Thought the Pioneer speakers with those dual forward/upward speaker design would do the job. Well it didn't.
It's extremely important that this sort of speaker be wired properly and that the setup in the AVR is done properly. In a recent optimization I performed, the AVR was set up to send "rear" speaker audio to the "upward" speaker (these were for the "height" speakers in my particular instance). Obviously a less than ideal situation. The wiring or setup may have been incorrect in the installation you viewed. This stuff is not so easy to set up, even with the "auto speaker setup" if the AVR is configured incorrectly... Need to pay particular attention to the setup for rear or zone, etc. speakers
