Hello,\n I have recently added two css sdx 12” subwoofers up front each with its own crown xls 2002 bridged ( 2100 watts ) and two css sdx 10” in rear powered by a behringer km 1700 ( about 400 watts per ch.) all In sealed enclosures built to spec.\nMy front speakers are 3 Boston acoustic vr m90’s and both My side and rear surrounds are Boston vr m60.\nThe bostons are powered by a Yamaha rxv 2700. With a mini dsp HD.\nMy room is L shaped. The main part 14 x 18 with a 9x 10 making up the smaller part of the L shaped room.\nMy question .\n I assumed I would get more volume out of my subs . I have to turn the gain down through my reciever on all my speaker to -4 to level match my subs.\nIf I turn the the gain on my crowns past 3 o’clock I get clipping and my subs can bottom out .\nI do have the output gain sat on my mini dsp Hd set so that at max volume on avr ( I limit it to -10) with Jurassic park scene I use to test limits I don’t go into the red with the gain.\n I love my set up and I think the css sdx subs sound great but I feel like I am doing something wrong and my output is suffering .\n Are my expectations to high?\nI bought the crowns because they claim 2100 watts and my subs are 1000 watts rms so I thought I would have plenty of headroom but I seem to be at the limits . I do have my crown amp sensitivity set to the lowest option . \n Also the two sdx 10” running off the 400 watt behringer are only a couple of db below the 12” sdx running off the 2100 watt crown.\n Just doesn’t seem right.
