I note from the information BeoLab 8000 | BeoPhile.com
"…The speaker’s technical specifications remained untouched until the MKII version was released in January 2003 (as from serial numbers 16992475) when it was manufactured with newer driver units which delivered extra bass reproduction at low listening levels…"
New style drive units can be seen here:
On ebay drive units can be found:
New style
Old style

My questions are:
  • Are these drive units interchangeable in terms of physical mounting and electrical characteristics?
  • If the Mk 2 drive units were an improved design with better sound, does putting them into a Mk 1 speaker effect an improvement in sound?
  • Has anyone experience of renovating BeoLab 8000s and any useful experience to share?

At present I have some 6000's but occasionally I see some 8000's on ebay for sale with damaged drive units and tatty frets. I'm wondering how difficult it would be to renovate and whether it would be cost effective.

MKII, does not mean better than MKI ... 

 

I have 8000. Problem is the size. Even the BeoLab 18 suffer from the same problems as the 8000/8002. 

 

They are beautiful to look at the 8000/beolab 18, prolonged listening is not tiring, but the HI-Fi is another thing.

The changes were more complicated than just a change of drive units from Mk1 to Mk2 as the crossover configuration was also altered and the speakers went from being a kind of 'two and a half' way configuration to two way.

Beocentral summarises it best: http://beocentral.com/beolab8000speaker

As a result, I would have thought that simply changing the drive units from one type to another would be a pointless excercise and very probably make the speakers sound worse!

Many thanks for the information. As mentioned my query is sourced not in upgrading an existing 8000 but rather to see whether buying a non-function pair of 8000's and repairing them with parts from ebay is viable. Looks like there may well be some pitfalls though!

Thanks again for the information.

Adam,

You have confused me with your comments regarding Mk1 to Mk2, as I thought that the change to 2-way configuration was made quite early in the production run of the speakers, (about 1995 according to the serial number quoted) and that the Mk2 came much later.

Perhaps someone could enlighten me further!

I believe MK2 was around 2003.

Ban boring signatures!

I know that B&O did upgrades for customers a few years ago were they modified Mk1 to Mk2. I was once consider it when one of my Mk1 speakers failed and needed repair. In the end I choose not to. The reason why is because I don´t think the difference in sound between Mk1 and Mk2 are that big. I think its better to spend money on a subwoofer if its deeper bass reproduction  you are after.

I've not heard a B&O subwoofer but I note that the problem with the bass from my BL6000's is not that it is not loud enough, it's that it is rather uncontrolled and lacking in definition. I'm mystified as to how adding a sub, no matter how great, would solve this lack of definition particularly when you cannot turn down the bass response in the 6000's/8000's.

 

But as I said, I've not had the pleasure of listening to one in the flesh.

Although I have forgotten most of this, I believe that sounds about correct. Mk.2 got the ABL system, and it was a different change from the "2.5" to two-way configuration. Mine certainly aren't with ABL, and they have the two bass drivers simply in parallel.

I believe I posted the "borderline" serial numbers of different versions somewhere in the archived forum, they are listed in the leaflet that comes with new treble speakers (with the associated protection circuit upgrade).

It would appear that the BL8000 has a complex history (not surprising given the long production run) and that it is not simply a case of a Mk1 model and a Mk2.

Going back to the original post, in upgrading a Mk1 version to Mk2 specification, it looks like there is more to it than a simple change of drive units!

I found the old thread:

Take it with a grain of salt. It is based on sources, but... Big Smile

Hi mika,

 I did a quick read through the old post - could you elaborate a bit more on the statement that the Beolab8000 without ABL

Should be the more natural sounding version ?

I don't quite get it ! Also, it seems quite difficult to find a pair with such a 'low' serial number?!

Wonder why that is :-)

Cheers

I have never compared them side by side myself (and doubt I would hear any difference). That statement comes more or less directly from Beocentral:

Thank you - well received 

 Just gone through the article.......interesting though.

Maybe owners of those pairs with responding serial numbers hang on to them for reasons mentioned in the article.

I will continue looking for those  :-)

Cheers
