Short answer: the Pro Audio Technology LFC-24sm on measured sound quality, the HSU Research VTF-3 MK5 HP on price. The Pro Audio Technology LFC-24sm ranks #4 of 143 subwoofers, rated 4.6/5, at $10,000. The HSU Research VTF-3 MK5 HP ranks #59, rated 4.2/5, at $1,049, $8,951 cheaper.
The case for the HSU Research VTF-3 MK5 HP: A 15 inch ported subwoofer with excellent output for the money, a strong value pick for movies and music. The catch: Ported design requires careful room placement, mid-size 86 lbs (39 kg) cabinet, and mid-range output.
The Pro Audio Technology LFC-24sm is the better-sounding option. A giant 24 inch ported subwoofer with enormous deep bass output, built for large dedicated cinema rooms. The catch: The 660.4H x 1536.7W x 533.4D mm cabinet and 266.1 lbs (120.7 kg) mass still need deliberate placement and calibration.
