KEF Q Concerto Meta vs GR-Research NX-Studio

What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

What the GR-Research NX-Studio offers: Ultra clean burst decay/waterfall plot. Amazingly open sounding due to the semi open baffle Neo3 ribbon tweeter, will image better than any other bookshelf speaker. Neo3 ribbon tweeter is one of the best ribbons around for detail. Bass will be very tight and fast due to the sealed enclosure, but may possibly need a sub. Watch for: Bass will be very tight but won’t be quite as deep as others due to the sealed woofer enclosure.
