Yeah, they screwed up when choosing those spikes for this speaker, but you can use this as an opportunity to get quality spikes and improve the sound. I don't have an opinion, because I went to a Berkeley (music lover's audio) high end shop and they gave me replacement spikes for free just for checking the shop out. What nice people. Anyway, they are adjustable unlike the ones that come with the speaker and work well. I don't know the brand. Just straight spikes with nothing special on them.
