To ask Tvad a quick question, have you ever heard a Von 4jr go down to 16hz? or should I say felt?VR4 Jr, no. They are not rated to 16Hz.

My recommendation was for the VR4 Gen III HSE, which are rated to 16Hz, and yes I have measured them with an SPL meter to below 20Hz using the Stereophile Test CD.
