Well, that's hard to know without an actual test with Frequensee to see. You can also download the speaker test sound file from the Subliminal Shop store here: http://www.subliminal-shop.com/product/speaker-test/ and follow the instructions on the page.
Whether or not which is more powerful is a debate somewhat it seems. It's dependant on the person. Ultrasonics are indeed louder, their subliminal audio isn't masked underneath other noise, so the subliminal audio in ultrasonic is at the same level of the max peaks of the masked. So logic would dictate they're stronger, and I can vouch for that school of thought as I use them exclusively and have had massively successful results. However, some people, have a serious fear of loss of control or have a major aversion to others telling them what to do, even if it's something they WANT to do on many levels. Some have very sensitive hearing and can hear the high pitched whine of ultrasonic and it annoys them. So, in those cases, a quieter, softer style like the masked tracks will be more effective.
The good news is, both masked and ultrasonic have been proven effective and have the exact same subliminal information inside them.
Ultrasonic with headphones is not advised at all due to accidental volume changes making the sub too high in volume causing headaches, nausea, and hearing loss. Or accidental volume changes in reducing the volume too much, making the sub ineffective. Now, full disclosure and honesty as I always do, I use ultrasonic with headphones, but with a very special, regimented system to prevent any problems that I know 99.9% of guys won't be as diligent at, every single day, every single time I pickup the headphones, sometimes dozens of times a day. So, to be responsible, I don't endorse doing it and tow the official line saying it is not recommended for the aforementioned reasons.
Masked with headphones and speakers with ultrasonic is more than enough to get you to where you want to be!
