What you purchased, unfortunately, is not standard. I'll explain why.
Basics: Hz stands for Herts, which was a man's name, and which has now been applied to the concept of one cycle per second. So to say a frequency response range for a speaker is 180 Hz to 18 kHz means that the speaker won't start producing sound until it is given a signal that would equate to 180 vibrations per second. The lowest a typical human can hear is 22 Hz, and the lowest standard CD recording and playback frequency is 20 Hz. On the other end, you have your speaker working at a top end of 18 kHz, which is 18,000 cycles per second. Well above what a typical person can make out, but fully 2,000 Hertz below top end hearing and CD recording and playback upper limit. CD format standard is 20 Hz to 20 kHz. Anything but the cheapest speakers will follow this standard, and if what you bought wasn't correspondingly cheap in price, then you got ripped off.
In effect, what you have purchased is sub-standard speakers that were produced sub-standard to even the basic standard CD format specifications, no doubt because most people don't know what that stuff means and can't typically tell the difference anyway. However, our ultrasonic subliminals have a frequency range of 14.5 kHz to 20 kHz, so by limiting the upper band to 18 kHz, you don't cut out all of it, but you do distort it somewhat. It would be about like listening to ocean surf without any treble... it is still recognizable as ocean surf, but will sound off somehow.
Now given that you are dealing with ultrasonics and your system specs (I presume for the laptop) max out at 18 kHz (surprising and disappointing, to be sure - they cut corners everywhere they can these days to make an extra buck I guess), getting better speakers probably will not help unless you are stating that your built-in speakers max out at 18 kHz. If the speakers built in max out at 18 kHz, you should still be able to play 18-20 kHz sounds on standard speakers. In that case, I would either just use the ocean surf, or return your speakers and get some that are designed to at least standard spec for CD playback.
You can probably get results out of such speakers, but we go to great lengths to preserve those parts of the program above 12.5 kHz in pitch because that's where the subliminal audio is in an ultrasonic. So probably is the best I can say - I offer no certainty of success when these programs are played on non-standard speakers with non-standard frequency response ranges.
