Opposed subs?

2 subs mounted opposing directions inmho is ebay enclosures Inc.
That said...If anyone gets results from an obvious phase issue its thru testing and extensive installation trials. Even then I would wager its a specific bandwidth. User preferred and only viable due to his specific install.

?

2 subs mounted in opposite directions or face to face would be wired out of phase, properly wired, phase issues? Not following...

Maybe ask if he has an example whether sketched or pulled from archives?

Definitely an interesting subject to delve into. They are direct math equations. 2 separate subs= 4 times the box, 1 sub= 2 times the box, 2 iso subs= 1/2 times the box. I do not know if that makes sense but it is catalogued in my mind that way.

Sounds about right.

But the young gun was insisting otherwise. I just couldn't think of anything where his claims made sense.

I think I just saw a video of what his claim is-

There is a lot of information that he boast that are compromises in design here. Ported subs roll off quicker but will play lower. Using isolation feet with ported subs, should not use isolation pads/feet (not spikes) on subs, not so, use spikes to couple as they should absolutely couple with the floor, common misnomer (spikes are great for subs, isolation pads or butcher block/cement slabs for mains).

Internal vibrations can be negated pretty much entirely by good design and build techniques. Don;t get me wrong, I like sealed subs, use them in my car. For home listening in my dual use stereo/7.5.4 Atmos setup, all 5 subs are ported.
