FYI when an avr is said to be 7.2 when it comes to the sub it simply means there are two ports/jacks to connect...there is no 7.2 in terms of content. Some sub ports can have seperate level/delay adjustments for two subs but only on higher-end avrs generally, usually simply an internal splitter offering the same content. Talking about a 7.1 soundtrack is different from a 7.2 or 7.4speaker setup (but still playing 7.1 content)...
