Not sure you can send a pm to leecc73 since he only has 1 post. These rules were put in place to prevent folks from not participating just using the forum for spamming, scamming, etc. Maybe the rules have changed?

The smaller cabinet size will raise the lower bass limit of the speaker compared to the full size 9.0s/7.0s. Otherwise all the benefits in a smaller package, great for HT, bookshelf or a system with a subwoofer.
