Nothing wrong with that, we all start somewhere. OK, it's pretty clear you're not very experienced or knowledgeable about car audio or audio systems in general. I enjoy the massage and the bbass produced by the x12 does not hurt the ears. Sounds good loud or quiet, so why ever have it quiet. I don't think the x12 and this box picks up much of anything above that. The only music I've found that hits good is newer rap set below 40hz. I love this idea as I know my EDM music could hit a lot harder. From what I understand some can take a range of upper frequencies and lower frequencies and convert them into a lower, effective frequency for your woofer. For 60 bucks there are some nice soundstream and other units that seem to be pretty awesome. I saw some bass drivers on sonic electronics. So I want to get the equipment I need to have it be maintenance free. I'll play or modify tracks either way, but I still want to be able to listen to new music without worry. Otherwise you'd have to inspect all music to make sure it does not contain anything below 32hz to play music at max volume safely and have the most bass, for sure safely. Therefor a SSF should be used to cut of all frequencies below 32hz if that is used to set the gains correct? However in the guide it states that if you set the gains with a 32 hz sine wave recorded at -0db, if a 31hz 0db tone is played it will clip. I have read the bcae websites guide to setting the gains using an o-scope and understand the tones / Concepts. Now the use of attenuated tone will result in audio played that is recorded at stronger levels to potentially clip.Īs for a SSF, Harrison Labs makes FMOD filters you can get. 10dB would be the most I'd use, but some go as far as -15dB. Thus, one used attenuated test tones, as music is dynamic and recorded at varying levels of attenuation. Using a test tone of 0dB however will result in lack luster performance. If you use a 0dB recorded tone, clipping shouldn't happen unless in the recording itself. You set your gain using test tones but it's the recording level you are needing to worry about. Tuning to 32Hz using an O-scope? Are you meaning setting your gains using a scope? My point, the frequencies above 40Hz (if set to such) will still play, but they will be attenuated XXdBs/octave. The LPF has a roll off slope, may well be 12dB/Oct, but without knowing the amp, I can't be certian. It is often said/recommended to set a SSf filter within 5Hz below the tuning of the enclosure, though I've heard it said a SSF must be set within 1/2 an octave below the tuning, so I am ASSUMING the within 5Hz below tuning is the extra precaution way to go. It would be frequencies of say 28hz and lower that would be of more concern in terms of potential damage to the sub. You need a SSF to protect the sub from unloading below the tuning frequency of the enclosure, though truth be told, damage doesn't occur from say a 31Hz frequency when tuned at 32Hz.
