Compact 5 to 6.5-Inch PA Speakers
Ranked #3 of 34 in Compact 5 to 6.5-Inch PA Speakers - Alcons Audio VR5 V1 Passive eBay
Pros: High-quality vendor Spinorama data gives preference scores of 4.04 standalone and 7.06 with an ideal subwoofer, and predicted in-room smoothness is 0.73. The pro-ribbon high-frequency driver stays linear at any level, and the compact cabinet suits near-field and stage monitor duty. Measured bass extension of 80Hz (-3dB).
Cons: Bass reaches only about 80Hz (-3dB), and listening-window narrow-band deviation is 0.408, so a subwoofer is needed for music. It is passive and priced by dealers well above ordinary compact monitors.

Ranked #23 of 34 in Compact 5 to 6.5-Inch PA Speakers - 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.

Line Array and Installation PA Speakers
Ranked #7 of 33 in Line Array and Installation PA Speakers - Alcons Audio QR24 Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 4.38 standalone and 7.25 with an ideal subwoofer, with a tight 1.4dB reference band and 0.279 listening-window deviation. Two 12-inch pro-ribbon drivers above four 6.5-inch woofers give 109dB sensitivity and a 135dB peak, and bass reaches 71Hz at -3dB. It works alone or stacked with more modules as a vertical array, in 80° or 110° horizontal versions. Measured bass extension of 71Hz (-3dB).
Cons: Bass drops quickly below about 70Hz, so a subwoofer is needed for full-range music. It needs Alcons Sentinel amplification for its presets, weighs 22kg, and is sold only through pro dealers with no published price.

Ranked #8 of 33 in Line Array and Installation PA Speakers - Alcons Audio QRP40 Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 3.80 standalone and 6.67 with an ideal subwoofer. A 12-inch pro-ribbon driver sits coaxially within eight sealed 5-inch woofers, giving 103dB sensitivity and a 131dB peak with 90° or 120° horizontal coverage. Bass reaches 73Hz at -3dB, and the shallow 236mm cabinet is easy to hide on a wall. Measured bass extension of 73Hz (-3dB).
Cons: A 4.22 directivity-index deviation means off-axis tone varies more than its QR24 sibling, and it needs a subwoofer below about 70Hz. It needs Alcons Sentinel amplification and is sold only through pro dealers with no published price.

Ranked #9 of 33 in Line Array and Installation PA Speakers - Alcons Audio QRP20 Passive eBay
Pros: High-quality manufacturer measurements of the 90° version give preference scores of 3.38 standalone and 6.69 with an ideal subwoofer. A 4-inch pro-ribbon driver on a Morpher lens above four sealed 5-inch woofers gives 99dB sensitivity and a 128dB peak from a slim 150mm-square, 12kg column, with 90° or 120° horizontal versions. Measured bass extension of 90Hz (-3dB).
Cons: Bass reaches only 90Hz at -3dB and about 81Hz at -10dB, so it needs a subwoofer for music. The 120° version measures slightly worse, at 3.00 standalone. It needs Alcons Sentinel amplification and is sold only through pro dealers with no published price.
