Short answer: the AsciLab C6B for a cleaner midrange, the ELAC Debut 3.0 DB63 for far less money. At $469.99 against $1,145, the ELAC saves $675.01, but its lower midrange dips about 1.5dB between 300-600Hz, reducing vocal warmth and making voices sound slightly hollow. The C6B’s 1” aluminum ceramic dome on a large waveguide and 6” ceramic cone woofer roll off around 50Hz in-room (F3 54Hz, F10 35Hz), so both still need a subwoofer below that.
Buy the AsciLab C6B. It is rated higher for sound quality, and the $675.01 saving on the ELAC Debut 3.0 DB63 is not enough to make up the difference.
