I replace my original icotec gc350 speaker with the Speco SPC12RP. Has high power rating, and a better frequency range then the TOA 610 (according to specs). I have used the same sounds vs the foxpro hellfire and I cannot tell a difference on any of the mp3/wav files, high or low pitch sounds. Size wise they are about the same, the speco would probably be a hair lighter since the horn part is plastic vs the metal TOA 610.
