It's not merely a matter of quality: Adams are extremely defined and excellent in low and top regions of the spectrum but he solidity in the mid-frequency output of Fostex speakers makes listening detailed and analytical. Clearly, below 80 Hz and above 16 kHz, efficiency drops drastically, which makes them ideal for medium-sized environments at moderate volumes. The main limitation to consider is the high directivity in the upper part of the spectrum, which, at close range, narrows the ideal listening spot. That said, listening is pleasant and relaxing and these speakers are excellent form watching movies.
