Short answer: the GR-Research NX-Treme. It ranks #2 of 228 against #9 of 228 for the Revel F328Be. The NX-Treme images in every direction but is very tall and needs open baffle subwoofers; the Revel’s CEA2034 spinorama shows a flat on-axis response and efficiency above 90dB, though its vertical directivity is asymmetric.
Buy the GR-Research NX-Treme. It is rated higher for sound quality than the Revel F328Be and costs less, which makes it the one to get unless you need something the other one does better.
