Deep, deep bass from Whise Profunder 319A subwoofer

My review of the Whise Profunder 319A subwoofer ($6,499) appeared in Wednesday’s ‘Connect’ section in the Melbourne Herald Sun newspaper, unfortunately under someone else’s name. No matter. The graph herewith is something I couldn’t put in the article. This shows the in-room frequency response of this sub. Ignore the dip at 36 hertz. That’s an artefact of microphone/subwoofer location in my particular room. Just look at how deep it goes. The roll-off at the bottom end is not as steep as I would have expected from the enclosure design, so I reckon it’s still delivering some output at 15 hertz.
