Linn 343 Exakt Integrated vs PWAB: Which Should You Choose?
Linn 343 is available in two versions that share the same cabinet, Pistonik drive units and active bass platform but take very different approaches to crossover, amplification and system design. Here is how Exakt Integrated and Passive with Active Bass compare.
If you are comparing Linn 343 Exakt Integrated vs PWAB, the most important thing to understand is that these are not simply two specification levels of the same loudspeaker. They share the same 343 cabinet, drive units and Pistonik bass architecture, but they are designed around two very different ways of building a Linn system.
343 Exakt Integrated contains the crossover processing, DACs and amplification required to drive the complete loudspeaker within its integrated electronics module.
343 Passive with Active Bass (PWAB) keeps Linn’s powered Pistonik bass system inside the speaker but leaves the upper 343 Array to external amplification.
That distinction changes the equipment you need, the way the system is connected and how much flexibility you retain over external power amplification.
If you are new to the range, our Linn 343 explained guide covers the loudspeaker as a whole. This comparison concentrates specifically on choosing between the two versions.
Linn 343 Exakt Integrated vs PWAB: the key differences
Both versions are four-way floorstanding loudspeakers built around the same core acoustic platform.
They use the same:
- 19 mm thin-ply woven carbon dome tweeter
- 64 mm thin-ply woven carbon dome midrange
- 190 mm aluminium Pistonik upper-bass driver
- down-firing 220 mm aluminium Pistonik lower-bass driver
- 43-litre cabinet
- 338 mm width
- 1091 mm height
- 466 mm depth.
The real difference lies behind those shared components.

What is Linn 343 Exakt Integrated?
The Linn 343 Exakt Integrated is the more self-contained version of 343.
Linn describes it as a fully integrated active loudspeaker for Exakt applications.
Its rear electronics module contains several Linn technologies that would otherwise sit elsewhere in the system:
- Utopik power supply
- Exakt digital crossover
- Organik DACs
- Adaptive Bias Control amplification for the 343 Array
- Power DAC architecture for the bass system.
This means the loudspeaker itself handles the digital crossover, digital-to-analogue conversion and amplification needed by its drive units.
The source side of the system can therefore remain comparatively simple because much of the downstream audio architecture already exists inside each speaker.
What is Linn 343 Passive with Active Bass?
The Linn 343 Passive with Active Bass, normally shortened to PWAB, takes a more traditional approach to the upper part of the loudspeaker.
Its lower-bass system remains active and uses Linn’s Utopik-powered Power DAC and Pistonik architecture.
The 343 Array, consisting of the upper-bass, midrange and tweeter sections, is instead driven by external amplification.
The loudspeaker therefore includes three pairs of binding posts for the upper array, alongside an XLR input for the active bass section.
PWAB also includes an Exakt Link connection so that the system can be developed into an external Exakt architecture using an Exaktbox and six channels of amplification.
Which version needs separate power amplifiers?
This is one of the quickest ways to separate the two options.
343 Exakt Integrated
You do not need separate power amplifiers to drive the loudspeaker.
The amplification required for both the 343 Array and lower-bass section is built into the speaker architecture.
That makes Exakt Integrated particularly attractive if you want to reduce the number of external boxes in the system.
343 PWAB
You do need external amplification for the 343 Array.
The bass section powers itself, but the upper-bass, midrange and tweeter sections rely on the external amplifier system connected through the loudspeaker’s binding posts.
This makes PWAB much more relevant if you already own amplification you want to retain or deliberately prefer a separates-based system.
What does Exakt Integrated actually change?
In a conventional passive system, the power amplifier sends an amplified full-range analogue signal to the loudspeaker, where a passive crossover divides it between the drive units.
343 Exakt Integrated does this differently.
Its crossover is digital.
Exakt processing handles the signal before amplification, allowing the relevant frequency information to be sent through the appropriate conversion and amplifier channel for each section of the loudspeaker.
This is why the Integrated version does not need the three pairs of binding posts found on PWAB.
The music reaches the loudspeaker through Exakt Link rather than through conventional amplified speaker-level connections.
If you want the underlying technology explained in more detail, our Linn technology section covers Exakt, Organik and Linn’s wider digital system architecture.
What is inside the Linn 343 electronics module?
The electronics are housed within a dedicated rear module beneath the curved cowl of the cabinet.
Linn has mechanically isolated this module from the loudspeaker cabinet using a three-point spring mounting system. The design is intended to reduce the mechanical interaction between the cabinet and the electronics housed within it.
The module is also passively cooled. Linn’s documentation describes a custom aluminium heat sink with internal fins that creates a chimney-style airflow path, carrying heat upwards and out through the machined vent at the top of the loudspeaker.
This means there is no cooling fan operating inside the module.
What does Adaptive Bias Control do in 343?
343 Exakt Integrated uses Class AB amplification with Linn’s Adaptive Bias Control for the 343 Array.
This is part of the integrated amplifier architecture driving the tweeter, midrange and upper-bass sections.
The important buying point is that this amplification is specific to the Exakt Integrated version.
PWAB does not contain this upper-array amplifier architecture because those drivers are deliberately left for an external amplifier to control.
Do both Linn 343 versions use Pistonik?
Yes.
This is one of the most important things the two versions share.
Both use a 190 mm Pistonik upper-bass driver and a down-firing 220 mm Pistonik lower-bass driver.
Linn says the lower-frequency drive units together handle around 70% of 343’s acoustic workload.
