Short answer: the Revel F328Be for measured accuracy, the MoFi SourcePoint 888 for value. The F328Be’s spinorama is quite flat on-axis with superb directivity and efficiency above 90dB, but its vertical directivity is asymmetric, so the reviewer recommends staying between -20 and +40 degrees. The 888’s three-way coaxial design costs $4184.95 less but is still a significant investment best ordered from a dealer with a good return policy.
The case for the MoFi SourcePoint 888: Three-way vented design: an 8” coaxial mid-range/1.25” dome tweeter driver plus two additional 8” woofers crossed at about 130Hz. The catch: A significant investment, best ordered from a dealer with a good return policy.
What the Revel F328Be gets right: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. The tradeoff: Vertical directivity is asymmetric - the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis.
Buy the MoFi SourcePoint 888. Both are rated the same for sound quality, and it costs $4184.95 less than the Revel F328Be.

MoFi SourcePoint 888: $5495 per pair Crutchfield eBay
Pros: Three-way vented design: an 8” coaxial mid-range/1.25” dome tweeter driver plus two additional 8” woofers crossed at about 130Hz, giving genuinely full-range output (F3 34Hz, F10 26Hz) other than the deepest subsonic content. Ranked by the reviewer among his personal top three speakers out of roughly 200 tested, alongside the KEF Blade 2 Meta and Dutch & Dutch 8C, despite costing a small fraction of either. Excellent compression/dynamic-range linearity, holding its own against much pricier speakers like the March Audio Sointuva AWG, KEF Reference 1 Meta, and KEF Blade 2 Meta. On-axis (0°) and 30°-off-axis estimated in-room responses track within about 1-1.5dB of each other above 500Hz, so tonal balance barely changes with placement or listening angle - excellent for multi-seat home theater or entertaining. Wide horizontal dispersion of about ±60°. Distortion stays low: under 1% at 86dB, and under 1% above 200Hz even at 96dB, with multitone distortion mostly under 1% as well. Not a difficult amplifier load (5-ohm minimum impedance, 4.2-ohm minimum EPDR). Checks the three boxes the reviewer considers essential for a home theater speaker: low compression, low distortion, and excellent directivity. Measured bass extension of 34Hz (-3dB), with a measured sensitivity of 85.6dB.
Cons: A significant investment, best ordered from a dealer with a good return policy. Large and heavy floorstander (about 96 lbs, 42” tall) requiring real floor space and rear clearance. Positioning is fairly specific: needs about 2 feet from the rear wall - closer causes boominess in the 40-50Hz region, farther loses bass extension. Vertical dispersion (about ±50°) is narrower than horizontal (about ±60°), since the two 8” woofers are spaced vertically apart on a tower cabinet, causing some vertical mismatch at lower frequencies. A small on-axis dip around 500Hz and a deliberately lower tweeter level (about 0.5dB below the midrange) are intentional design choices for smoother in-room response, but mean the raw on-axis measurement isn’t perfectly flat. A mild diffraction-related dip appears around 3kHz in directivity measurements. Toeing the speaker out more than about 10° starts to noticeably reduce top-end energy.

Revel F328Be: $9679.95 per pair Crutchfield eBay
Pros: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Vertical directivity is asymmetric - the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).
