Short answer: a tie on sound quality. Both are rated 3.6/5 (#40 and #38 of 89 bookshelf speakers) at nearly the same price ($699.99 vs $699), so choose on features and fit.
The case for the KEF Q1 Meta: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. The tradeoff: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies.
What the Triangle Esprit Titus EZ does well: High 90dB specified sensitivity, a lively horn-loaded titanium tweeter and compact real hi-fi cabinetry. The catch: The 62Hz measured extension still calls for a subwoofer, while the 3.8-ohm minimum impedance demands a competent amplifier.

The Two Speakers In Full
KEF Q1 Meta: $699.99 per pair Amazon eBay
Older models: the KEF Q150 (rated 3.7/5) and the KEF Q100 (rated 2.4/5).
Pros: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. KEF’s own Spinorama measurements, published on spinorama.org, hold the 300Hz to 5kHz response within 2.3dB with a flat on-axis trend, so the tonal balance is even. Measured bass reaches 65Hz (-3dB) and about 43Hz (-10dB), respectable for a compact bookshelf. Same cabinet size as the Q150 it replaces. Measured bass extension of 65.1Hz (-3dB).
Cons: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies. Sound power directivity is less even than the best in this class (3.16dB index deviation), so off-axis listeners and room reflections shift the balance more. Minimum impedance of 3.2 ohms is a harder load than the Q150’s, and rated maximum output is a modest 108dB, so plan on a subwoofer for loud listening.

Triangle Esprit Titus EZ: $699 per pair Triangle Hi-Fi eBay
Pros: High 90dB specified sensitivity, a lively horn-loaded titanium tweeter and compact real hi-fi cabinetry. Its local Spinorama scores are 4.24 raw and 6.98 with a subwoofer, supporting a capable small-room system. Measured bass extension of 73.4Hz (-3dB).
Cons: The 62Hz measured extension still calls for a subwoofer, while the 3.8-ohm minimum impedance demands a competent amplifier. Horn/directivity behavior makes setup and toe-in more consequential.
