Design and Build Quality
From the moment I unpacked the Demand D17, I appreciated its solid construction. The sleek, modern design with a glossy black or white finish fits well in most living rooms without being intrusive. The compact tower design makes it easier to place in smaller spaces compared to bulkier floor-standing speakers.

What really impressed me was the sound clarity and depth. The Demand D17 features a 1-inch aluminum dome tweeter and dual 5.25-inch mid/bass drivers, which deliver crisp highs and rich mids.

They deliver near high-end sound quality and build at a price point that’s accessible to many audiophiles and home theater enthusiasts.
