Your question is simple and straightforward. The answer is not!Hi guys. How much of db increase does MB frequencies (assuming its 50-120Hz) need to get the strong chest slam if sub is not NF? I have a 23x14x8 sealed room and my subs are placed 75" away from MLP. I have been trying to get that super punchy MB slam. Before I doubt my subs, wanna know if I have dialed them properly. Currently this is what I have
30Hz: 12dB Hotter
50Hz: 10dB Hotter
I have good room treatment and reflection is in good control and therefore, I can turn up the system fairly loud.
What subs (sealed or ported?)? What main speakers & x-over? Sub EQ? REQ? What measurement tools?
I find that boost centered at 63Hz is the most effective. It requires trial & error.
