Subwoofers
should the sub be cut away from the resonant frequency?

[QUOTE="surreal89, post: 8869367, member: 690803"] good evening, I have a Gorilla Bass 30 brand sub and its resonant frequency is 32Hz. given that for woofers, mids and tweeters they recommend having the speaker at at least a third of the resonance frequency, I was wondering if this should also be the case for the sub. but cutting it by a third means making it work around 50/60hz up to 70/80.. but in this way the sub wouldn't sound at all in my opinion. I have a processor and would like to understand how much to set the high pass to make it safe. as regards the low pass and crossed perfectly at 70hz with the woofer. I also take this opportunity to ask you another question. given that the amplifier does not allow me to completely exclude both the subsonic filter and the low pass, I would like to know if it is right to do as I did, that is, I set the subsonic filter of the amplifier to minimum (15hz) while the low pass is fully open (at 150 Hz). this way I can do both cuts from the processor. Is this the right procedure? or did I do something wrong?..do I risk some overlapping of the cuts? or maybe I should close the low pass of the amplifier a little? I set it to the maximum so when I put the 70hz from the processor I don't risk overlapping. thanks to who helps me. I'm Italian, sorry for the pronunciation. [/QUOTE]
