Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99; the Technics SB-C700 ranks #82, rated 4.0/5, and costs $1,699, so there is not much of a tradeoff to weigh.
The KEF Q Concerto Meta is the more accurate, deeper-bass choice. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 5.11 for the Technics SB-C700. Its bass reaches about 53Hz before falling 3dB, against 85Hz for the Technics SB-C700. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the Technics SB-C700 does well: Premium bookshelf speakers with a coaxial driver for focused imaging, very consistent sound around the room, and a rigid die-cast cabinet. Watch for: 85dB sensitivity paired with a 4-ohm nominal impedance wants a fairly capable amplifier.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the Technics SB-C700 and costs less, so only choose the other one for a particular feature it does better.
