Meyer Sound Ultra X20 vs Alcons Audio SR9

Why pick the Meyer Sound Ultra X20: Manufacturer measurements give preference scores of 2.88 standalone and 5.68 with an ideal subwoofer, and bass reaches 69Hz at -3dB, deep for two 5-inch woofers. Watch for: Its standalone score trails its narrower-coverage Ultra X22 sibling.

The case for the Alcons Audio SR9: High-quality vendor Spinorama data gives preference scores of 2.46 standalone and 6.18 with an ideal subwoofer. Watch for: 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: Manufacturer measurements give preference scores of 2.88 standalone and 5.68 with an ideal subwoofer, and bass reaches 69Hz at -3dB, deep for two 5-inch woofers. The concentric 2-inch compression driver keeps coverage consistent across its 110° x 50° horn, and a built-in 860W peak amplifier with Meyer’s processing makes it a complete self-powered system. At 7.5 inches wide it suits fills, theaters and discreet installs. Measured bass extension of 69Hz (-3dB).

Cons: Its standalone score trails its narrower-coverage Ultra X22 sibling. A 123.5dB peak rating limits it to small and medium spaces, and a 3.73 directivity-index deviation means off-axis tone varies. It is sold through pro dealers with no published price.

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.
