Okay, I've had a look at cables and speaker pads (I decided I'm going to have the speakers on my table rather than on stands). For speakers, I found these:

I really want something that keeps the speaker level and doesn't have a bit covering the front, I'm afraid it'll cover the Yamaha logo that lights up. I found a picture that shows this but I haven't found the product. Is it available, would I have to get it custom-made, etc.? I have no idea...

Also, concerning cables I found a cheaper cable that is 3m instead of 5m. Do cables differ in quality based on price? It has good reviews but I don't know anything about cables. I looked at the reviews and I believe it's splittable. Also, the speakers have an XLR output. Is this preferred for music or is it strictly for microphones?
