Fulcrum Acoustic RX5 - ranked #17 of 18 Compact 5 to 6.5-Inch PA Speakers · Editor's rating 3.3/5

#17 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.

How it compares: Just above it: Fulcrum Acoustic RX599. Just below it: Alcons Audio SR9.
