THE CONTENDER

ADAM Audio T7V

Black

Full product profile Official image
Exact model & source notes

The T7V is a single active two-way nearfield monitor with a 7-inch polypropylene woofer and ADAM's 1.9-inch U-ART folded-ribbon tweeter, driven by 50 W and 20 W RMS PWM amplifiers. It takes balanced XLR or unbalanced RCA inputs and is sold individually, so a stereo pair means buying two.
