Short answer: the MoFi SourcePoint 888, unless budget rules. The 888 is a three-way vented design with an 8” coaxial mid-range and 1.25” dome tweeter plus two 8” woofers crossed at about 130Hz, and it costs $5246 more as a significant investment best ordered from a dealer with a good return policy. The Polk T50 has pretty deep bass for the price but a 5dB peak at 1kHz and a 4dB bright top end from 11kHz on up.
On the MoFi SourcePoint 888 side: Three-way vented design: an 8” coaxial mid-range/1.25” dome tweeter driver plus two additional 8” woofers crossed at about 130Hz. The tradeoff: A significant investment, best ordered from a dealer with a good return policy.
The case for the Polk T50: Pretty deep bass for the price. Set against that: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.

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.

Polk T50: $249.00 per pair Amazon eBay
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.
