For a sound + movie solution i do agree that i should use 4 BL 5 or 9; i'more an audio lad, but of course i do like to see some movies of course.

My main doubt is to have the most of BL5, but i have to obey to the specs. of them; the distance from the walls etc. etc.

I heard a pair of BL5 and a pair of BL6000 @ my local store and they sounded quite good (your solution at home), but perhaps i have to hear the solutions @ my home.

I'll check the room dimentions and i'll post a new thread.

 

For 2.1 stereo sound + 5.1 movies the best combination is 2 lab 5s and 2 lab 9s - best of both film and music without breaking the bank.

For music in enhanced stereo (4 speakers at same time) best is 4 speakers all the same - lab 5 rears instead of lab9 rears won't improve movies very much though - not worth the extra £5000 if used only for movies. Worth it if used mainly for music in enhanced stereo.

For 5.1 channel music and films, best is 5 lab 5s - but this is too expensive and overkill for almost everyone especially if you don't listen to 5.1 channel music it is a complete waste of money. Only worth it if you listen to / mix music in 5.1 channels ie people like Dave Moulton.

But yes, if you can find a store that has 4 beolabs 5s for you to borrow then try them out at home anyway hehe I would just to hear what 4 lab 5s sound like lol !!  hmm not sure what I'm doing in over my holidays yet, this could be an interesting project hehe. 😎

Well, four BL5s sound quite disorienting on most kinds of music, to be honest. I've heard it several times. And it's a really overkill way of achieving SPEAKER 4 or 5 sound in a room.

I've also heard the BV9 with two BL5 fronts and two BL6000 rears, demonstrated by the person who headed the work on the BV9, who said the 6000s did the job as rear speakers excellently.

I wasn't going to involve myself in this thread, as this topic has been covered often here at BeoWorld, but there is little need for matching speakers all around unless you are listening to the 0,001% of the world's music that is created for matching speakers all around. Movies don't require it either. Good SACD recordings use the back channels to provide the hall/music stage ambience and true rear reflections, not to deliver critical musical information, and therefore do not require matching all around speakers. The new HD Audio formats may make enhanced use of the opportunities for storing higher resolution information for the other sound channels - but that involves extra work during production, and movie theaters aren't geared to process this -- which means you would be creating such mixes for advanced home theatres.

If you like to upmix two-channel to four or five channel, then as a personal preference you can go with identical speakers all around. But if you want precision sound placement in your media room, that's probably not a good solution. Everything will sound harder to place and larger than natural.

However - there is work going on at several brands with connecting the subwoofer info to the mid range "traveling sound" perspective. Usually, the subwoofer/woofer sound impulses can't/shouldn't be placed in space -- the bursts should just be there in the room. Anyone with BL5s will testify to the advantage of being able to deliver bass supporting a source either to the left or the right in a soundstage.
It's possible to move the bass if you have identical bass units in the four corners of the room. You then follow a traveling sound in the mid-range, and tie the bass perspective to this traveling sound, fading woofers up and down with Digital Signal Processing. You then get a bass experience that appears to accompany the other sound, lending weight to it.

Should that becomes a standard feature, you might want to look into at least placing subwoofers in the back corners. You will also need to have your own house as any apartment neighbours would be turning up to spit roast you!
