I did that at some point with my (then) Avant 1st gen….just for fun.

But switched back to using my surrounds again.

People should not be shy of trying out things - no harm done, you can always return to what you had before.

P.S.
The BST as the ‘motor’ has made experimenting much easier.

For instance I have ‘the triangle’ as one of my listening positions…..mostly for demonstrating for friends how well that works.

Absolutely true about BST making tryouts easier.

the one thing I dislike as a designer is the fact NoTo put the mic port behind the curtain/wooden cover. The plastic pins break easily as I experienced with a BL17. That fixing hasn’t changed for newer speakers.

the shadow joint between the two sheets of aluminium would have hidden that mic port perfectly at the bottom.
I find myself being afraid of unmounting the front too often when beta testing and when repositioning or experimenting with alternative speaker layouts in the room.

another idea is we would be able to make a backup of the listening positions and room measurements. Now when updating it sometimes loses the calibration. Loading a backup file would at least take the hassle out of reinstalling and calibrating a setup with many speakers.
?

will have to redo the process next week when the BL8’s arrive…

want to test some different layouts

Question about this suggestion:

Set the external loudspeakers to Left- and Right-Front
Set the centre output on the television to Centre Front
Set the Left and Right internal outputs of the television to Left- and Right-Surround

when calibrating the theatre with multiple speakers some speaker roles (and I believe woofers) are left out. Does the theatre still use these woofers for other channels or not?

The side firing are left out most.

I could imagine the sides supporting a surround or even back speaker roll and keep the BL28 behind the sofa as surrounds for most effect/usage.

With the added BL8’s should the L and R woofer group of 3 be left as L/R  channels with added 8’s further out in line with BST or all configured as centre?

BST gives a master control and balanced calibration but the assignment ment of channels is a bit unclear when having built in and external speakers competing the same position they are built for

Thanks for the reply, I think I understand that the BST will not automatically assign double speaker roles to two different drivers. But this can be done manually if desired

Would the BST calculate the timing of the back speaker role assigned to the side firing speakers instead of putting physical satellites (BL8 or BL28 or BL17) in the back?

To clarify: You calibrate a position and the mic measures the room. Then after you assign the back channel (not surround) to the side firing to have it reflect from side walls. Will this result in a timed output to reach the position and experience a virtual back sound?

 

As for the suggestion it's quite simple: relocating the mic port to the base of the BST to have free access not to break the delicate knobs on the back of the cover that you push into the rubber fittings in the soundbar itself.

Thank you again, made me understand the room sense a bit better now.

The initial measurement that is 'pushed' to make a listening position might be confusing because the flow of the process is somewhat different. It would make (more) sense to have the BST play a beep and the user defines the speaker position on the app(since BST can't really tell if sound is coming from above or more Left Front rather than Lift Side for instance). Then next step you would do the sweep for the actual speaker role rather then redoing it.

I will recalibrate to make sure, and to have the test of calibrating with the new beta.

When al speakers are positioned and angled properly it should only require 2 calibration positions, a sweet spot(perfect middle) and an off center lounge corner to watch TV.

Does it make a difference if you calibrate with narrow or wide beam width? I would expect the sound being reflected different with or without the sideways mounted drivers being used, or does the BL28 not use the side mounted drivers during calibration (either direct or through BST)?

This feels like a rabbit hole, keep digging deeper the more you know ;D

Indeed, I would just read the Technical Sound Guide, it helps give a better understanding.

With respect to wide / narrow mode - the TSG does mention that for 50/90s, put the speaker in the preferred preset (part of which is wide / narrow) before doing the mic based setup with the Theatre.

"you should ensure that the Beolab 50s or Beolab 90s are in the appropriate Preset before running the automatic setup measurement on the Theatre."

Whether that applies to the BL28s, I dont know.
