Xi-28B

Installation subwoofer black
Discontinued product
The XI Series is designed for installation use. The Top cabinets have special mountings at the backside which fit the DAP D8429 compact speaker wall bracket but also most common universal brackets. To create a nice design it has no inner adapter and only one grip on the backside with a recessed Speakon chassis. It is finished with scratch resistant paint and a fast and easy detachable metal grill. The horn (Xi-8/10) can be rotated if you like to use the cabinet vertical. The high power Subwoofer has a ultra-compact design so it will fit in every location. A special designed wall bracket makes it also possible to mount the subwoofer to a wall. The Xi-series has a HIFI sound quality and can handle high pressure levels.


The Xi-28B is a compact lightweight subwoofer designed to combine with the Xi-series top cabinets. Together with the optional Xi-28B bracket it can be installed flat against the wall which makes it very suitable for situations were space is limited. The two 8” speakers and the sophisticated bass reflex horn housing offers a very powerful precise bass sound reproduction with high sound pressure levels.
