Line level or speaker level, scientific reasons? ?

Hi everyone, I've been hearing a lot on the forum that it is better to connect through line level from pre-amp to the sub. Now my connection right is using the speaker level connection and I think it sounds great. I am using bookshelf speakers and by using speaker level inputs I am able to remove the lower frequencies from the mains!

Wouldn't this be a huge benefit than running the full frequencies to the speaker? It frees up the amp to provide more clean power!

now what is better and why?!!

My less than 2 cents is, I've read several comments and reviews that say using the high level input from the amp makes for a more coherent sound. In other words, the sub amp borrows the characteristics of the main amp. Using a separate pre-out line to the sub is said to create bass that can be musically disjointed from the main speakers.

The input impedance on the REL’s(and other quality self-powered subs) is supposedly such that the additional high-level connections to the sub do not affect the main amp.
