Ultra Rare Vintage 1980s Pioneer CK Series Boombox Monster. The tag is still attached. Tested & working.

THE HOLY GRAIL OF 1980S BOOMBOXES: VINTAGE PIONEER CK SERIES . I turned it on just now. Its working fine.

Calling all audio collectors, vintage restorers, and 80s audiophiles. This is the machine you’ve been hunting for.

Up for grabs is an incredibly rare, hyper-modular Pioneer CK Series Portable Component System. This isn't your standard plastic boombox—this is a heavy-duty, multi-stack absolute powerhouse from the golden age of Japanese audio engineering.

WHY THIS UNIT IS A COLLECTOR'S DREAM:
• Flat Woofer Dynamic Sound: Features Pioneer’s iconic, legendary square flat-panel woofer design.
• Ribbon Tweeters: Equipped with high-fidelity ribbon tweeters for crisp, crystal-clear high frequencies that modern setups fail to replicate.
• Modular Stacking: The center features a heavy multi-deck layout including Graphic Equalizer slider controls and the "Sound Echo" dual mixing/cassette system.
• Insane Connectivity: Check the back layout! It features dedicated Phono/Auxiliary RCA inputs.

CONDITION & TESTING DETAILS:
• It has been kept in storage, unused. Works
• Cosmetically, it is in beautiful, completely intact vintage condition with original speaker cables attached.

These Pioneer CK "Flat Woofer" setups are nearly impossible to find in Ireland and easily command massive money globally.

Grab a rare piece of audio history.

Collection preferred due to the substantial weight and size of this beast.
Open to sensible offers.


I would prefer collection but for the right buyer (Kilbeggan, Tullamore, Blanchardtown, Beaumont, City centre).
