All user reviews for the KoolSound LS 12

I have a 7 year old who enseinte another 2 years. The difference in quality between the two are huge
Pregnant good quality in a very short time with the above electro ... In 1 year of use tweeters lose quality (becomes too acute and loses sharpness)
The breath of bass also becomes "fat" (dry on good speakers) and saturates it has half power

Save at least double for a minimum purchase of quality ...
Avoid: KoolSound, boost, Ibiza ... All this is the same
Ps: the boxes are mounted with Koolsound boost speakers.
