I will explain why I use the 6 of Jacintha is her name album. The contrabass is on the left side of the recording. Wenn you put the subwoofer on the right side you can hear how it integrates with the speakers. First the contrabass needs to be very small in dimension also with the subwoofer. Often wenn you but it to on/off you hear the contrabass becomes less focussed or bigger wenn the sub is set to on. Second point all the energy and drive of the contrabass need to be coming from the left side even wenn the sub is standing on the right side. With most subs the contrabass becomes less sharp focussed or bigger. You can easily hear the energy coming from the subwoofer. Wenn I let people hear this number with my sub they think and know for sure it is off. They are amazed that it is comming from the subwoofer. At a big audio show this year most people didn't understand. They never heard a subwoofer this integrated wit the speakers. That is why I call this stealth inegration. Full integration. Even wenn the low freq. are recorded far behind the speakers ( in depth) you will hear it is coming from there. I use Audyssey pro with my way of measurment to get this level. I measure at different places and hights compared to Audyssey. This way is far superior to the way Audyssey uses it. ( so much more dynamics, better focus and more resolution) There way is ok, but I use it from highend perspective. Without this measurement you never will come even close to stealth integration. But you also need sub's who are fast like a rocket. Like Revel sub's and the PLW-15 from Monitor Audio. And sub's who are sealed.
