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?!!

It really depends a lot on your brand of subwoofer. If a REL ST series subwoofer is used for 2 channel music; then the high pass speaker connection is by far the best way to go.

There is no scientific explanation. This is how REL designed it to work, with the main speakers playing the normal full frequency range. They only recommend the pre-out connection for home theater applications because of the AC3/DTS bass signal.

Just an FYI...what Elevick describes is NOT how a REL is setup or how it works. It is parallel to the main speakers and is self powered. It takes nothing from the amp, but the signal; just like the sub getting the signal from a second pre-out.
