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.

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.

Razlaw: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!
Ban boring signatures!

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.
BeoNut since '75
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.
Too long to list....
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.
//Bo.A long list...
BO: The (ALT) lens can be designed to aim at any chosen angle/direction so the height is quite irrelevant.
read patent papers, its not irrelevant you can just narrow the angle for horizontal sound spread. but its 180 degree by default

You missed the point of my post. That point was simply that ALTs can be a different heights and still work fine.
Of course the 5s and 9s are both roughly the height of somebody sitting, although a 7-4 is clearly not at the same level at the listener. My 7-4 on my 7-55 places the ALT about 48 cm above the floor. When I sit in a chair, my ears are about 114 cm above the floor. I am very tall so lower that number to 100cm. That puts the listener's ears 50 cm or more above the 7-4 ALT. If your estimate is correct that would put the listener's ears about 42 cm below the ALT on the new speaker. In other words, the difference in height between listener's ears and a 7-4 on a BV7 is the same or greater than the distance between a listener's ears and the ALT on the new speaker. I do not recall anybody here ever questioning or complaining about the fact the ALT on the 7 being too low. If it is acceptable to have an ALT 50 cm below the listener's ears, what is the problem with it being 50 cm above?
Razlaw, might be the case. I'm not going to start arguing about that. But speakers are usually not at a set distance. Who sits 50cm from a TV? My guests often sit very close to my speakers if it's crowded at a house party.
What I can't digest is how awful they look!
Reminds me of a bad bodykit for a car.
Razlaw:The only 50 cm I referred to was vertical height. Not distance from from TV.
That I understood. You misunderstood me.
Saying that an ALT speaker has a dispersion angle of 30 degrees, would mean at normal distance from say a 50" TV it will most likely have no problem getting the angle down enough to hit you. I sit about 4-5m from my BV5. I sit about 4m from my BL5's, but say a crowded house party, or a small apartment the hight of the BL8003 ALT might become a problem.
I say might, as it may not be a problem at all.
My biggest problem with the darn thing is how ugly it looks.
Gatex:read patent papers
The patent papers might define whats protected but not the physical laws.
BeoBoy68:Can you answer to my question Geoff Martin ? Thanks.
You cannot question Geoff in the fact he's always happy to answer our questions. He's probably just very busy at the moment... He does have a mildly important role at B&O which might keep him fairly occupied you know!

And I doubt whether anyone at B&O is going to answer questions about a product that still hasn't had an official launch.
Hi, Geoff
I hope You can help me with a question regarding the "sound modes" for the Beovision Eclipse. I have a pair of Beolab 5 connected to my Eclipse as front speakers and for rear speakers I have Beolab 3. I have made two speaker-groups, one for music (2xBeolab 5) and one for Movies (5.0 with Beolab 5 and 3). When I use my Music speaker preset with just two Beolab 5 what sound mode should I use:
a) Music or b) Custom
What is best when I just want to listen to 2.0-channel music with my connected Beolab 5 to the Eclipse? Is there any sound-difference between "music" or "custom" sound modes when I just use 2.0-speaker preset with Beolab 5 as front speakers?
Best RegardsMartin StrömSWEDEN
