#18 Fulcrum Acoustic RX8 Passive eBay
Pros: Vendor measurements give preference scores of 2.49 standalone and 5.91 with an ideal subwoofer, and the on-axis response is very even (0.78dB average deviation). At 6.4kg it is light for an 8-inch coaxial, and the 16 ohm load lets several share one amplifier channel. Measured bass extension of 109Hz (-3dB).
Cons: Bass rolls off early for an 8-inch speaker, at about 109Hz (-3dB) and 86Hz (-10dB), so pair it with a subwoofer. Its directivity index varies more than the RX6 (5.05dB deviation), so off-axis tone changes more. It is passive and sold through pro dealers with no published price.
How it compares: Just above it: Vue Audiotechnik H-8. Just below it: LD Systems Stinger 28-A-G3.
