the "shock and awe effect" of my 4G subliminals

It must be this. I really felt my brain working. This sub feels like 1000x more powerfull than the 3g subs I've tried (BIATW and ASC). The ultasonic version are also more silent.

I'm looking forward to the effects.

With ultrasonics, for some reason, the louder you play them, the more powerfully/intensely they seem to work.

I did use the ultasonic, but I played the other version first to adjust the volume.

I almost only use the ultasonic version. If I play it at the lowest possible/hearable volume ( about 20 % of max volume), I hear almost nothing (or a high pitch that are almost next to zero). If I go to 30 - 60 % volume, I hear a high pitch tone and it's kind of irritating. If I go over 70 % I hear noises of someone speaking.

I probably shouldn't go over 70 %, but my quetion is: will the sub be effective at all in the 30 - 60 % range, when I cleary hear a high pitched scratching noice?

If you're not getting speaker distortion, you're fine.
