I have decided to go with the SM 100F's.... I will give a report when i get them.. So Ivan how would you then set the xover?? Say subs from 30 to 60 and the F's from 60 up??
Thanks
It depends on whether you are talking electrical (which most people do) or acoustical crossover-(the IMPORTANT one).
Since the subs are often run much hotter than the mains (typically 15dB to as much as 25dB) the acoustical crossover is higher than the electrical settings.
It is for this reason that the sub low pass and main highpass are not the same freq.
Often there is a "apparent gap" in the freq response-but in reality there is not-due to the subs being run hotter.
For a TH115/Sm100F combo-I would run the subs up to around 70-80Hz (electrically) and high pass the Sm100F around 100hz. Those are just quick "off the cuff" suggestions.
Of course it also depends on what type of crossover you have and what it is capable of.
We do not have "official" settings for that combo yet.
It also depends on the power available for each of the freq bands. If one band is "running out" then it can be narrowed to remove some of the "strain" since there is a good bit of overlap between the boxes.
