DSP (digital signal processing) is onboard computing that actively reshapes a speaker’s output in real time, rather than a fixed analog crossover or a simple bass/treble knob. Of the 144 ranked speakers where we’ve checked, only 108 actually have it, and every one of them is a serious powered speaker.
Having an amplifier and having DSP are not the same thing. Most powered speakers do the first without the second.
What Does DSP Actually Let A Speaker Do?
Room correction. B&O’s Beolab20 adapts its output for free-standing, wall, or corner placement; KEF’s LS60 does the same across normal and expert modes. Neither is possible with a fixed analog crossover, which can’t change its behavior once it’s built.
Real multi-band EQ, not a tone knob. The Dutch & Dutch 8C runs a 24-band parametric EQ through its DSP. See speaker EQ explained for why band count is what separates genuine correction from a cosmetic boost.
Alignment and calibration software. Genelec’s GLM and Neumann’s MA 1, both DSP-dependent, are full measurement-and-correction tools rather than a volume-and-EQ panel; see the companion app explainer for what that software actually looks like day to day.
DSP Isn’t A Requirement For A Speaker To Sound Good
Plenty of highly-ranked speakers here have no DSP at all and never needed it: a well-executed analog crossover and a well-chosen driver set can measure flat without any real-time correction running. DSP is a tool for reaching a target response electronically, not a guarantee that a speaker sounds better than one without it. What DSP does buy is flexibility a fixed design can’t match: adapting to a corner instead of open space, or running a genuinely deep parametric EQ instead of a handful of fixed bands.
Where Does DSP Show Up?
Every speaker with DSP in this data is a premium powered speaker: nearfield and midfield studio monitors from Neumann, Genelec, and HEDD, and DSP-driven “smart” home speakers like the B&O Beolab20 and KEF LS60. It isn’t a feature portable Bluetooth speakers or budget powered speakers carry.

Frequently Asked Questions
What does DSP mean on a powered speaker? DSP, digital signal processing, is onboard computing that actively reshapes a speaker’s output in real time, for things like room correction and multi-band EQ, rather than a fixed analog crossover or a simple tone control.
Is DSP the same thing as having an amplifier? No. Most powered speakers have an amplifier without DSP. DSP is a separate, additional processing layer that only a subset of powered speakers, mostly premium studio monitors, actually include.
Does a speaker need DSP to sound good? No. A well-executed analog crossover and driver set can measure flat without any real-time correction. DSP buys flexibility, like adapting to a room or running a genuinely deep parametric EQ, not a guarantee of better sound on its own.
Which speakers here actually have DSP? Of the 144 ranked speakers where we’ve checked, only 108 do, and all of them are premium powered speakers: studio monitors from Neumann, Genelec, and HEDD, and DSP-driven home speakers like the B&O Beolab20 and KEF LS60.
