Key Features:
True Isobaric bass loading – dual bass drivers in a push-pull configuration for tight, extended low-frequency performance
Three-way, six-driver design per speaker
Precision-matched Scanspeak tweeters and KEF B110 midrange drivers
Transmission line cabinet design for superior bass response
Originally designed to be used in active or passive bi-/tri-amp configurations, offering flexibility for serious system tuning
Heavy, inert cabinetry with stunning real-wood veneer finish
Why They’re Special:
The Isobariks are not just speakers – they are a piece of audio history, famously used in Linn/Naim active setups and praised for their ability to disappear into the room, presenting music with lifelike dynamics and precision. Their bass response remains unmatched in many modern designs, even decades later.
Condition:
These speakers are in excellent functional condition, with all drivers operating properly.
Cosmetically, they show light wear/minor marks/very good condition for their age.
If you're an audiophile who appreciates British hi-fi heritage and wants a speaker that delivers both musicality and authority, these Linn Isobariks are a rare opportunity.
