Short answer: the ELAC Debut 2.0 B6.2. It ranks #149 of 222 bookshelf speakers by sound quality, rated 3.5/5, at $479; the HSU Research MFL-6 ranks #166, rated 3.3/5, and costs $558, so there is not much of a tradeoff to weigh.
The ELAC Debut 2.0 B6.2 is the more accurate, deeper-bass pick. Large bookshelf speakers that play very loud with low distortion and decent bass, a solid budget choice. Its measured preference score, a predictor of how neutral it sounds, is 4.75 against 2.63 for the HSU Research MFL-6. Its bass reaches about 64Hz before falling 3dB, against 77.6Hz for the HSU Research MFL-6. The tradeoff: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference.
What the HSU Research MFL-6 does well: An affordable high output bookshelf speaker with a horn loaded tweeter, easy to drive, that can sit on a wall, stand or sideways. The tradeoff: Its response deviation is substantial and the horn narrows dispersion, so tonal balance and seating coverage are less even than the best conventional monitors.
Buy the ELAC Debut 2.0 B6.2. It is rated higher for sound quality than the HSU Research MFL-6 and costs less, so only choose the other one for a particular feature it does better.
