JOperation the art chamber 300 for 5 years, I am always surprised at the quality and performance, I have rooms of all sizes and I have no worries add 600 art boxes, my amplifier consists of two amplifiers and a filter for two 300 amp art ecler 2 * 300 w 8ohm sub and the boxes I have a channel into 4 ohm 600 w crest of CA6 and the whole filter by a behringer 3 / 4 vote.
I work with my provider who also has bcp and frankly I would not change it ca great speaker, took the remains reasonable for the quality of lenceinte because very little feedback, I try to mackie same range but not at all convinced. If I have to redeem pregnant I took the same without hesitation, see the range of 500 but the 300 are very good.
