LoudPackRacing Posted December 22, 2015 Report Posted December 22, 2015 I've been reading on crossover slopes for a while and am still confused. So let's say I have my sub crossed at 80hz. What happens when I do 80hz@6db or 12db or 18db or 24db.what would you recommend for subs? I don't want phase issues or have to reverse speaker polarity I just want to know which of these would be the normal so to say.
reedal Posted December 22, 2015 Report Posted December 22, 2015 "Normal" would be 12dB/oct. but it's all about what you like. I have mine set as steep as it can go on my 80prs SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32
mothra Posted December 22, 2015 Report Posted December 22, 2015 simple way to understand it. if you have a low pass filter crossed at 80 hz it will still play frequencies above that just at a lower "volume" the further you get from that number till it gets to 0. the higher the slope number is the sooner it gets to 0. so a 6db/1st order will play all the way to 150 hz, 12db/2nd order will play all the way to 125 hz, 18db/3rd order will play all the way to 100 hz, 24db/4th order will play all the way to 90 hz, etc.... not exact, it's a bit more but that a good summary to get an understanding. if nothing changes, nothing changes You don't know what you don't know, till you don't know

Ahh now I see exactly where you are coming from thanks.what about mids and highs how high up would they play?
