Those boxes have DSP and EQ built into them... |

LOL
I was just wondering about compression drivers & distortion, 2" drivers in particular, how much more hearing damage do you get from this distrtion? I trust my feelings and it hurts, so it must be some. In my own system my 1" drivers doesn't reach full power until above 5 khz, it's the bms 4540nd with polyester diaphragm, they sound awesome. I always thought it was aluminium or something, but the secret appears to be polyester and of course tiny diaphragm & high sensivity. I just found this comment about the subject elsewhere on this forum:
Sadly the vast majority of speakers on the market are sonic weapons,
the manufacturers know they cause hearing damage but most don't care and
it shows in their R&D. Anything that's using a compression driver
below 5kHz will do it and sadly that means 9 out of 10 of the 2 way
systems in existence as soon as you push them up to an SPL which you
need for a disco/live type event they sound absolutely god awful.

Every system needs tuning to the space it's in. Manufacturer presets are only a stating point to achieve a flat response in an open space. May well sound ok in a big open field, but put the same rig with same settings in a concrete box.... It'll sound totally different. Almost every box ever designed has some sort of eq applied to it..

Of course, and then again no:-) F1 aim to sound perfect (outside) with no eq.
My system was far better from "factory" than the martin tops which should supposedly be factory set. To avoid the use of a lot eq inside the dispersion and damping have to be thought thru, this is number 1 way to avoid eq. |

12 subs to 4 small tops? sounds just about right for balance... But all joking aside i don't know the room so if it works. imo definitely need at least 4 tops per side to start working as spec, the more the better. They seemed to sound quite disconnected with only a few boxes with harsh highs as described. One thing i noticed on the w8lm was the lack of, using the term lightly, 'throw'. Question is; Does the club actually need a line array with WSX? or was it put in just because? Again not knowing the room, but I would have thought a concrete building with low ceiling would benefit from point source boxes and a different choice of sub.

suggestions are welcome:-)
I think the older point source 12/6.5/1 floodlight iike tops from martin would do better. But they probably need a quite high crossover, which again might lead to a more boomy sound from the subs. @WSX: do you think they have too much directivity or throw for the room? Would ported be better? I wouldn't mind putting other brand tops on top, I like mixed marriages, could be F1, xtro or something point source with a crossover no higher than 120hz Edited by tv00 - 28 October 2014 at 11:49am |

It 'throws' less because it's a wide dispersion box. With just two boxes a side you won't get coupling to compensate on the mid or low end, hence why the top end is still going strong and it sounds harsh. Edited by toastyghost - 28 October 2014 at 12:14pm |

oh don't get me wrong Toast, i mentioned exactly what you have just said when it was set up last time i heard some. It just struck me that it did drop off quite quickly compared to other similar cabs... not necessarily a bad thing as it helps keep the sound where you want it.
I know the dispersion is one of the main attractions for this kind of box and it does it well, but in small rooms this can cause more problems. Especially on hard walls. @tv00; i don't know the layout so can't advise fully but sometimes less is definitely more. WSX are good cabs, but it does depend on the venue. All the energy can end up in the car park and not the dance floor.

Still doesnt explain the 200hz honk that was there with three a side, can only imagine that gets worse as you add boxes! Just not a very flat response unfortunately.

Very true King. I can't remember the factory settings for these used but it did sound a bit off... still at least you got a result and some compliments out of it all :)

I think what the poster meant was to look at the settings for W8DVQ and use them on your two a side of W8LM. the DVQ is basically two LM a side, so if you use the settings for DVQ to set up your boxes it'll sound very close to martin's own settings for that size of array and i'm sure an awful lot better than the actual settings for W8LM when you only have two a side. k |
