Short answer: the HiVi Swans 3.1A Sehlin Sound Solutions mod, a DIY three-way kit with a mostly smooth on-axis response. Its one noted fault is some directivity error around 2.1kHz on-axis. The ELAC Debut 2.0 B6.2 is a finished speaker with reasonably flat on-axis and listening-window response, but it shows a good size resonant peak around 700Hz and a directivity error around 3.3kHz.
Buy the HiVi Swans 3.1A Sehlin Sound Solutions mod. It is rated higher for sound quality than the ELAC Debut 2.0 B6.2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
