Do what you think will make you happy that you can afford. The LFRs are a lot more yes, but you have to factor in the HP woofers and additional one for the extra low end extension with the bigger enclosure, additional drivers and tweeters in the back for the omnidirectional effect, and of course the DSP that makes it all work. Also keep in mind you'll have to have a separate amp powering four channels for the LFRs if you don't already. More and more people seem to be getting these and it will be very interesting to see more feedback on them, especially given their price. If they're close to as good as some are saying, it sounds like you can easily get audio nirvana with them set up properly.
