I built 2 completely different subs. I am trying to get them to work together but not having much luck.
1st sub (S1) is a SVS DiY. 12.1 SVS driver in a 4 cuft incloser with a 4" port aprox 18"long.
2nd sub (S2) is a Dayton 12" DVC in a 3.0cuft sealed incloser.
Both subs have the same plate amp (Rythmik audio 350A)
As you can see in the diagram, I have each sub in oposite corners from each other. I have calibrated the phase.
I set the correct phase with S1 with the mains, then phased S2 to S1.
The mic was placed in the center of both recliners (Rec).
I am getting the same dB reading with one sub playing (S1) as with both subs playing.
My assumption was by adding a second sub (S2), in the oppsosite corner, my dB's would increase by 3db's.
Is my phasing wrong or is it because one sub is ported and the other is sealed?
The reason that S2 is in opposite corner and not in the same corner, is because of a null I'm trying to correct in Rec listening position.
With both subs in the same corner I do get and increase in dB's , but only at one position. I'm trying to utilize the 2 subs to get a fuller preasurized room.
I have read many times, that if 2 subs cannot be put in the same position (stacked or otherwise), then the subs should be put at opposite corners, adjacent from each other.
Any thoughts that I may be missing?
The room is 16W x 22L x 9H
