Wide baffle 2 way speaker or not

[Harolda]

I am thinking of putting a seas w15cy001 and a hiquphon OWI in a wide (curved) baffle. The speaker will be approx 100cm high and the lower part will be sandfilled, because i do not need al the volume for the seas

As i have learned, baffle step compensation can be avoided by a wide baffle design. Is there a way to calculate the width of the baffle to avoid a baffle step compensation

There will be no cross overs in te speaker, it will be active and driven by gainclone amps. The (passive) crossover is put in the pre amp and uses B1 buffers.

You can use EDGE to simulate your baffle:
Home of the Edge

You will find that the baffle-step cannot be avoided, only pushed downwards in frequency as the baffle size is increased.

a good way to deal with baffle step is to add a .5 way driver, crossed over 1st order at the baffle step frequency.
Saying that, I built two sets of 2.5 way speakers using the same drivers, one set was in 30cm wide cylinders, the other 50Cm wide thin box. The wide boxes sound MUCH more solid in the low mids - drums sound fantastic. Go wide...
