Short answer: the Klipsch Forte IV ranks #24 of 25 floorstanding speakers at $5499.98; the MoFi SourcePoint 888 ranks #10 at $5500. Close enough in price that the ranking gap is the deciding factor.
On the Klipsch Forte IV side: Three-way heritage design: a 1” titanium tweeter and 1.75” compression driver for the midrange mated to a 12” woofer. Set against that: Contrary to the classic Klipsch reputation for being forward and bright.
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.
Buy the Klipsch Forte IV if the price matters more than the ranking. Buy the MoFi SourcePoint 888 if the ranking matters more than the price.

Klipsch Forte IV: $5,499.98 Crutchfield Amazon
Pros: Three-way heritage design: a 1” titanium tweeter and 1.75” compression driver for the midrange mated to a 12” woofer, plus a 15” passive radiator for extra bass reinforcement. Genuinely resonance-free cabinet, a clear improvement over the notably boomy, resonant Heresy 4 in the same lineup. Surprisingly wide, expansive soundstage that beat both the Heresy 4 and a KEF LS50 Wireless 2 in direct comparison - images occasionally appeared several feet outside the physical speaker location. Deeper bass extension than the Heresy 4 (F3 of 82Hz, about 10Hz lower). Distortion measures well below 1% at 86dB and stays mostly within 1% even at 96dB. Comes as a factory-matched serial-numbered pair, backed by an unusually generous 10-year warranty. Mostly above 4 ohms impedance, so it’s compatible with AVRs, solid-state, or tube amplifiers. More neutral overall than other Klipsch models the reviewer has tested, making it a reasonable pick for listeners who already like the “Klipsch sound” but want something more balanced.
Cons: Contrary to the classic Klipsch reputation for being forward and bright, this model is actually somewhat recessed in the 1.5-4kHz “presence” region, which can make some tracks sound dull or lacking in detail. A peak around 6kHz reads as sibilant and “painful” when seated exactly on the tweeter axis; sitting a bit above that axis reduces it somewhat. Klipsch’s marketed 99dB sensitivity figure is an in-room rating that assumes 3-6dB of boundary gain - anechoic sensitivity measures closer to 94dB, which the manufacturer does disclose but can still mislead buyers comparing spec sheets. Radiation width isn’t consistent across all frequencies - a noticeable notch around 2-3kHz interrupts otherwise wide dispersion, which can cause a fundamental tone and its harmonics to image in slightly different places in the soundstage. Uses shallow low-pass crossover slopes (despite Klipsch’s steep-crossover marketing, which applies only to the high-pass side), likely contributing to some of the measured dips and possible cone-breakup artifacts. Some compression shows up around the midrange crossover point at very high output (102dB), though likely only audible at extreme volumes. At around $5,000/pair, a significant investment, and still needs a subwoofer for material extending below about 50Hz.

MoFi SourcePoint 888: $5500 Crutchfield
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.
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.
