room setup suggesion needed

@ssg308 Your speaker's frequency response is rated at one meter. What they do in a 30 foot room is TOTALLY different, not to mention that you need at least an additional 10 dB of gain to get realistic bass levels. You can only do this with 2 15" subwoofers or more in your room. I use 8 12" subwoofers in a 16 X 30 foot room. Each one gets 1300 watts.

As for as your sources are concerned you should have a better DAC, a Bricasti Design M3 would be perfect. Your turntable is not the greatest, but your tonearm and cartridge do not belong in the same room as your amp, preamp and speakers. You do not have to spend big money either. Get a Thorens TD 1600 and put a Soundsmith Voice in it. It will blow your mind. 

@mijostyn  here is the answer, like always it lays in numbers, 8 12" mathematically 

should do better job than 2 25" but in fact they don't there fore subwoofer is backing up the system with sonic boom. I don't have that problem in a fact I need to move my speakers off the wall farther to control my overwhelming bass.

As far as the sources, my TT is just something I like to play with but I'm not using it as the main source. DAC on the other hand is what I need to develop a bit better and I'm looking for alternative to what I have. I was looking in to the streamers/servers and as of now I'm not sure if I like the idea, sending digital signal from any computer shouldn't  be a issue, it's only matter of software and file quality, DAC on the other hand can do big difference so I definitely take your advise and look in to Bricasti Design M3

@ssg308, quality, properly set up subs will not add "boom". They will not only add more detail to the lower frequencies but will enhance the sound at higher frequencies as well. You will not be able to to localize the sound from the subs, it will be a part of the soundstage.

 I have also had success taming bloated bass by closely adhering to the 1/3rds rule. Speakers moved out from the front wall at 1/3rd of the total room length and the listening position 1/3rd of the way from the back wall. Tweaking the distances from there. 

@ssg308, bass boom does not come from speakers or subwoofers. Bass boom is a product of room distortion see here.

Anyone who thinks they know anything about how their speakers sound in a room because of the specs is probably mistaken.  The room changes everything and measurements are key.

The ability to limit the bass in main speakers and move subs to ideal locations can be life changing, as are bass traps and sub EQ.
