Short answer: the AsciLab C6B. It ranks #6 of 222 bookshelf speakers by sound quality, rated 4.7/5, at $1,145; the Revel M126Be ranks #38, rated 4.3/5, and costs $4,400, so there is not much of a tradeoff to weigh.
The AsciLab C6B is the more accurate, deeper-bass option. Bookshelf speakers with very accurate sound and an unusually wide, stable soundstage, for any seating position. Its measured preference score, a predictor of how neutral it sounds, is 6.33 against 5.08 for the Revel M126Be. Its bass reaches about 54Hz before falling 3dB, against 103Hz for the Revel M126Be. Watch for: Bass rolls off around 50Hz in-room (F3 54Hz, F10 35Hz), so a subwoofer is needed for real extension below that.
What the Revel M126Be does well: A beryllium tweeter bookshelf speaker with wide, immersive imaging and a smooth, even low end that avoids boominess. Watch for: At $2200/pair, the reviewer doesn’t consider it a strong value: an improvement over the less expensive Revel M106 and other Performa3 models, but not proportional to the price jump.
Buy the AsciLab C6B. It is rated higher for sound quality than the Revel M126Be and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
