Data Sheet

ASE02506MS-LW90-DSM-R

PUI Audio’s ASE02506MS-LW90-DSM-R is a Dynamic Speaker Management (DSM)-Ready

micro speaker that has been pre-characterized for use with Maxim’s DSM smart amplifier

solution. This DSM-Ready micro speaker comes prepackaged in a compact enclosure enabling

easy system integration. This turnkey solution vastly increases the loudness (SPL) and bass

response safely and reliably within our strict speaker specifications.

Simply load the provided Vdrx, defined as the voltage required to reach maximum excursion,

into Maxim’s DSM Sound Studio GUI when setting the excursion limit in the “Characterize”

section of the GUI. You are now ready to start tuning! The DSM Sound Studio GUI allows you to

develop a complete register map to customize DSM for your design.

DSM-Ready speaker + DSM Smart Amplifier delivers the easiest and fastest path for designing

a high-performance speaker system in the shortest amount of time.
