ทรงmonitor มีเพาว์เวอร์ในตัวครับตามรูปเลยสภาพดีCarlsbro EM70 Powered and Passive Wedge Monitors 70W on the passive wedge but ive no idea about the active as it doesnt say..., 12" dual concentric speaker Nice compact wedge with it's own volume control. Quite battered but works fine. I was using it as an extension from a powered wedge. The active wedge has two outputs. One has come lose and dropped inside the case but the second can be used to power the passive wedge.
