Brother, that's low.
Using a speaker as a low-frequency capture mic is nothing new. The Beatles used this technique as far back as the recordings of "Paperback Writer" and "Rain".
Go search your interwebs and you'll find plenty of people dangling a speaker from a make-shift stand, re-wiring a monitor driver, or even hot-wiring a combo amp to try and garner those coveted sub-lows.
Recently, manufacturers and DIYers have taken to wedging a leftover speaker into an repurposed orphan snare or tom drum. Sure, you'll probably get some signal, but it takes more to get the all right pieces in place for the best possible signal at the source, so you get the best possible sound in your ears.
Bring me SOLOMON.
