i just can't get over the vocal clarity and separation of sonics on these speakers. it's truly amazing. they have solid balanced bass all the way throughout. these are carefully engineered, quality speakers at an unbelievable price point. no bells and whistles to disguise faults in sound like other manufacturers. these are the real deal.
you'll be okay w/o having a sub for a while.
sometimes i turn the sub off so i can see where he's coming from i guess. there are some acoustic albums that sound better w/o a sub (or they don't use much of it to even notice). while some albums excel with a sub. so i'd save up until you can at least get something from the STF series. just my opinion at least.
