Con artists in this type of scam call themselves "speakerguys" or "speakermen", and usually claim to be working for a speaker delivery or installation company.
To find suitable targets, the van operators set up their con in moderately trafficked areas, such as parking lots, gas stations, colleges, or large apartment complexes.
The con artists will repeatedly state the speaker's "value" as anywhere between the equivalent of $1800 and $3500, prices often purportedly verified by showing a website, brochure or a magazine advertisement.
Some of these fictional brands have reputable-looking websites which list customer service telephone numbers and support e-mail addresses, but these methods of contact are often dead ends.
Among these techniques are producing glossy material that details the quality and high retail value of the speakers, and bombarding the potential customer with technical jargon, whether correctly or incorrectly used.
