+1 to Bongo. Putting it more strongly, not only would it not do the same thing, but it would do a bad thing... suck out a lot of key bass frequencies for a big tone, but removing none of the subsonics.
However, again per Bongo's earlier post, this can be a trivial issue with a bass amp that has true hi passing set at a reasonable level, like the Genz stuff, or a disaster with an amp like the Mesa M6 or iAmp800, that seem to have no hi passing at all in their designs.
