Everyone should try both ways - with and without high-pass filter.
Every system and every room has its own tale.
I must say that it's (much) harder to setup/optimize subwoofers without high-pass filter, especially when low-pass filter frequency is not too low (and usually it shouldn't be too low) - the reasons are mentioned several times in this thread. But, in the end, it could worth the effort.
Since I'm not allowed to post links - just search for "Geddes Multiple Subwoofers".
