Short answer: it depends on how much deep bass you need. The GR-Research NX-Studio’s sealed enclosure gives very tight bass that will not go as deep as others, though its burst decay and waterfall plots are ultra clean. The ELAC Debut 2.0 B6.2 is reasonably flat on-axis with even horizontal directivity, but it carries a good size resonant peak around 700Hz and a directivity error around 3.3kHz.
Buy the ELAC Debut 2.0 B6.2 if the price is the priority over sound quality, or the GR-Research NX-Studio if sound quality is the priority over the price.
