Short answer: it depends on whether you want tight bass or deep bass. The GR-Research NX-Studio’s sealed woofer enclosure gives very tight bass that will not go as deep as others, though its burst decay and waterfall plot are ultra clean. The ELAC Debut 3.0 DB63 instead pairs a 6.5-inch aramid fiber cone woofer with a partial-lens waveguide tweeter, but a 1.5dB dip from 300-600Hz reduces vocal warmth.
Buy the ELAC Debut 3.0 DB63 when the price outweighs sound quality for you, and the GR-Research NX-Studio when sound quality outweighs the price instead.
