Short answer: the Buchardt Audio E50 if sound quality matters most, the Emotiva Airmotiv XB2 if price matters most. The Buchardt Audio E50 ranks #16 of 222 bookshelf speakers, rated 4.5/5, at $4,600. The Emotiva Airmotiv XB2 ranks #48, rated 4.2/5, at $549, $4,051 cheaper.
What the Emotiva Airmotiv XB2 does well: A great value bookshelf speaker with neutral sound, an AMT ribbon tweeter, and decent bass for its size. The catch: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
The Buchardt Audio E50 is the deeper-bass choice. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its bass reaches about 40Hz before falling 3dB, against 62Hz for the Emotiva Airmotiv XB2. The tradeoff: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
Buy the Emotiva Airmotiv XB2 if the price is the priority over sound quality, or the Buchardt Audio E50 if sound quality is the priority over the price.
