It is better trust us. If you don't have a subwoofer skip the 1712. If you dont have a sub but plan on getting one, get the 1712. The reason we are telling you this, especially for a lower budget, is to get the Max potential for the money spent, to avoid upgrade bug sooner than later and the better your speaker system the more you'll notice , or depending on how you look at it, won't notice the difference in how your speakers and subs interact with each other. The xt will help your sub disappear in your soundstage to simplify things if I was trying to sell it to you.
butter and jelly please.
