d&b Audiotechnik J-Infra — buyer FAQs
What is the d&b Audiotechnik J-Infra and what is it used for?
The d&b Audiotechnik J-Infra is a professional subwoofer cabinet designed for sub-bass reproduction in live sound and permanent installation environments. It is used by sound engineers and DJs who need consistent, deep, clean low-frequency output. Its robust construction makes it suitable for both mobile touring setups and fixed installations.
Who makes the J-Infra and where does it sit in their product range?
The J-Infra is made by d&b audiotechnik, a German professional audio manufacturer founded in 1981 and based in Backnang. The company designs loudspeaker systems, amplifiers and system control software for touring, live sound, theatre and installed applications.

What connector types are found on used J-Infra units?
Used J-Infra subwoofers are found with either EP5 or NL4 connectors, depending on the individual unit. Both types allow integration with existing professional audio setups. Buyers should confirm which connector version is fitted when reviewing a specific listing, as this affects compatibility with amplifiers and cabling already in use.
What protection and accessories typically come with a used J-Infra?
Used J-Infra units are commonly supplied with both hard and soft protective covers, which is useful for transport and storage in touring or mobile contexts. Some units are listed with protective lids only, so it is worth checking what is included with a specific listing. Used units on 10K Used carry a 21-day warranty covering major functional faults; full detail is in the buying guide at https://www.10kused.com/used-av-equipment-guide/.
What affects the price of a used J-Infra subwoofer?
The used price of a J-Infra is influenced by its overall condition, cosmetic wear consistent with age, which connector type is fitted, and what accessories such as covers are included. Units that have seen only local use rather than long-haul touring tend to command higher prices.
