Compact 5 to 6.5-Inch PA Speakers
Ranked #17 of 18 in Compact 5 to 6.5-Inch PA Speakers - Fulcrum Acoustic RX5 Passive eBay
Older model: the Fulcrum Acoustic RX599 (ranked higher, rated 3.3/5).
Pros: The updated 5.25” coaxial RX speaker, with a new crossover and horn for better off-axis response and 90 x 75 degree coverage. Fulcrum’s own measurements on spinorama.org hold the listening window within 1.5dB from 300Hz to 5kHz.
Cons: Bass stops early, about 128Hz (-3dB), so it needs a subwoofer, and on-axis response is uneven (1.15dB average deviation), for a preference score of 1.76 alone and 5.64 with an ideal subwoofer. The measurements are Fulcrum’s own, and it is sold through installers only.

Still ranked, and often still worth buying used, but no longer in production. Check availability before planning around one of these.
Compact 5 to 6.5-Inch PA Speakers
Ranked #12 of 18 in Compact 5 to 6.5-Inch PA Speakers - Fulcrum Acoustic RX699 Passive Discontinued eBay
Pros: A 5.4kg coaxial cabinet with a 90° x 90° pattern and a 16 ohm load that lets many speakers share one amplifier channel. Vendor Spinorama data gives preference scores of 2.98 standalone and 6.54 with an ideal subwoofer. Measured bass extension of 109Hz (-3dB).
Cons: Bass reaches only about 109Hz (-3dB) and maximum output is 118dB, so it suits speech and background music rather than loud programs. Listening-window narrow-band deviation is 0.406, and it is passive, so an amplifier is required. Discontinued.

Ranked #16 of 18 in Compact 5 to 6.5-Inch PA Speakers - Fulcrum Acoustic RX599 Passive Discontinued eBay
Newer model: the Fulcrum Acoustic RX5, ranked lower, rated 3.3/5.
Pros: A compact coaxial installation speaker with a 1” compression driver at the center of a 5.25” woofer, rated at 93dB and 115dB maximum. Fulcrum’s measurements hold the listening window within 0.9dB from 300Hz to 5kHz, and the score reaches 5.91 with an ideal subwoofer.
Cons: Bass stops early, about 125Hz (-3dB), so it needs a subwoofer, and on-axis response is uneven (1.09dB average deviation), for a preference score of 2.13 alone. The measurements are Fulcrum’s own. Replaced by the RX5. Discontinued.
