Hi Jeremy,

I would go for the Beolab 6000 due to looks since they fit better (imho) in a fairly large room.

Concerning sound I concider both of them equal although there are opinons that say BL4000s are better.

Don't let us decide. Speakers can be a very personal choice! You may find you prefer the 4000s to the 6000s or the other way round. Your dealer will be more than happy to demo them to you.

Well personally I am a fan of the BL4000s. I would make my choice based on what speaker fitted the space best and looked right in the room. Interestingly there are some brackets available now to mount the BL6000s on the wall and they do look quite smart I think. The BL4000s seem to have a rounder more fuller sound to me that the BL6000s. I also think they look very stylish, especially wall mounted. I am sure some other users can give you more specific information as to what is considered the more powerful and better spec of the two. All the best.

Get the 4000's mate and you wont be disappointed, although saying that others will say the same about the 6000's. I would take Alex's advise and go to your nearest dealer and test both pairs. I think the 4000's dont look like any other speaker on the market whereas other manufacturers make similar looking speakers to the 6000's. Get the 4000's in black.

Alex is quite correct - speakers are a very personal choice so you need to listen to them first.

To compare them, they boast the same amplifiers but the 4000 has a volume of 4 litres compared to the 6000 which has only 3 litres. Speaker volume makes a difference to bass reproduction. The tweeters are the same but the 4000 has a single 11cm woofer whereas the 6000 has two 9cm woofers.

Not wishing to prejudice you, but I have heard one well known figure in the B&O firmament describe 6000s as a piece of drainpipe with some car speakers tossed in it. Unfair obviously but the 6000s are in my view best suited to rear placement. 

From a personal point of view I would say yes, the 4000s are more visually attractive. I'm a big fan of the way the 4000s look, especially in blue.

However, another way of seeing this is that there are plenty of speakers on the market which are the same size as the 4000s and still produce a large, good sound (although they generally look revolting and aren't as flexible).
There aren't however, any speakers on the market which are the same size and shape as the 6000s and produce a large, good quality sound.

The choice is yours. I wouldn't want to say whether BeoLab 4000s are better or worse than BeoLab 6000s, they're comparable; just as the BeoLab 8000 is comparable to the BeoLab 3 but still very different.

I was never a big fan of my BL6000s. Can really remember how the performed now, but I've never looked back since moving up to the BL3s. I think they sounded 'flatter' than the BL3s.

If you're going to consider 4000s, why not consider a mint second hand BL3s?

The BL4000 are really appreciated on this site, I don't like them design-wise, so I would go with the BL6000, they are stunning to look at, and the sound isn't bad.

As Alex said, don't let us decide, listen to them, look at them, and you'll surely choose the right one for you. 

Welcome to the forum! I really like the BS3000, did you get the version with the larger or smaller CD clamper?

Well the first question that came to my mind was, how will you be using them?

If you are using them as main sterao speakers in the room i would go for the 4000's on floorstands (seems you're comparing them to floorstanding speakers). Personally i would only buy 6000's if they were rears as i think they look beautiful from behind.

Arrange a home demo with your dealer, this shouldn't be too much of a hassle as they are lighter beolabs to move around. I'm pretty sure you'll go for the 4000's if you compare them side by side but some don't like the way the 4000's look! I bought my 4000's for sound reasons at first and wasn't all that amorous about the way they looked... after having them for a couple of years they've become my favourite B&O speaker aesthetically (bar BL5's). After all the time i've had them i'm still impressed when i buy a new CD by the wholesome detailed sound and the extremely natural treble.

At the moment i'm trying very very hard not to buy a second pair...
