I see, that you have a BV7-55 in your list.

Is that the audio processor, that you talk about?

In the BSys3/BV7-55 the bas management by far is not as advanced as in the BSys4 (e.g. the BV11-46).

As for the BV7-55 I have no idea how that is done - however, I assume that a BL5 will behave like a BL5, no matter where you put it and no matter what speaker role it has. In the BSys4 you have lots of options to do as you wish (even if you want to overrule the default settings there).

 

N.B. The more bas capable speakers you have, the better - this will in most cases be better in order to avoid room modes.

Stay tuned….my post/my answer went into moderation :-(

Depends what is driving them?

If it is a modern Beovision  with a full sound processor, the processor will distinguish what you have and how to deal with it. 

I imagine selecting BL5 as main/front L/R, the processor will be pre-programmed to sent the LFE.1 there.

similarly, it will also know not to send the LFE to the rear/sides

I want to drive the 4 bl5 with a bv 7 55. I cannot test it actually as I need to change the rear cables.

 

7.55 can send bass to all speakers, if you select bl5 for each channel it will already do this automatically. This doesn’t mean though that all speakers will get the same bass output as it depends on where the bass is placed on the mix of the dvd/cd etc. But if the dvd calls for full bass from the rear, you’ll get it from the rear. 😎

I would resort to my original comments. Select the correct  speakers for front and rear/side. The Beovision will do all the correct calcs. 

I would anticipate the fronts BL5s play the 2.1 with fUll LFE and  rear/sides will have diminished LFE per the preprogrammed sound profile

Why not let your ears decide?
