This small pair of active speakers is a concentrate of my know-how! They are compact monitors, with deliciously detailed and deep listening. Studio, Hifi, they know how to do everything thanks to complete connectivity. RCA 1Volt unbalanced analog line input, coaxial digital, optical toslink, and of course... bluetooth 5.0 Digital amplification and bass/treeble type tone control. 2x30watts rms, 2x60watts peak, sick infras, contained 100hz, warm low mids, open high mids, straight and crystalline highs. The wideband loudspeakers equipping them have an incredible impulse response due to the lightness of the moving masses. Passive membranes extend the bass up to 35 hertz! For the pleasure of the ears! International buyers, contact me before buying!
