Most all speakers benefit from spikes, I prefer Apex and audiopoints "spikes". I have spent some time with SC-IV's and they sounded much more precise(larger soundstage) with more defined bass on cones. Its really simple to install cones, all you do is find out what size you need- this would depend on the weight of the component and the carpet(a VERY plush carpet may need a larger cone). To put them on all you do is get a set of 6 cones for the pair of speakers(3 per speaker). I believe the dunlavy's may by slightly front heavy, though they are fairly well balanced front to back(some components are not); in which case I would recommend putting 2 cones on the front side- a few inches from each corner- and 1 in the rear center a few inches in. If they seem to be heavier in the rear, put two in the back and one in the front, pretty simple eh? Audiopoints offers an in home audition and they aren't that expensive so you have nothing to loose and on carpet a lot to gain. It can be tricky "spiking" a component but when you get the hang of it, its a piece of cake! You may want a friend to help you the first few times. Good luck and let us know what you think if/when you do it.
