some B&W speakers with ports come with foam plugs you can insert in the port to adjust the bass output. I have a pair of CDM-1 and P5 and they both came with foam plugs for the ports. The foam is not a seal, just a reduction of the air flow.
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.
