I know from reading, you based the samples on the most popular BK Gamer unit, which in turn then should work pretty well with the following: Using only between 5-10% volume to keep it at a reasonable level. I did find, testing with the biggest Buttkicker LFE that some of the current sound samples are very strong and a bit overbearing with the lowest frequencies. Its excellent you provide a demo working for 20 mins for free. Seems simple to use, I'm keen to play around with this to check out the effects, enjoyed the brief moment I had with it thus far but will be purchasing in the near future and support your progress.
