I am once again in need of a really good shallow mount sub. Not super thin but, it needs to be less than 5.5". There are the usual Image, Arc, and I really like the looks of the Adire Koda. Any other this quality or higher.

Also, has anyone had any experience with MTX Thunderforms? How is the quality of sound?

 

Alianta aka "Phase Linear"

 

i think aura makes one, but it's pretty hard to find a dealer....

 

Pioneer makes one. Only in the Premier line though. Its a 12 thats only 4 inches deep

 

Yeah you need to spec the size.

Blau and Alto have some...
