Dear Sir;
Bandwidth limiting, use a high pass filter. Don't send all the bass to the satellite speakers. Let the sub do the bottom octaves(20 to 40, 40 to 80hz.). Intermodulation distortion from the satellite bass/midrange driver will be reduced resulting in clearer sound especially at higher sound presure levels (SPL). Trying to guess the crossover point(blending) without measuring equipment is not good methodology. I used woofers in the past without a high pass filter and was never able to obtain good results. The sub I now use contains a high pass filter and I get good results from all my speakers(12 pairs) ported or not.
Hope this helps
Have a good one
