Coverage note. Speaker Ranking currently covers 15 HSU Research models across passive speakers and subwoofers. These are the products in our database, not a complete list of everything HSU Research makes.
What this page covers. The HSU Research models ranked here span passive speakers and subwoofers, including HSU Research ULS-15 MK2, HSU Research VTF-2 MK5 and HSU Research VTF-3 MK4. Use each model’s category position to compare it with alternatives of the same size and use case.
This page lists all 15 HSU Research speakers ranked on this site across passive speakers and subwoofers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Large Size Bookshelf Speakers
Ranked #99 of 134 in Large Size Bookshelf Speakers - HSU Research MFL-6: $558 per pair HSU Research eBay
Pros: A high-output 6.5-inch design with horn-loaded tweeter, strong measured sensitivity and flexible wall, stand or horizontal placement. The local Spinorama snapshot delivers a solid 2.63 raw score and 4.77 with a subwoofer, with controlled horizontal radiation and 45Hz extension. Measured bass extension of 77.6Hz (-3dB), with a measured sensitivity of 85.6dB.
Cons: Its response deviation is substantial and the horn narrows dispersion, so tonal balance and seating coverage are less even than the best conventional monitors. The trapezoidal cabinet and utilitarian finish are optimized for function rather than furniture-grade appearance.

Ranked #127 of 134 in Large Size Bookshelf Speakers - HSU Research CCB-8: $699 per pair HSU Research eBay
Pros: Legitimately good midrange and mid-bass punch below about 1kHz, with in-room bass extension to about 60-70Hz that’s impressive for an 8” coaxial driver running this high a sensitivity (~90dB measured). Wide horizontal dispersion (~55 degrees) that holds up reasonably well off-axis. Measured bass extension of 65Hz (-3dB), with a measured sensitivity of 90.4dB.
Cons: Badly unbalanced top end that the reviewer called ‘just a terrible speaker’ outright: a roughly 7dB peak-dip swing in the upper mid/treble causes real listening fatigue regardless of listening angle (tried on-axis, 15 degrees off, and 30 degrees off, all bad). Resonances around 600Hz and 1.2kHz plus erratic high-frequency behavior hurt imaging noticeably. Would need 9 bands of EQ to get close to flat, and even then two dips near 2kHz and 8kHz are baked into the crossover and can’t be fixed with EQ at all: the reviewer’s verdict was simply to skip it.

Ranked #32 of 146 in Medium Home Subwoofers (30-75 lbs) - HSU Research VTF-2 MK5: $759 HSU Research eBay
Older model: the HSU Research VTF-2 MK4 (ranked lower, rated 3.7/5).
Pros: Plays 50% louder across measurement range than competitors. Tuneful bass, antithesis of one-note. Variable tuning provides flexibility: like having three subs in one. Compact size for tight spaces. Extreme value. WireCutter/NYT recommended.

Pros: 15-inch ported driver delivers 121.8dB CEA-2010-A average from HSU Research’s long-running VTF series.

Ranked #86 of 109 in Large Home Subwoofers (Over 75 lbs) - Hsu Research VTF-TN1: $1,199 eBay
Pros: Independent CEA-2010 testing (2 ports open) records 107.8 dB at 20 Hz and 117.6 dB through 40-80 Hz. Variable tuning via dual 4” down-firing ports lets the 15” driver reach 15Hz in Max Extension mode or 18Hz in Max Output mode. Extremely low distortion until the highest drive levels.
Cons: The tall 29.5” cabinet has an unusual footprint compared to squatter subs in this class.

Large Home Subwoofers (Over 75 lbs)

Newer model: the HSU Research VTF-15H MK2, ranked higher, rated 4.2/5.
Pros: Independent CEA-2010 testing records 107.1 dB at 20 Hz and 118.4 dB through 40-80 Hz. The ported, front enclosure with 15” (381mm) driver has the headroom for demanding film bass in a large room.
Cons: The 635.0H x 457.2W x 660.4D mm cabinet and 55.8 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential. Discontinued.

Ranked #97 of 109 in Large Home Subwoofers (Over 75 lbs) - HSU Research VTF-3 MK3: $1499 Discontinued eBay
Newer model: the HSU Research VTF-3 MK5 HP, ranked higher, rated 4.2/5.
Pros: Independent CEA-2010 testing records 104.3 dB at 20 Hz and 113.5 dB through 40-80 Hz. The ported, rear enclosure with 12” (305mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 546.1H x 431.8W x 635.0D mm cabinet and 40.8 kg mass still require deliberate placement and calibration. Discontinued.
