I've always been a fan of phillips products, they seem to be the perfect blend of price and quality. However the PDF you linked does not say anything about its frequency range. For ultrasonic subliminals we recommend a system that can do at least 20khz (most computer speakers reach this, home theater speakers often go 24khz).
