Hey about 6 weeks ago i bought a ken kreisel DXD12012, and by the reviews this should be more then enough for anyone. Boy was i wrong, this did not perform in my home(having living room/kitchen of 60m2 and open stairway up to an equal area in second floor). I even ended up having specialists home and no luck, i had to turn output bass to maximum in the reciever and this is just wrong. And now im in search for a one that works... Jl audio Fathom 113 is one that im considering trying out, but i need convinsing that this is the one... I want more than just the deepest bass. Oh almost forgot, i tested the kk dxd 12012 at a friends 25m2 room and it sounded better then i have ever heard period!
