Rockport Avior II's in 19x24.5 room?

I am not a subwoofer expert .

I have read that the purpose of using 1 ( or 2 )  subs is not to have more bass.

The idea is to have better low frequencies . The subs , pull back a burdon on the speaker’s  woofers  and maybe on the amplifiers .

So a better over all ,  audio perception .

I also used an acoustician. He designed my room and  while my Avior ii speakers were being built I built my room. Who did you go with? My acoustician was Jeff hedback at hdacoustics. 

I love subwoofers all types cuz it's all about the base😃

@ronboco  I have a friend that is in a firm here in the North Texas area that does primarily large corporate projects.  He is giving me his inputs on diffusion/absorbtion/placement, but I want to finalize my speaker selection before I do a final design with measured performance.  

  I have exchanged a few emails with Jeff and know of his reputation among forum members here and in other forums.  I still might engage him once I take possession of my dream speaker.  I am having some scatter plates CNC’d to use on my DIY acoustic panels.  My interior designer (wife) selected the coordinating color/fabric for the Guilford fabric I am using.

  You obviously did a complete from scratch design and that is quite impressive to say the least.  I should have requested input before I started this build, but I think I can live with the bones of this room as it is built much more solidly than a typical room structure.

It sounds like you are thinking everything through very well. I’m sure your room will sound amazing once you get it all done and don’t forget to share some great pics of it!
