Short answer: the MoFi SourcePoint V10 Master Edition for deep bass without a subwoofer. It extends to approximately 30 Hz in-room on its own, but moderate sensitivity of ~89 dB means amplifier power requirements higher than many alternatives. The Klipsch Forte IV counters with a three-way heritage design and a 12” woofer, and contrary to Klipsch’s classic reputation it is not forward or bright.
The case for the Klipsch Forte IV: 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.
What the MoFi SourcePoint V10 Master Edition gets right: Extended bass to approximately 30 Hz in-room without subwoofer. The catch: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives.
Buy the MoFi SourcePoint V10 Master Edition. It is rated higher for sound quality, and the $2495.02 saving on the Klipsch Forte IV is not enough to make up the difference.

Klipsch Forte IV: $5,499.98 per pair Amazon Crutchfield eBay
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. Measured bass extension of 82Hz (-3dB), with a measured sensitivity of 93.8dB.
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 $5500/pair, a significant investment, and still needs a subwoofer for material extending below about 50Hz.

MoFi SourcePoint V10 Master Edition: $7995 per pair Crutchfield eBay
Pros: Extended bass to approximately 30 Hz in-room without subwoofer; images with excellent precision indicating tight frequency response matching between speakers. Integrated bass management with three-way treble attenuation switches for room tuning. New design from Andrew Jones represents reviewer personal second choice (behind only KEF Blade 2 Meta at 29k) among hundreds of systems auditioned; ranks above Dutch & Dutch 8C, JBL 4367, and JBL M2. Measured bass extension of 38Hz (-3dB), with a measured sensitivity of 88.8dB.
Cons: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives. Deep bass extension ends above subsonic frequencies (pipe organ territory below 17 Hz requires subwoofer).
