Dear Geoff,
May you tell us why the ALT of the new BeoLab 8k is not integrated in the loudspeaker but placed on top ?
If you seat, the ALT seems to high for ears. In advance, thank you very much for your answer. Kind regards.

Question for Geoff Martin

I'm no Mr. Ear, but I'd take a wild guess that anything in close proximity of the lens will have a negative effect on its performance. You should see that on your BeoLab 12's. Lens is exposed, come to think of it every lens is exposed. Even the ones in cars raise up from dash...
I cannot see why an ALT cannot be put behind acoustically transparent material (wood slats are not such a material) but such devices are a styling feature which give an impression of modern technology and so hiding it would seem illogical. I agree the height is an issue - note the positioning of the tweeters in the Penta.
My B&O Icons:
Moulton Laboratories web page speaks of a 30 degree vertical dispersion of the sound. Also, the B and O web page describes ALT as reducing, not eliminating, floor and ceiling reflections. Clearly there is a wide vertical range of sound. Also, I don't recall any complaints here about the ALT on a Beolab 7-4 on a BV7 being too low, or the fact that a Beolab 9 is much lower than a Beolab 5.
the fact that a Beolab 9 is much lower than a Beolab 5.
Performance apart, the ALT on the 9's and 5's was designed to be there from the off and doesn't look like it's been plonked on the top as an afterthought!

Maybe it's not a real ALT, but rather a rain hat to protect the wood if the sprinkler systems in Shard was accidentally triggered by the film crew's lighting.
Makes you wonder whether there could be a separate ALT module that could be added to any speaker: a bit like the 2500 cube approach.

Razlaw, the height difference of the BL9 vs BL5 is 19,5cm.
The heigh of BL 5 is 97cm
Height of BL 9 is 77,5cm
Beolab 8003 height is roughly 142cm (Beolab 8002 is 132cm)
So suddenly you have a jump of not 19,5cm which is the difference between the 5's and 9's, but 64,5 cm between the BL9's and BL8003.
The BL9/BL5 have always seemed like the perfect heigh to be listening from a couch.
I can't help it. But the new BL8003 looks as if it was made in a rush. It looks horrible. Might sound OK, but I doubt it, since BL8000's biggest problem has always been midrange/bass not treble.
Geoff Martin says ..... Please dont ask questions , just buy it .
The (ALT) lens can be designed to aim at any chosen angle/direction so the height is quite irrelevant.
