I have had my 1027's for a number of years. But, until recently, I never bothered to care if they were spiked or not. It turns out they were not. I have a carpet floor. It is not super plush or anything like that, but it does sink a bit. I also did not know that the port, which is a slot formation, is underneath the speaker. So that port was probably flush with the ground and really not doing much. Well, I did spike them. I can tell right away that there is a difference. The bass is more defined which makes sense. But also, voices and the mid range are also much better. I would suggest to anyone who has not spiked their speakers, to give it a try. I think you will like the results.
