Our Experience

Spectra and their Asia subsidiary, IMA-Hong Kong, LTD., have been an integral part of the consumer electronics business for the past 40 years.

Spectra has supplied products to every major retailer in the United States, and has conducted business on every continent in the world. In addition to retailers, Spectra is successful in premium, direct mail, catalog, and online channels.

Spectra has been producing JENSEN brand audio products since 1998, and most recently launched the SōLIS brand of audio products created for people who value iconic styling and exceptional sound quality in equal measure.

Over 15 years ago, Spectra formed a strategic partnership with Marino Andriani, LLC. to provide unique product lines like Studebaker brand retro audio products and turntables, Karaoke Night brand karaoke machines, and others.

Spectra and their Asia subsidiary, IMA-Hong Kong, LTD. are owned privately by Patricia Schoenberg who, through her lifelong career in the consumer electronics business, has molded Spectra and IMA into companies who design, develop, manufacture and distribute products worldwide.
