Hello, I would like to make a configuration on the stage, namely: 4 speakers with 2 subwoofers will be on the stage and 4 subwoofers in the middle of the stage, I will have to add delay, but what do you think it will sound ok? Is it okay to place it like this?

What is the purpose of placing them in this configuration? Have you modeled the coverage yet? I don’t see the purpose of the subs up on the stage having the line in front of the stage if properly delayed in an end fire configuration, can be steered to achieve certain coverage goals.

Because the tops will sit on the rod directly in them that's why I want to do this.

If you are just using the subs on stage as a stand it will probably sound better if the stage subs are turned off.

My thoughts exactly a last time I  checked speaker stands are cheaper than subs.

If appearance is an issue a couple of sticks of truss, baseplates and top plates plus a couple of truss warmers (triangular LED lights that fit inside the truss) give a very sophisticated look.

To the OP are you delaying this subs individually?

What speakers are you going to delay and why?  What are you trying to accomplish?

Delay can both help and hurt at the same time, it depends on what is most important.

Do you understand what different delays on different speaker can do?  Do you have the tools and knowledge to properly measure the results?

Delays for subs and delays for tops to subs are done for different reasons.

That was why I suggested to get some stands or truss segments for stage.  That would be a complicated array.  I don't think the OP knows about controlling pattern with delay because he hasnt responded to my questions in any detail.


Merlijn free spreadsheet is a great way to play with different configs.

Agreed; this is no longer a simple 2D issue, but 3D.  Not only that, but ground bounce from the subs on the stage is another negative variable into the mix that will change based on distances to various surfaces.

Since the subs on the stage are merely expensive speaker stands - do like others have suggested and invest in some type of stands (tripod or truss), put the subs on the floor, space no more than 6' apart center to center, and use a delay calc to set per-sub delay times.

Good advice above.  If you are mixing ((by this meaning using) different brands of subwoofers together, without measuring equipment to determine phase relationships between the brands, you are asking for trouble.  At one time (for a long time) a positive voltage in a JBL sub caused the cone to move inward when with almost every other brand sub, a positive voltage caused the cone to move outward.  With two subs side by side, the bass would be mostly canceled due to the 180-degree phase differences.  It is even more complicated now due to the digital processing in most active subwoofers.  Phase relationship can vary greatly with frequency causing strong comb filtering when mixing brands.  More subs isn't always better.

[Nick Tims]

That was an idea, and yes I can measure distances, nothing is active, everything is passive, subwoofers are Void Stasys all.  The array tops are made by me , but I was curious if anyone had tried this placement.
