I have some infinity reference comps in my accord, and my friends got some infinity kappa comps in his. Both sets kick major arse, the kappas give a little more midbass and can hit the high frequencies a little better than the reference but its all good for the price i got them for (got mine at ikesound too! I got mine in about a week, like the others said, the packaging was a little lacking but no damage at all)
