North Creek B&W 801 crossovers? Tried them?

Tab, thanks for the recommendation and warning about the bottom plates. I don't think I'd use the XOs if I couldn't have the bottom plates on while doing so, since I have the speakers mounted on Sound Anchor stands that fit over the plates.

I meant the bottom plates of the NC's. Mine was craked in half. They pack a lot of parts on a not-too-sturdy platform. I just remembered that I drilled the original BP plates to accept the NC versions with minimal fuss.

Do you have the Krell, Anodyne or Listen Up EQ filters?

Tab,
So you are recommending to remove the bottom plates of the NC XOs AND use spikes to improve their performance...therefore I'm picturing the XOs up on spikes with the bottom completely open, right?

I still don't understand your second sentence: "I drilled the original BP plates to accept the NC versions.." What are 'BP plates'? and the "NC versions" of what?

Thanks, and apologies if I'm being dense.

KEEP the plates on the Xovers(The electronics are attached to the covers).The bottom covers are about a 1/2" thick and don't seem appropriate for the load they support, so handle the Xovers with care(Each Xover are around 50lbs each). GET RID OF the bottom plates on the speakers. Unless you live outside, dust shouldn't be a problem. My Xovers had Binding Post(BP) plates that were supposed to be attached to the outside of the enclosure. I instead utilized the factory BP plate and enlarged the holes and drill an extra hole to accomodate the Xovers Binding Posts(My Xovers had wire leads for 5 BP's). Change the spikes that come with the Xovers to something more substantial such as the small Polycrystal/brass footers.
