Each of my subs are just outboard of my LRs about 15 feet apart. One is an Outlaw LFM EX down firing and the other is an Aperion S-12 Front firng. They are pretty capable of any LFE in my HT and they sound good with music. Ideally I would have wanted the Outlaw behind the seating position but WAF overruled a cable running across the floor. The Outlaw is huge compared to the Aperion. The LFM EX could do double duty as an end table.
