Wavesfactory has released a free plug-in for they 7th anniversary called SK10 - Subkick Simulator.
A subkick is a large diaphragm microphone intended to accentuate the low frequencies of the source material. It's usually used on kick drums in order to get extra oomph by combining it with a regular kick mic, but it can also be used on other instruments like acoustic pianos.
SK10 emulates a subkick and it blends it with the original signal, designed to give the user an extra push on the low end.
Price: Free.
