Plugging the bass conduit
Hi everybody,
New on the forum. I own a pair of 802D3. I have an excessive bass response in my room (+15db at 30Hz), which makes it quite inaudible. Solution would be to plug the bass conduit (doing so with textile improves significantly the situation). Does anybody know whether B&W has a mousse for that (they refer to it in the owner's manual but I could not find it in the packaging I received). Thanks in advance. |
Hi,
You must be referring to Foam Plugs. I don't think 800/802/803 D3's have foam plugs; it's not even listed in BW Group North America Support Parts List. I think this is a typo on the French Operating Manual referring to these (as tampons de mousse). Not sure if the 800->803 are designed to have Foam Plugs. You may need to place the speakers away from walls further, if that is possible in your setup. 804's/805's have Foam Plugs. That would compromise the full capabilities/potentials of the speakers. Best not to use them if you could place the speakers properly as optimally recommended. Thanks. Ron |
And/or you could get an amp/processor with bass management to handle the bass peaks in your room. Won't help much with potential cancellations though, but you'd be able to take that +15db hump you are referring to.

Thanks for translating mousse to foam ;) . I checked and there is no reference of foam plugs in the English part of the manual. So you must be right. Thanks for answering. |

Thanks for answering. This is exactly how I could check the exact level and frequency of this anomaly in my room. I am using a Trinnov Amethyst, and the diagram, which I can not display here (not sure how to post pictures ?) clearly shows a peak at 30Hz; unfortunately +15db is above correction capacity. If I am inserting foam sheets or textiles under the the bass conduit, I can decrease the peak from +15db down to +10db where the processor can help. Just wanted to know if there was any appropriate foam plug. I didn't precise that the distance from walls are already 1.5m (5 feet) so much more than minimum requirement from B&W. Thanks again, Pierre |
Hi SwissBear,
Assuming the issue is at 30Hz, plugging the port might solve one problem, but mess up everything else. My suggestion would be a good parametric eq. Best Regards, Patrick B&W Group North America Quote:
