I view of the fact I have two pairs of S2 drivers, I'm intrigued by the thought of running them a la Romy, i.e. high and low. So, in addition to procuring a pair of Big Mama horns, I'm discussing with Martin the prospect of getting some higher frequency horns made to take over from the 160s at higher frequencies, up to the S2's natural roll-off. Some advice regarding the cossover frequency and how best to integrate them swould be welcome. My initial thought was to run the 160s up to 2.5kHz to get as much of the mid-range covered by one driver, but it's been pointed out to me that crossing lower (approx. 1kHz) should be better. Some advice on this and suggestions on a suitable flare rate would be welcome.

There are many debates and recommendations out there insisting where to put and where not to put a crossover points. People bring different arguments, insisting where crossover should be and where it should not be. I personally feel that those types of arguments are completely bogus or juts merely irrational if do not take under consideration silly arguments.

There are NO RULES where crossovers “must be” and there are no relationships between crossover’s location and preproduction quality of a specific instrument’s group or a specific voice range. A proper performing crossover (use my principles of “Vertical Continuity”) is not auditable. If the problems around a crossover point are auditable then it does not mean that you need to move crossover up or down, into the “less dangers frequency range” but rather it signifies that you need to fix your damn crossover/installation.

The selection of the crossover point has absolutely no other rational then evaluation the performance of the given channel - driver within the given loading and the given environment. This assessment shell take place in context of the neighboring channels and where the given channels begin to demonstrate weaknesses then the 1 octave above (depends of the crossover type) will be the point of the channels merging.

I strongly insist that it should be no other “intellectual reasoning” in selection of the crossover points besides the observing the actual performance (individual and integrated) of the given channel and making a decision based upon the actual results.
