Subwoofer Placement, Best Place To Start And Methodology!!!

[@SealedOrPorted]

Send those heavyweights to opposite corners just like boxers lol appreciate you guys having Ed share his expertise.

[@Totalplonker]

Sonically I've got no complaints having my Rel subwoofers positioned in the corners (behind my stereos) but it's when I walk to the bathroom to take a piss they actually sound the loudest 😂

[@carlosolivia2044]

You opened the door to some really good thought regarding sub placement, however, for someone like me who does not have calibration equipment to identify where the null is, can you put up pictures of the ideal sub placements.? the explanations were good but we need to see if visually. Thanks for the time in bringing this up.

Is it better to put your sub in the corner, or put a bass-trap there (and the sub somewhere else)?

[@davemiles3387]

You’d think he could tell there was a null if he was an “audiophile”. Lol.

[@sirgriffinman]

You definitely can but that is subjective, less accurate, and you can't compare easily the whole frequency range. Use a microphone to measure and have graphs for each position allows you to find the best place for the entire frequency range.

Everybody says don't put sub in the corner and the only one gay says start with the corner lol.

[@DailyHiFi]

Who is this "everybody" you speak of? Name 2 established people who recommend what you're saying.

@@DailyHiFi I was watching this video from Acoustic Fields ''Don't set your subwoofer in the corner'' and a few others. After reading your comment, I did more research and found that you might be right about the corner placement of the subwoofer. It seems that opinions are mixed but generally in favor of corner placement

@@DailyHiFi This one is interesting first answer is from gemini AI Avoid corners and walls: Putting your subwoofer in a corner or right up against a wall can make the bass boomy and uneven. This is because bass waves build up in corners. Second answer is from ChatGPT Corner Placement: Placing the subwoofer in a corner can amplify its output because the sound waves reflect off the walls, creating a louder and more robust bass response. However, this might also lead to "boomy" bass or uneven sound distribution. My point is if you don't have IQ on the sub you can't compensate. Yes i know it will be a cheap sub. Means not very good, but you want to squeeze as much as you can from it.

Joe here. The best research on subwoofer placement has been done by Todd Welti at Harman. He has a paper which you can find online. To summarize, the corners offer the most room gain which can help with subwoofers with limited output, but they have worse seat to seat consistency. Mid-wall placement offers the best seat to seat consistency, but has less boundary gain than corners. More subwoofers are better for smoothing out room modes, with significant diminishing returns after 4 subwoofers. I would be weary of acoustics advice from AI chat bots. They're often wrong as they're scraping info from forums which can contain often repeated myths about audio. The output you've shown from AI seems to refer to common advice about speaker placement. If you ask it again if the same advice applies specifically to subwoofers, not main speakers, it might come up with a different answer.

@@DailyHiFi Thanks for the info about Todd Welti i will definitely check this out. Thank You again Joe.

Don't agree with the guest. Even if you have a null with one sub, when you add more subs, they cover that null. That's exactly the point of having more than one sub. Give me any kind of room and if have 4 or more good subs correctly aligned with MSO and minidsp, I bet my house, you'll have with flat response at any frecuency.

[@joentell]

I agree that using multiple subs fills nulls. That's the whole point of MSO. That's why I responded with my comment. I think of it like a loudspeaker crossover. We use each sub at the range(s) where they're most effective.
