Thanks a lot Bruce.
That's real simple.
I think too that it would be safer to leave the recommended HP at 40 Hz untouched and use a 24 dB slope instead of knocking the hell out of the cabs with the lower HP and use the 48 dB slope.
I could imagine that this would sound “warmer“ too.
Thanks
I tested my T39 with recorded music and found that the 24dB slope at the higher x-over point (45Hz, in the T39) was much more pleasing than a 48dB slope at 40Hz. The steeper slope, even at the elevated cutoff point, cuts out a lot of content in the recorded material I was listening to. It seems much of today's recordings have usable content in the 30-40Hz spectrum.
For live music, the 48dB slope wouldn't be too noticeable. And really, even with recorded content, 99% of the general public wouldn't notice the difference unless they were looking for it... even with EDM.
I'm pretty sure the "one size fit's all" recommended limiter and high pass configurations are based on minimum width cabinets and are figures rounded toward the conservative side. However, I doubt there's much left on the table either. My initial instinct was to achieve the most I could from the cab. But, my mind has settled into a belief of/that, if I'm running that close to the limits on a regular basis, I need more cabs so I'm not constantly at the limit. Or, a different cab, if the limit I'm constantly pushing is the cabs bottom end extension.
Still, I'm fairly sure you'll be okay with 50volts on a 24dB slope at 35Hz with 4 19" cabs. Bill would be able to verify.
One of these days I'm going to take the time and learn to use Hornresp. Which I'm pretty sure is the tool Bill uses to model the cab/driver combo's and also derives the power:High-pass cutoff excursion limits. Would love to see the effects of all the different variables.
