What Frequency Response is Actually Needed for Low Tuning?

[Geri O]

All of this is why I’m glad there’s guys like Andy and Tom Danley that can build a bass cab for every need so I can pick the one that serves my needs and i can concentrate on playing music.

We play 24 of these at my revived day job these days….

Hi.
I have a 218 cab with 18G550N from Beyma. The box is heavy as hell and 250 litres. Is connected to a CREST CA18 and Ampeg SVT3 pro.
I had to bandpasse from 25Hz to 150Hz to keep it clean and safe.
If I play in a small room all that you get is a muddy bass beacuse it requiers a big room to get that wavelenght work (13,72m at 25Hz)
So for big venues is fine but hard to handle but for practice is not usefull by my experience.

A lot of folks blame the subs for poor sound at low frequencies. A poorly setup PA is the cause, not the subs.

Maybe, but pretty much always the subs are the part that is most badly set up and turning off the subs often improves things. Hence I am generally concerned when I see subs in a small venue as 90% of the time the set up is poor. Even in some larger venues it seems to result in a muddy mess, sadly.

The bad part is that we often only hear the back of the subs on stage.
I played a couple of gigs with competent techs running high end systems. There were no annoying sub frequencies audible on stage.

Oh, I was out front checking how things sounded at that point, not on stage...

Too many techs don’t know how to slot in the bass guitar.

So, in your neck of the woods, nobody knows how to set up a PA properly.
