Subwoofer experiments can be enlightening!

A great video on how subs interact with each other and more:

Very inteersting. So sealed subs avoid a lot of problems but have lower output? Also would dsp with controlled phase delay avoid the problems of using multiple subs?

Yes, they actually demonstrate that in the video.

I am personally surprised that this thread got so little traction? Maybe it further demonstrates that the prevailing majority of members here are strictly two channel listeners.

Well I somehow missed it when first posted. I love the way they move around the microphones and show you what is happening as they talk about it. I've done similar with subs in my HT surround setup until I think I drove myself batty. Oh well, I recovered I think.......

Great introduction, really good if you a have never looked into these things prior.

Thanks, hadn't noticed before, always up for something sub. tho . Interesting demonstration/explanation. Outdoors or large halls like that are just a bit different than using them in a typical home room, tho .

I missed this the first time posted, too. I found this very informative. Lots of whys gets answered, like why do some speakers have such a choppy looking frequency response overall, and why it can’t be completely soothed out by EQ alone.
Thank you, Adam! I really liked that video.

Missed this, too... very cool!

The video has almost no relevance to subwoofer behaviour in domestic environments.

The explanation of the port is miss-leading and way more convoluted than needs to be. A port is a Helmholtz resonator. If you have ever created some sound from a recorder or blowing into bottles you can understand what a port is.

The effect of multiple sub use has no relation of multiple sub use (MSO) in a listening room. MSO is for managing standing waves. In open air there are no standing waves. What they are trying to explain is cardioid sub design.

Never said it was. Just said that the video and the sub’s interactions are interesting and I love videos that help us learn stuff. Slow your roll a little. Not everything needs to be confrontational or a chance to Win an argument. Yeah, happy holidays to you too.

I was not confronting you Adam nor trying to win an argument. I did say “they” to be clear. I was simply discussing the video as you suggested we do.

You seem to have missed my signature too

You are leaving out isobaric and bandpass enthusiasts.

Nahh, just that things are moving so fast that a new thread ends up on page four of "New posts" in a blink of an eye

Well, the narrator said "church" so I stopped listening. No reason for religious stuff to interfere with my Christmas spirit.

Jokes aside, the practical demos were fun.

I guess that’s a good problem to have..

As a former Sailor, I always loved to see a Port. As a drinker, not my cup of tea.
