we have recently reloaded our a hog scoops with beyma drivers. (theres a big long thread about it elsewhere)
on our first proper test at the weekend we upped 35hz by 3db on the eq to give a heavy sub bass. is it bad to to this, they were being run off a pl380 one a side so 1500w the driver is rated at 1400w the amp was flashing the -10db lights is it ok to run like this or are we likely to damage drivers?

If you are boosting at 35hz, what is your HPF ?
Also, expect your sub amps to clip real quick. Edited by levyte357- - 11 November 2014 at 11:57am |

excursion minimum is at 35Hz so shouldn't damage driver as long as the q of the boost is 6 or narrower. not sure it will improve the sound much though

Had advice from a very good producer narrow q is not recommended and not usually used for bass frequencies. Aint sure why and does it even apply to PA or just to production.

No you can use any Q factor you like for EQ, in any situation. Just depends how you want it to sound. I can't think of many applications where a very narrow boost in the bass would be useful, but I used to use a Klark Teknik DN410 on maximum Q (I think that's 20, so a very narrow filter indeed) to knock out 40Hz from PA systems to stop decks feeding back. It left the rest of the bass intact you see. There was no subjective change in the bass at all when the EQ was switched in, but the decks stopped booming completely.

Yes you are quite right, I actually missed my point there haha. Narrow q is good when cutting a specific freq and wider for boosting.

DN410 narrow end is nominally 1/12 of an octave, so one semitone. Utterly lovely kit.
