When I went off the deep end with room measurements I concluded a sub couldn't fill a null caused by a room mode. Since a room mode is caused by resonance and/or room dimensions causing phase cancelation putting more of the missing frequency in the room would cause a proportionate increase in phase cancelation of that frequency.Kniferide wrote: Fri Jan 12, 2024 10:00 pm I just added a new sub to my room. It's the third one I've tried. I first had a little Jbl from a home theater system and it was flubby and weird, I'm using that as a sub off the synths in the live room now and it is more suited to that. I replaced it with a even smaller passive Pioneer sub from a home 5.1 sound system. It, because it was less cable of being a sub, actually sounded better, but still I could never get it in the sweet spot. The Adam Sub 7 was the MF Stupid deal of the day about a week ago for like $200 so I bought that. I have Adam T7V speakers in there now so I thought it might go well. It does. Using Fuzz Measure I was able to find the lowest peak my Adams pitched and tuned the subs mound to be an octave below that. Funny thing is, to just fill in the octave and not he hyping anything the sub is literally 2 clicks higher than OFF! Just barely on at all, but it sounds really good. I gotta get a foot switch to bypass it but its the best sub so far. I fight with Low end in my tiny room almighty and to the end. There are traps. Lots.
Any luck with subs in a small room?
Then again, placing the sub creates a source for the missing frequency in a different position which could interact with the room differently. Then again, again bass wavelength is so damned long.
This is more of an "I wonder" than an "I know". I bring it up because it's totally theoretical (I never actually tried a sub) whereas you're fiddling with it in practice which is worth more in my book.
But lots of traps, boy do I know that experience. Like add a cubic yard of insulation, shoot the room with the software, then see a whopping 10-15% improvement in a problem area. Repeat.
