crossover freq nonchangeable
Brackets required. No keyhole slots.
The 2 small speakers have a very tinny sound, good for highs and treble but not much midrange response.
The sub is definitely underpowered and when utilized with the 2 small speakers the sound is terrible. Not even close to reproducing what should be there. For the price of these there are definitely better sounding systems. I would not recommend these speakers.