The lower-bass section in both versions also uses Power DAC.
This means choosing PWAB does not mean losing the core Pistonik bass architecture that Linn developed specifically around 343.
Do both versions use Utopik?
Yes, but the extent of the powered electronics differs.
Exakt Integrated uses Utopik as part of the complete integrated electronics system that powers and controls the loudspeaker.
PWAB uses Utopik to support its active bass system.
The difference, again, is that PWAB leaves amplification for the upper 343 Array outside the speaker.
Does PWAB use Organik DAC?
Not as part of the standard integrated upper-array architecture described in Linn’s launch specification.
The Exakt Integrated version specifically includes Organik DACs inside its module.
PWAB instead takes an analogue passive approach to the upper array in its standard configuration, with that section driven by external amplification.
If PWAB is developed into an external Exakt system, the relevant digital processing and conversion then sit within the external Linn hardware used to create that system.
This is an important distinction if Organik is central to the system you intend to build.
How does Space Optimisation differ?
The two versions also differ here.
343 Exakt Integrated uses Space Optimisation+.
343 PWAB supports Space Optimisation with a Linn DSM.
This reflects their different architectures rather than one speaker simply having “more room correction”.
Exakt Integrated gives Linn digital control further through the loudspeaker system itself.
PWAB’s normal operating mode retains the external amplifier and analogue passive crossover architecture for the upper array.
Which Linn 343 is best if you already own high-end amplification?
PWAB is the obvious version to investigate first.
It exists specifically to give owners freedom over external amplification for the 343 Array.
If you already have power amplifiers that you value and want to retain, PWAB allows them to remain part of the system while Linn’s active Pistonik bass system handles the lower frequencies.
The decision should still be made in the context of the complete system.
Existing amplification should be retained because it fits the system you want to build, not merely because it already happens to be in the rack.
Which Linn 343 is best if you are starting from scratch?
Exakt Integrated becomes particularly compelling when there is no existing amplification architecture to accommodate.
Because the loudspeaker already contains its own Exakt crossover, Organik DACs and amplification, there is less need to assemble those functions from separate external components.
This can create a surprisingly clean system for a loudspeaker operating at this level.
The source or system hub still matters, but the speaker side of the system is already highly integrated.
Which version gives you more freedom over amplification?
PWAB.
This is its strongest architectural difference.
You can choose the external amplification used for the 343 Array rather than using Linn’s integrated Adaptive Bias Control amplifier system.
That could appeal if you already own suitable amplifiers, want to compare different amplification options, prefer a separates architecture or want an external Exakt route later.
With Exakt Integrated, Linn has already made those decisions as part of the loudspeaker design.
Which version has fewer boxes?
343 Exakt Integrated.
This is one of the unusual aspects of the product.
The more technologically integrated version actually allows the external system to become simpler because the DAC, crossover and amplification functions move inside the loudspeaker.
PWAB can involve considerably more external hardware depending on the amplifier system you choose.
Neither approach is inherently better.
They reflect two different ideas about how a high-level system should be constructed.
Can Linn 343 PWAB become an Exakt system later?
Yes.
Linn specifies PWAB as Exakt-capable when used with an Exaktbox and six amplifier channels.
The loudspeaker provides one Exakt Link connection for this external Exakt operation.
This gives PWAB an interesting development path.
You can begin with external analogue amplification and later move towards an Exakt architecture without changing the fundamental 343 loudspeaker platform.
Rococo’s Klimax Exaktbox page provides context for one of Linn’s external Exakt processing routes.
Are the cabinet and drive units different?
No.
This is important because it means the comparison should not be framed as a higher and lower loudspeaker mechanically.
Both versions share the same 43-litre composite cabinet, external dimensions, tweeter, midrange, Pistonik upper-bass driver and down-firing Pistonik lower-bass driver.
The different weights come from their different electronics and system architectures rather than different cabinet sizes.
Do the finishes differ between Linn 343 Exakt Integrated and PWAB?
No.
Both launch in the same six finishes:
- Triton
- Single Malt
- Clyde Built
- Linn Heritage
- Piano Black
- Alpine White.
The 343 Array trim is black on both versions.
Linn’s supplied launch specifications do not list a custom-finish option for either version.
Linn 343 Exakt Integrated vs PWAB: which should you choose?
Choose Linn 343 Exakt Integrated if…
- you want Linn’s most integrated 343 architecture
- you want Exakt built into the loudspeaker
- you want Organik DACs inside the speaker system
- you want Linn’s Adaptive Bias Control amplification for the 343 Array
- you want fewer external boxes
- you are building a new Linn system rather than preserving existing amplification.
Choose Linn 343 PWAB if…
- you want to choose or retain your own external amplification
- you prefer a separates-based system
- you still want Linn’s Pistonik and Power DAC active-bass architecture
- you want the possibility of moving to an external Exakt system later
- you already have a source and amplifier system you want 343 to join.
Which Linn 343 architecture fits your system?
The central question in Linn 343 Exakt Integrated vs PWAB is not which version contains the longer technology list.
It is where you want the system’s amplification, crossover and digital conversion to live.
Exakt Integrated places those functions within the loudspeaker and creates Linn’s most self-contained 343 system.
PWAB keeps the same Pistonik-driven bass platform but leaves the upper array open to the external amplification architecture you choose.
Rococo Systems can help compare both approaches in the context of your room and any equipment you already own. Proper positioning and configuration are also important with a loudspeaker of this size and system complexity, so our Linn installation and setup service can form part of the planning process.
