Room Treatments - ATS Corner Bass Trap

I have posted often my system’s week link is my listening room, a shared listening/living room.  The configuration, a 20’ x 12’ room, with a 11’ x 14’ dining room  in an L- configuration on the left and a hall on the right, is for the most part an open configuration.  Therefore, there is adequate venting to prevent wave reinforcement and cancellation, or at least I thought.   The room was untreated until now due to esthetic considerations and the WAF.  I finally purchased and installed an ATS Corner Bass Trap today and there was an immediate improvement in the following SQ attributes:  

• Bass detail is much improved, especially the secondary harmonics and the ability to discern the strings from the body of instruments.
• Dynamics have greater impact. 
• Detail in general across the frequency range is improved.  
• Staging is deeper and wider with improved density and dimensionality of images. 
• Timbre, most important to me, is improved.

So for years, I have underestimated the reinforcement and cancellation effects occurring in my room masking detail and I underestimated the positive effects that relatively inexpensive room treatments can bring.  I still will long for a treated, dedicated listening room, but for now am very happy with the improvements realized today.  Thanks to all that posted on the benefits of room treatments.
