I am so new to the SVS subs you all speak of, so forgive my ignorance. I was just enlightened of their power through this forum and a friend that spends more time here than I do. Anyhow, going through the posts, it seems like most people have SVS 20-39 CS (or CS+) sub(s). Looking at the SVS web page, it looks like the 16-49 is only $50 more (for just one) or $100 more (for the pair). So, I'm curious, given that the price isn't too much more, is there a reason why the 20-39s would be more popular. Being as new as I am to the SVS, it would just seem that the ability to go to 16hz would be awesome, and worth the $50 - $100. This is probably an elementary question, but I was just curious! Thanks for any and all help!
