Short answer: the GR-Research NX-Studio on measured sound quality, the Emotiva Airmotiv XB2 on price. The GR-Research NX-Studio ranks #4 of 222 bookshelf speakers, rated 4.8/5, at $3,630. The Emotiva Airmotiv XB2 ranks #48, rated 4.2/5, at $549, $3,081 cheaper.
The case for the Emotiva Airmotiv XB2: A great value bookshelf speaker with neutral sound, an AMT ribbon tweeter, and decent bass for its size. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
The GR-Research NX-Studio is the better-sounding choice. A DIY kit bookshelf speaker with a ribbon tweeter for wide open, detailed sound, superb imaging, and tight, fast sealed bass. The catch: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
Buy the Emotiva Airmotiv XB2 if the price is the priority over sound quality, or the GR-Research NX-Studio if sound quality is the priority over the price.
