Question 1What is the frequency range of my BeoLab 19 subwoofer?
Question 2If I add a pair of BeoLab 28 to my system will the bass management redirection logic table send the bass signal to a BeoLab 28 or to the BeoLab 19 subwoofer?
Question 3Please may you publish an updated bass management redirection logic table which includes BeoLab 17, 18, 19, 20, 28, 50 & 90 as more people are using an Eclipse, Harmony, or Contour with home speakers in a movie format.
Answer 1From searching the forum, I found a Geoff Martin answer “For the BL19 it’s 21 Hz – 900 Hz”. Has anyone tested this?
Answer 2The specs for the BeoLab 28 are “27 - 23,000 Hz”, so bass should still go to the BeoLab 19 subwoofer, but my dealer says this is not the case in the showroom.
Answer 3Is there an updated table listing the BeoLab 28?
Present: Eclipse 55” Gen 2 with motorised wall bracket. Plus 2 x pairs of BeoLab 17 + 1 x BeoLab 19 using WiSA to the soundcenter.
Also LG 55” C9 + BeoSound Stage in another room. And 2 x A1 Gen1 as PC speakers.
Past: Eclipse 55 Gen 1 and before that an Avant 55” MK1.
Hi,
Customer Care can't answer these questions because I haven't provided the answers for them... So, you can blame me personally for this.
Question 1: There's no real answer to this question for the reason I explained in this web post about how B&O defines Frequency Range.
Question 2: I can't answer this until I get back to work in January. I need to check on the measured capabilities of the speakers to be able to answer it. If you can't wait until January, you could lie to your television and add a pair of BL28s in the Speaker Connections menu on an unused Power Link connector. Then make a new Speaker Group with the 28s and a 19. Then go into the Bass Management menus to find out what it decided.
Question 3: I'll spend some time making the table - but since I have to do this manually, it won't happen quickly - sorry. Note, however, that it won't apply to Contour, since it don't have any outputs for external loudspeakers.
Cheers

Thank you, & apologies Geoff.
I appreciate you replying personally. You are a great ambassador for B&O and the oracle when it comes to anything technical we may dream of asking.
Sorry for the thread title, I have asked a series of questions in the past few weeks via the Customer Care form, each time with the refer to your dealer response… I didn’t realise they were being investigated.
I will wait patiently as I can imagine you are extremely busy. Also my asks are quite specific, and I now understand also manual to answer, so not something you can complete quickly.
The table is such a reference so I am sure a 2022 update will be something many will want to read when published.
Wishing you a wonderful festive time, filled with magical moments to treasure well past decorations being taken down.
Simon
Geoff, thank you; you are a superstar for turning this round so quickly!
I found the updated Technical Sound Guide dated 05 January 2022 with the complete bass management filtering table, now including BeoLab 28.

I hope others will find this as interesting a read as I do.
Some questions are easier to answer than others, if you know who to ask for help... :-)
Note that I cleaned up a couple of errors here and there in the document while I was in there. Nothing life-altering, though... Just a typo or three.
