Hello, not strictly a rew question and more to come! I hope someone can help as I am pulling my hair out!!
I have a room that gives very bad responses and this is probably because its square and the listening position needs to go quite close to the back wall.
The room has a big peak at 40 pretty much wherever you place the sub in the room at mlp.
The response across a two seat sofa varies greatly in the 60 to 100 range (moving the mike 4 inches really makes a difference) which is why I want to try 2 subs.
The first problem I am trying to address though is why 2 subs always appear worse than one.
I have 2 subs but of different types. If I can get this to work I will replace both to get matching subs.
I have been taking lots of responses over the past couple of days and one consistent issue is the output from 2 subs is always worse than 1.
The output is significantly down in every case and the flatness of response either worse of at best the same.
I am hoping this is user error but I can't figure it out.
Using a minidsp I mute the subs and consistently in all the positions I have tried either one of the subs has more output and a more even response than the 2 together.
The gain structure does not change.
I have tried changing phase on one sub.
I have set distances correctly and then tried increments from 0-7.5
I have tried colocating and facing the drivers together a few inches apart and I have stacked the subs on top of each other facing the same way.
All in varying degrees have either single sub looking better than both together.
The subs are different with one being a 15 diy sub and the other being a very capable manufacturer 12 sub.
Any help as to what to try would be hugely appreciated.
