Something has occured to me, if you have your L1 off to one side & the B1 under your deck stand, do you find that there's a bass hot spot in front of you where the drainpipe is (partially) drowned out?

[Vibrant Sounds]

I haven't noticed one.

More likely is that there is a bass dead spot by created by those who use pairs of bass bins situated to either side of their rigs.

Sound is a waveform, and reacts the same as a wave in water would. If you throw two pebbles into a still pond about a metre apart, you will see that where the ripples meet in the centre you have a cancelling effect (ie a dead spot) if you stuck the two pebbles together and threw them in you will have much bigger and more powerful ripples (hence the reason why acoustic coupling of a similar powered cab gives a 6db increase rather than just a 3db increase). It also matters where you stick your subs, in corners and on the floor is best as because low frequencies are monoaural and travel well through structures the more surfaces the bassbins are near the better the bass.

So even with L1s it is best to site all your bins together and near to as many surface areas as you can.

What people have to realise is that the L1 is basically just a mid/top speaker the only difference is it is a line array system hence it has little reflective potential from the floors and ceilings as the sound moves out in a horizontal plane rather than as a circular wave as is the case with normal cabinets. Again the acoustic coupling of many small speakers adds to the sound and effect, and the lack of reverb and echo bounced from the roof and floors adds to the clarity and lack of muddiness at distance.

I might sound a little thick here....

but i don't follow you mate,

What is a L1 & a B1

:S:S

[djsteve10]

oooh i follow now

the bose system

:bang:

A joke, right?

Any talk of 'drainpipes' in a disco-related topic and you've got to be talking about Bose! :p

Ok so it's best to stick the whole lot in a corner ?

In that case wouldn't the DJ, in a lot of situations be in front of that?

Steve, you could stick what you like in front of it, you ain't gonna stop the bass frequencies. They travel through the walls and floor, hence why you place them in the corner in the first place.

Have a look at any surround sound system manufacturers websites. If they advocate the use of Subbass's then they normally tell you to face them into a corner normally behind a chair or settee.

Our bass bins are designed slightly differently, but to get the best results they have to be within half a wavelength of the walls or floor to achieve coupling. By placing your bins together, you will get a much louder and fuller bass sound (Hence why the more expensive bass bins are dual drivered) lower frequencies are produced better. In fact even the B1s have dual 6.5" drivers in each cabinet.

Not had to resort to this though 18 drivers in there.

I suppose another layer and he wouldn't need a deckstand.

[Corabar Steve]

I was thinking more of a comfort issue for the DJ being infront of the pole

[Vibrant Sounds]

Sorry Steve I thought you meant thes subs.

No, Mid/top frequencies travel differently than sub bass frequencies and are much more easily attenuated.

The best place for a single L1 is right in the middle of the stage/wall facing down the room allowing an equal distance on each side. This allows the sound to spread equally down the room. If using a pair of L1s, you would set them up as you would any other mid/top cabinet, to either side of your room.

If you were using a single cabinet and running in mono where would you stick it. In the old days most DJs set up their single cab in the middle of their rig, or to one side if they had lightscreens.

It would not be too long before you were deaf if you constantly set up in front of your L1s.

[Corabar Steve]

Sorry Steve I thought you meant thes subs.

I did initially, but out after what you said about best placement being against as many surface areas as you can.......

.... just got me thinking

To be fair though Dave, the demo at DJ Show North wasn't a great one, with other manufacturers playing loudly too. The venue wasn't exactly great for acoustics either.

I like the look of them and still want to hear a 'proper' demo.

[Vibrant Sounds]

Nah! They're rubbish everybody say's so! I wouldn't bother.:sofa:

[djsteve10]

I heard a demo of this at a Local NADJ meeting, I wasnt impressed overall with the system but yet again he only had 1 stack and 2 bass bins, would be abit different hearing yours with a left and right and with all them bass bins.

[BrightLights]

I haven't heard them in the flesh, and I'd be interested in doing so, but I get the feeling they'd be best suited to applications where everyone in the room wants to hear the sound but not necessarily all that loudly. So they're probably ideal for a band or singer, but I can't help wonder if they can shift enough air for a typical disco scenario. I've read a fair bit about the science behind line arrays (I'm a geek, ok?!) and they do help carry the sound further, but there's no getting round the fact that for a lot of volume, especially at low frequencies, you need to move a lot of air, for which you need big drivers. Obviously you can have a big pile of B1s like in the photo earlier in this thread, but if you have to do that to get the level of sound you're after haven't you just negated the whole point of using the system in the first place?

I'd love to be proved wrong as it'd be excellent if they do work well for discos...

Clive at CRS uses them - pop down to his shop and ask him to demo them for you.

[Vibrant Sounds]

would be abit different hearing yours with a left and right and with all them bass bins.
That wasn't mine, some bloke in the States. I only have a pair of L1/PS1s and four B1 subs. That lot would have cost me about another £2000.

[djsteve10]

aaah right i get you now....

going off the subject but isn't it something when djs in the states dont use hardley any lighting, they charge extra for it apparently!

[Solitaire Events Ltd]

That's not completely true Some do and some don't.

[djsteve10]

yeah american djs like to be small with their set ups too, nice and compact ... its eithter that or they go for a huge rig lol

[BrightLights]

Does he? Now that might be interesting. Mind you, the shop's only a small space, which might make it hard to judge them in terms of volume capability. Just about anything would sound loud in there, especially as it's in the middle of a sleepy little village!

I think you're generalising a bit too much here Steve. I'm not sure where you are getting that info from, but go on a few U.S. forums and yo might not find that to be true.

That's the problem with any sound demo though, isn't it? It might give you an idea of the clarity though.

True, and I've always been interested to see if Bose PA kit is any better than their hifi stuff. I've never really liked the "Bose sound" to be honest, but that's just based on hearing other people's overpriced home cinema setups and therefore hardly scientific!

[PropellerHeadCase]

I believe the correct term for the Bose sub is 'Toaster', so a full set is a drainpipe and toasters rig :D

Ermm--not sure about this comment---

All the Bands I ever played with ( as support and sometimes the other way round) ) blew everyones heads off! :D :D :D

We know thats what the audience would like( not so loud and clearer ) but it never happens:eek:

The longer it goes on the louder it gets---and if no one is dancing---it gets even worse--I know--ive been there:eek:

[BrightLights]

Oh alright, but you know what I mean...

[Arnold_disco]

But in a mobile situtation you could be anywere?

[Corabar Steve]

But in a mobile situtation you could be anywere?

But not in a room with at least 10 other sound systems going at full volume.

[Arnold_disco]

But not in a room with at least 10 other sound systems going at full volume.

I know that would of made it worse but i mean that the acoustics of the room is beyongd your control.

[Corabar Steve]

Fair point, but it would be highly unlikely that you would be doing a gig in the same sort of layout as DJSN. Which was what Darren was getting at in the post you quoted.

I did that demo and it was awesome ! That 1 stack does me fine for gigs of up to 200 people, horses for courses I suppose. Shall I bring it to BPM with me to give people that "proper" demo?

Please do.

[Paul James Promotions]

Unfortunately can't make it to BPM, working on both days. Shame, would have liked to have given the L1 another chance, as i have only heard 1 pipe and 2 bass.
