it's actually opposite, 2 passive and 1 active...

I Found the BL10 with acustic lens technology more appealing than BL 7.2.

Also I heard that the sound of BL7.2 is not so good

Aha! So the info here should be corrected, then? I used that for reference.

That's right 🤒 And visualy, the rectangle/triangle combination is very nice 🙂

The BL 7-2 is a stunning stand alone speaker, but for 5.1 set ups doesn't work very well

Do you know the volume of air the BL2 shifts per impulse?

 

yes that info should be corrected.

i have no clue off the volume of air the BL2 shifts per impulse, but I'm pretty sure it is much less than the beolab 5 shifts 🙂

Actually I found that the 2 (BL2 and BL5) work together quite fine. When BL2 reaches its maximum, BL5 steps in. The sound in action movies is massive. Much better than in any cinema. Luckily my neighbors are away very often :-)

Marc, I'm pretty certain you've been cheated of a very nice experience. Due to how a B&O system is set up, your BL5s aren't getting any LFE and are also not using the subwoofer much when you watch movies ...

Unless there's been some trickery in setup, all the LFE (Low Frequency Effects) and subwoofer info, is going to the BL2. It's kind of weird not to be taking advantage of 2x38cm subwoofers.

Which is why I was fortright enough to write that your dealer didn't have a clue if he thought a BL2 would be of use together with BL5s. For movies, you now have a 2x1500W BL5 setup, not 2x2500W. And that's why your dealer thinks you need the BL2s - no wonder, since the BL5s aren't doing anything at all with the information that action movies are filled with.

As Odd pointed out above, you have ONE active diaphragm on the BL2, with a 25cm diameter, that's 37% of the surface that your BL5's subwoofers want to work with, if given a chance, to set air in motion in your room.

You have a BeoSystem 3. Disconnect the BL2, and set the system up to send the subwoofer info to the BL5s - it might be a revelation.

Congratulations on a beautiful set-up Marc.

Which cuts both ways, JB - but as Marc says the BL2 kicks in first, and then the BL5s join in, it seems very likely that the LFE is going to the BL2 only.

There would be BL2s galore in the Struer cinema if that dealer is right. 🙂

Let me again point out that I feel Marc's installation is stunning and speaks of excellent taste - yet I'm curious to know if those BL5s are being allowed to do their best.
