Short answer: the Turbosound NuQ62. It ranks #11 of 16 compact 5 to 6.5-inch pa speakers by sound quality (rated 3.6/5); the Alcons Audio SR9 ranks #16 (rated 3.2/5).
Why pick the Turbosound NuQ62: The lowest price in this ranking for a two-way 6.5-inch box from a major PA brand, with a 6.3kg cabinet and 100° x 60° coverage. Watch for: The Spinorama data is low quality, and predicted in-room smoothness of 0.356 is the weakest of the group.
Why pick the Alcons Audio SR9: High-quality vendor Spinorama data gives preference scores of 2.46 standalone and 6.18 with an ideal subwoofer. The tradeoff: Bass reaches only about 150Hz (-3dB), the shallowest of the group, so it is a fill and speech box that depends on a subwoofer.

Pros: The lowest price in this ranking for a two-way 6.5-inch box from a major PA brand, with a 6.3kg cabinet and 100° x 60° coverage. Bass reaches about 73Hz (-3dB) in vendor Spinorama data, with preference scores of 3.39 standalone and 6.14 with an ideal subwoofer. Measured bass extension of 73Hz (-3dB).
Cons: The Spinorama data is low quality, and predicted in-room smoothness of 0.356 is the weakest of the group. Maximum output of 116dB is modest, and it is passive, so an amplifier is required.

Alcons Audio SR9 Passive eBay
Pros: High-quality vendor Spinorama data gives preference scores of 2.46 standalone and 6.18 with an ideal subwoofer. The RBN401 pro-ribbon and 120° horizontal pattern make it a discreet ribbon-fill and front-fill box, and the sealed woofers give a smooth roll-off. Measured bass extension of 150Hz (-3dB).
Cons: Bass reaches only about 150Hz (-3dB), the shallowest of the group, so it is a fill and speech box that depends on a subwoofer. It is passive, listening-window narrow-band deviation is 0.463, and the very narrow 15° vertical pattern limits placement.
