Various reviews for them seem to be good, any particular reason for no?
Some time ago another member wanted these, but after getting them he found that they were not that good. I forget who it was, but I remember thinking that I wasn't surprised. Just another gimmcky product in my opinion, particularly the chroma version which adds RGB nonsense. Razer should stick to what they do best.
Much better speakers available for £150, such as; bookshelf speakers + SMSL SA36/SA50 amp, or if you'd prefer to have powered; Edifier R1600T III or Presonus Eris 4.5.
Shame you don't have more space. Creative T40 are OK, but needing speakers with a small footprint is the only reason to get them really. Edifier R1600T III are £10 more and offer a definite increase in quality.
