Hi there,

When I first bought my lab 9's I nearly returned them as going from 8000's I could not get used to the sound.

I reduced e tweeter two clicks on on speakers and one click another.

It was just to much treble for my ears.

Sound is different to each person so it's up to you

All I advise is to mark the original position on some paper in case you want to revert back.

Each speaker is tested in the factory and the settings set per speaker I believe. Once each speaker is tested it gets a value and that value corresponds to a number in the table that they should be set to

I love mine now but at first I hated them

Hi Seanie,

Thanks for this very helpful reply.

Could you please tell me what the values correspond to (i.e: switch position 3 = 0,3 - 0,7)

What do 0,3 - 0,7 stand for? Decibels? Does that mean if I'm closer to switch position 0 that the tweeter, midrange or woofer sound louder?

Let me know please.

best,

Hi there

I dont know what they stand for but i remember that zero was lower than the higher numbers.

I also remember that they acted as a simple volume control for each speaker

The values given are the difference of each speaker unit to the reference speaker B&O used for the original developed speaker when calibrating sound. The values are measured in db.

Hi Seanie,

Thanks for your reply.

Do you remember your settings for each speaker?

Hi Martin,

Thanks for your answer.

If I understand, the more I'm close to zero the more the decibels level per speaker (tweeter, mid and woofer) is high?

Seanie tells that "zero was lower than higher numbers" that means to me that the more you're close to high numbers, the more the speaker decibels level is high.

Isn't it the contrary with your explaination?

Let me know please.

ok, I try to explain, let's have your BV9's for example.

The speaker consists of 3 speaker units - Woofer, Midrange and Tweeter. B&O, when designing the "master" version of the BV9 had speaker units with given db values per 1 watt input power. Let's say the woofer had 95db at 1 watt, the Midrange 92db and the tweeter 97db.

When making speaker units, let's have the woofer here with 95db at 1 watt, every speaker is a little bit different from each other. One needs 1.2 watt to have 95db output, another only needs 0.9 watt to have 95db. so when replacing a speaker you have to adjust this difference to get the same listening experience with the new speaker as you had before replacement.

This is what I know about these values.

That's very interesting, thanks!

So if I understood what you explained, if I'm closer to zero, the tweeter/midrange/woofer will be louder in terms of decibels, right?

If I feel, the midrange is a little low, I can set it to 3 instead of 5 and it will make it louder?

Sorry to ask, but I want to be sure I've understood.

Cheers,

Looking at the diagram you posted in the first post, yes it looks like the setting 0-9 increases the resistance.  I think 9 would actually give the speaker drive itself more power, thus compensating for the (-) value on the speaker drive itself.
