You can do ALOT better for 1g. Even svs's lowest model(pb-10) will play alot lower than the polk, above 30-35hz the polk will start to play louder though. I used to be a polk owner & and still visit the polk forum quite often & even the members over there will always recomend a svs/hsu over polk subs, even their top of the line. I love polk, but they just dont get it when it comes to subs for HT.
