Short answer: the HSU Research VTF-15H MK2 for output, the Power Sound Audio (PSA) XS15SE for a sealed cabinet. The HSU’s 15-inch ported driver delivers a 121.8dB CEA-2010-A average against the XS15SE’s 117.8dB, but the ported design is prone to room modes and the 50 kg (110.2 lbs) cabinet is mid-large. The XS15SE’s compact sealed enclosure gives up that output.
What the HSU Research VTF-15H MK2 gets right: 15-inch ported driver delivers 121.8dB CEA-2010-A average from HSU Research’s long-running VTF series. Set against that: Ported enclosure prone to room modes at certain frequencies, mid-large 50 kg (110.2 lbs) size, and $1,500 price point.
On the Power Sound Audio (PSA) XS15SE side: 15-inch sealed driver delivers 117.8dB CEA-2010-A average in a compact sealed enclosure.
