Klipsch makes good speakers. But if you're looking for a rich 2.0 hi-fi experience, these are going to underwhelm in an open room. This is a decent near-field system, such as to use at the PC or with a digital keyboard. But you're not going to get good low-end without a subwoofer.
My current near-field PC setup is Klipsch RB-61 II bookshelf speakers with an Onkyo TX-8020 receiver and dual Klipsch SW-110 10-inch subwoofers. The bookshelf woofers are 6.5-inch, and even near-field I'd never go back to anything smaller. The system is actually sufficient without the subwoofers, which I have wired to the B channel for easy muting.
The RB-61 II have been replaced by the RP-160M. Something with a comparable frequency response really is desirable if you're going to be listening at a distance, and especially if strictly 2.0.
So what if you're not budgeted for a larger system, and you're merely looking to improve your PC setup? Well, the R-14M can definitely do that. But there's one problem: You can currently pick up a pair of either these or the more powerful R-15M from Klipsch for $199.00, leaving you with $159.99 to spend on a receiver. A receiver like the Onkyo TX-8020 is going to give you things like a basic equalizer, two channels, multiple inputs, comprehensive remote control, capable 1/4 headphone output, and more. The downside is that a stereo receiver is going to come with a large footprint, which may make this bundle more appealing in some environments (my receiver is mounted overhead on a shelf, which I find easy to access). The optical input is nice, too (invaluable for resolving ground-loops). And while I personally don't have any use for Bluetooth or Wi-Fi, you might. But buying the speakers and an amplifier or receiver separately is certainly worth considering.
Anyway, my experience with the Klipsch reference series has been great. Some people find the horns tinny; but I feel this is really just a negative reaction to hearing accurate speakers. The detail is excellent and can make listening to old albums a new experience if your ears haven't known better. And if you do find them too bright, it's nothing that can't be tamed with an equalizer.
